ResMed ClimateLineAir 11 Manual
ResMed Manual: ClimateLineAir 11 complete user guide, setup, cleaning & troubleshooting
You might end up having to look at the Resmed AirSense 11 user’s manual if you use a Resmed AirSense 11 CPAP machine and a ClimateLineAir 11 heated tube. You may be wondering about the tubing connection, temperature setting, proper cleaning or a message like “ClimateLine connected.”
This ResMed ClimateLineAir 11 manual guide provides simple explanations of most of the important information. It aims to educate the patient, caregiver and CPAP user about the use of the heated tubing and the need to maintain it as a complete AirSense 11 therapy system.
The ClimateLineAir 11 is more than an ordinary CPAP hose. This is a hot breathing tube for use with compatible Air11 devices. Combine with HumidAir 11 humidifier to help control the temperature and humidity of the air delivered during therapy with AirSense 11 Climate Control system.
Always check current ResMed user documentation included with your equipment or manufacturer’s support resources for official instructions.
What is the ResMed ClimateLineAir 11?
The ResMed ClimateLineAir 11 is an air tube for use with compatible ResMed Air11 devices, such as ResMed AirSense 11 platform.
A normal CPAP tube just transports the air blowing from the machine to the mask. The ClimateLineAir 11 can also be used for heating humidified air being passed through the tubing.

This can be particularly useful when using the AirSense 11 with its humidifier.
The basic therapy path is simple:
AirSense 11 → HumidAir 11 humidifier → ClimateLineAir 11 tubing → CPAP mask → user
The heated tubing forms part of ResMed’s Climate Control system.
For many people, this means a more controlled and comfortable breathing environment during CPAP therapy.
Why Is Heated Tubing Important?
If warm, moistened air is blown through tubing, then the air may cool on the way towards the mask. This can sometimes lead to condensation in the tubing or mask, depending on the humidity and temperature in the room.
In CPAP users, this is referred to as rainout.
The rainout may lead to water droplets accumulating in the tube or in the mask. Nobody wants to get up to find water spraying around in his or her CPAP mask.
Heated tubing is used to control the temperature of the air as it flows through the system.
The ClimateLineAir 11 is therefore part of the important comfort items that users can enjoy when using the AirSense 11’s Climate Control.
ResMed ClimateLineAir 11 Manual: What You Need to Know
Before using the tubing, it is helpful to understand a few basic points.
The ClimateLineAir 11:
- Is a heated breathing tube.
- Is designed for compatible Air11 devices.
- Connects to the air outlet on the back of the device.
- Connects to the mask at the opposite end.
- Works with the HumidAir 11 humidifier for Climate Control functionality.
- Requires proper cleaning and drying.
- Should be inspected regularly for damage.
- Should not be placed in a dishwasher or washing machine.
- Should be replaced if it develops holes, cracks, or other damage.
One important detail is easy to overlook: the end containing the electrical connector is intended for the device side, not the mask side.
Do not force the tubing connection. If something does not fit correctly, stop and check the orientation and compatibility.
Is ClimateLineAir 11 Compatible With AirSense 11?
Yes. The ClimateLineAir 11 is specifically built for the Air11 platform.
According to ResMed documentation, the heated tubing pair that is compatible with the Air11 device is the ClimateLineAir 11. This is significant because CPAP tubing may be very similar even if it’s intended for a different machine.
For instance, the tube that fits an older AirSense 10 system may not work as a heated tube for an AirSense 11 system.
Why Compatibility Matters
The ClimateLineAir 11 is electrically connected to the AirSense 11, which is able to detect and control the heated tubing.
The basic tube is not as functional.
When buying replacement tubing, if you have an AirSense 11, read the product name and packaging.
The right replacement part can minimise connection issues and avoid returns.
How to Set Up ClimateLineAir 11
Setting up the ClimateLineAir 11 is straightforward.
Before beginning, make sure your equipment is placed on a stable surface and that the machine is connected correctly.
Step 1: Turn On or Connect the Device

When correctly connected, the AirSense 11 can display a message indicating that the ClimateLine tubing has been connected.
Step 5: Connect the Mask
Repeat with the other end of the tubing and put it together with your CPAP mask.
Mask connection is tight but not tight enough that it needs excessive force.
Step 6: Check the System
Before starting therapy, check that:
- The tube is firmly connected.
- The mask is connected correctly.
- The humidifier tub is properly installed if you use humidification.
- There are no visible tears or cracks.
- Air is not leaking from an improperly connected tube.
Once everything looks correct, you can begin therapy according to your prescribed AirSense 11 settings.
Understanding Climate Control on AirSense 11
The biggest benefit of the ClimateLineAir 11 is its integration with the AirSense 11 Climate Control system.
Climate Control helps control the temperatures and humidity in therapy.
Depending on the equipment and settings, the AirSense 11 can be used in various manners as a Climate Control system.
Climate Control Auto
The Auto mode is created to simplify the humidification process.
The user will not have to constantly adjust humidity and tube temperature, but the system will do this automatically.
It can be helpful for those who are not motivated to try out various comfort levels.
Auto is a good default option for many users.
Climate Control Manual
Manual mode provides more control.
Manual mode: Control of temperature and humidity is independent of one another.
This may be helpful for those with changing comfort requirements between nights or changing comfort requirements due to the weather.
For instance, someone can find it dry in winter, but more humid than in summer.
Another person might see the condensation and so have to manipulate the temperature of the tube or humidity.
The key is to make sure comfort settings are adjusted carefully and in accordance with the equipment directions.
What Does “Manual” Mean on AirSense 11?
A significant difference between ClimateLineAir 11 manual and Climate Control Manual mode.
These two are not synonymous.
The “ResMed ClimateLineAir 11 manual” likely refers to the product’s manual or instructions.The term “ResMed ClimateLineAir 11 manual” typically refers to the user guide or instructions for the product.
In contrast, “Manual” in the AirSense 11 Climate Control setting is a setting where the user can set humidity and temperature independently.
Knowing this difference can help to make it easier to find help.
The ClimateLineAir 11 user guide includes instructions on how to use the physical tubing.
You are seeking information on the AirSense 11’s Climate Control settings if you are attempting to change the humidity and temperature of the tubes.
ClimateLineAir 11 Temperature Settings
Heated CPAP tubing is an important component of temperature.
A comfortable temperature is a personal preference and may vary from one user to another.
If the air is on the cool side, you might want to use a higher tube temp.
If the air is hotter than it seems, a lower setting might be more comfortable.
The AirSense 11 automatically controls the tube temperature in Auto mode.
When using Manual mode, the user has greater control.
Manual mode is from the AirSense 11 documentation, where the temperature and humidity can be adjusted separately.
Never adjust the pressure of the medication you are prescribed.
Humidity and tube temperature settings are comfort settings, which are different from therapeutic pressure settings.
How to Adjust Humidity With ClimateLineAir 11
The humidifier increases the humidity of the air.
For some individuals, CPAP therapy is more comfortable with a humidifier to increase the level of moisture in the air.
Too high humidity levels can lead to condensation, though.
One way to do this is to focus on what you are feeling.
If Your Nose or Mouth Feels Dry
May need more humidity.
Increasing the humidity level may help improve comfort.
If You See Water in the Mask or Tube
You might have an excess amount of moisture or not enough tube temperature for the environment.
Lower humidity or warmer tubes will be helpful in lowering condensation, depending on the settings.
If the Air Feels Too Warm
If you prefer to have a lower temperature, you can.
Make small changes, make no big changes.
Keep in mind that other factors such as room temperature, humidity, type of mask, mouth breathing and more can also impact CPAP comfort.
How to Clean ClimateLineAir 11
Cleaning CPAP equipment is a crucial aspect of its maintenance.
Clean the ClimateLineAir 11 as per the manufacturer’s guidelines.
A simple cleaning procedure is to clean the tubing with warm water and a mild household dishwashing detergent.
Step 1: Disconnect the Tubing
Disconnect the ClimateLineAir 11 from the AirSense 11 and mask prior to cleaning.
Do not clean the tube while it’s plugged in.
Step 2: Wash the Tubing
Clean the air tubing in warm water with a dishwashing detergent.

According to the manufacturer’s instructions, the temperatures the tubing should not be washed at are over 131°F (55°C).
Step 3: Rinse Thoroughly
Wash the tubing thoroughly with clean water.
Make sure soap residue has been removed.
Don’t want to inhale soap that is left in the tubing.
Step 4: Allow It to Dry
Let the tubing dry in the shade and out of direct heat.
Hang it or put somewhere where it will get air circulation.
Ensure that it is 100% dry before reconnecting it.
Can ClimateLineAir 11 Go in a Dishwasher?
No.
ClimateLineAir 11 heated tubing is not dishwasher or washing machine safe.
This is a major distinction from some other CPAP parts, such as the heated tubing.
While the specific instructions for cleaning the humidifier tub may vary, the instructions do not necessarily apply to the heated tubing.
Please read each manufacturer’s instructions.
How Often Should You Clean ClimateLineAir 11?
A proper cleaning regimen will help you maintain your CPAP equipment in good condition and clean.
ResMed’s instructions recommend that the air tubing be cleaned weekly.
A practical routine is:
Disconnect → Wash → Rinse → Dry → Inspect → Reconnect
This type of exercise is easy to remember.
When the tubing becomes visibly dirty, smells ory unusual or when it has been exposed to something that needs cleaning, clean it as directed by the manufacturer.
How to Inspect ClimateLineAir 11 for Damage
Cleaning is also a good opportunity to inspect the tubing.
Look carefully for:
- Small holes
- Cracks
- Tears
- Split cuffs
- Damaged connectors
- Visible wear
- Other signs of deterioration
Even a small hole can affect the air delivered through the system.
If the tubing is damaged, replace it rather than trying to repair it with tape or adhesive.
A temporary repair may not maintain the proper seal and could interfere with therapy.
How to Dry ClimateLineAir 11
Just as vital as washing is drying.
Clean and dry the tubing.Rinse and dry the tubing out of direct sunlight and heat.
Using a hair dryer or setting the tube near a heater is not recommended.
CPAP components can be damaged by excessive heat.
Prior to re-using the tubing, ensure there is no water left in it.
This is particularly important if you have humidification equipment.
What Does “ClimateLine Connected” Mean?
When connected properly, the AirSense 11 can identify the heated tubing in the ClimateLineAir 11.
The device may briefly display a message such as:
ClimateLine connected
This means that the heated tube connection has been identified by the system.
If you don’t see the connection message, ensure tubing is connected properly and that you’re using the right ClimateLineAir 11 tubing.
Do not repeatedly force the connector into place.
If the issue persists, refer to the AirSense 11 user guide or contact an authorised AirSense 11 support resource or qualified medical equipment provider.
ClimateLineAir 11 Not Heating: What Should You Check?
Sometimes a user may feel that the tubing is not heating.
When trouble with tubing occurs, make sure to check basic connections before assuming that the tubing has failed.

Check the tube, particularly the cone of the tube.
Inspect for cracks, damage, or abnormal wear.
5. Restart and Recheck
If necessary, refer to the manufacturer’s instructions to start the equipment up again and recheck the connection.
If it still doesn’t function as desired, please reach out to ResMed support or your medical equipment provider.
Never open, modify or electrically repair the heated tubing.
Why Does My ClimateLineAir 11 Have Water Inside?
Intubing (condensation) or “rainout” can cause water to be trapped in the tubing.
When air with moisture content is cooled to a point where moisture condenses.
Several factors can contribute:
- High humidity
- Low bedroom temperature
- Tube temperature settings
- Environmental humidity
- Mask and tubing conditions
Humidity and tube temperature can be adjusted if in Manual mode in Climate Control.
In the event that it rains out, the ResMed documentation suggests that the temperature of the tube can be raised first. If air is too warm and condensation is still occurring, try to lower the humidity.
This can differ from person to person, depending on the setting that they are comfortable with.
ClimateLineAir 11 vs. Standard CPAP Tubing
A standard CPAP tube and a heated ClimateLineAir 11 tube both move air from the machine to the mask, but they are not identical.
| Feature | ClimateLineAir 11 | Standard CPAP Tubing |
| Carries CPAP air | Yes | Yes |
| Heated | Yes | Usually no |
| Electrical connector | Yes | No |
| Works with AirSense 11 Climate Control | Yes | Limited/not the same |

What is ClimateLineAir 11 Heated Tubing?
ClimateLineAir 11 is a heated breathing tube made for compatible ResMed Air11 devices.
Unlike ordinary CPAP tubing, heated tubing contains technology that helps manage the temperature of the air as it travels from the machine toward your mask. When used with the appropriate humidifier and Climate Control features, the system is designed to provide a more controlled temperature and humidity experience.
ResMed identifies ClimateLineAir 11 as the heated tubing designed for its Air11 platform. ResMed’s current product information lists the tubing as compatible with AirSense 11 and AirCurve 11 machines.

This makes it different from older ResMed heated tubing designed for previous generations of machines.
If you own an AirSense 10, for example, you should not assume that AirSense 10 heated tubing is interchangeable with AirSense 11 tubing. The Air11 platform has its own ClimateLineAir 11 tubing.
In simple terms
Think of the ClimateLineAir 11 as the connection between your PAP machine and mask that helps control the conditions of the air traveling through the tube.
It is designed to:
- Deliver air from the machine to your mask
- Provide heated tubing functionality
- Work with the Air11 Climate Control system
- Help manage condensation inside the tubing
- Support more comfortable humidified therapy
- Connect directly to compatible AirSense 11 and AirCurve 11 devices
For many users, the biggest benefit becomes noticeable on cool nights or when humidification creates condensation inside standard tubing.
Is ClimateLineAir 11 Compatible With AirSense 11?
Yes.
The ClimateLineAir 11 heated tubing is specifically designed for the ResMed AirSense 11 platform.
ResMed states that ClimateLineAir 11 is the heated tubing compatible with AirSense 11. The tubing connects to the dedicated air outlet on the rear of the machine.
Once connected correctly, the AirSense 11 can recognize the heated tubing.
The machine may briefly display a message indicating that the ClimateLine tubing has been connected.
This automatic recognition is one reason it is important to use the correct Air11 tubing rather than trying to adapt tubing from another ResMed platform.
Why compatibility matters
CPAP tubing may look simple, but heated tubing is more than a hollow plastic tube. The heated tube has an electrical connection that communicates with the compatible PAP device.
Using the correct tubing helps ensure that the machine can use its intended Climate Control functionality.
If you have an AirSense 11 and want heated tubing, look specifically for ClimateLineAir 11 rather than simply searching for generic “ResMed heated CPAP tubing.”
Is ClimateLineAir 11 Compatible With AirCurve 11?
Yes.
ClimateLineAir 11 is also designed for the ResMed AirCurve 11 bilevel platform.
This is particularly useful for people who use bilevel therapy and want heated humidification and temperature control as part of their nightly setup.
ResMed’s product information identifies ClimateLineAir 11 heated tubing as compatible with Air11 devices, including AirSense 11 and AirCurve 11.
That means users of compatible AirCurve 11 bilevel machines can use the same Air11 heated tubing platform.
However, always verify your exact machine and accessory before ordering replacement equipment, particularly if your device is from an older ResMed generation.
AirSense 11 CPAP vs. AirCurve 11 Bilevel: What Does the Tubing Do?
The machines themselves are designed for different types of positive airway pressure therapy, but the ClimateLineAir 11 tubing serves the same basic purpose of carrying treated air between the machine and mask.
AirSense 11
The AirSense 11 family is designed for CPAP and related PAP therapy applications.
The ClimateLineAir 11 can be used as part of the humidification system to help manage the temperature and humidity of the delivered air.
AirCurve 11
AirCurve 11 devices are bilevel PAP machines. Depending on the model and prescription, bilevel therapy can use different pressure levels during inhalation and exhalation.
The tubing still provides the pathway between the device and mask.
The important point is that the tubing is not what determines whether therapy is CPAP or bilevel. Your PAP machine and prescribed therapy settings determine that.
The ClimateLineAir 11 is an accessory designed to support the delivery system.
How Does Heated CPAP Tubing Work?
The basic idea is straightforward.
Your PAP machine generates airflow. If a humidifier is being used, moisture is added to the air. That air then travels through the tubing to your mask.
When ordinary tubing is exposed to a cooler bedroom environment, the temperature of the air inside the tube can change.
If warm, humidified air encounters cooler tubing walls, condensation may form.
This is commonly called rainout.
You may notice:
- Water droplets inside the tube
- Moisture reaching the mask
- Gurgling sounds
- A wet feeling around the mask
- Unexpected water in the tubing
Heated tubing is designed to help manage this problem by maintaining a more consistent temperature along the air pathway.
The ClimateLineAir 11 is part of ResMed’s Climate Control system. When used with the compatible HumidAir 11 humidifier, it allows the Air11 system to manage temperature and humidity more effectively.
What Is CPAP Rainout?
CPAP rainout is condensation that forms when humidified air cools inside the tubing.
Imagine breathing warm air into a cold room. The temperature difference can cause moisture to collect.
The same basic concept can happen in CPAP tubing.
For example, you might have your humidifier producing warm, humid air. Your bedroom may be significantly cooler. As the humidified air moves through the tube, moisture can condense.
The result can be water inside the tubing.
Rainout is usually a comfort issue rather than an indication that your CPAP machine has stopped working.
Heated tubing can help reduce this type of condensation by keeping the air pathway warmer.
ResMed describes ClimateLineAir 11 as part of its Climate Control solution and says it is designed to help virtually eliminate rainout.
Why Use ClimateLineAir 11 With Humidification?
Humidification can be helpful for people who experience dryness during PAP therapy.
Some users report:
- Dry mouth
- Dry nose
- Nasal irritation
- Throat dryness
- A stuffy nose
Adding moisture to PAP airflow can make therapy feel more comfortable for some people.
However, too much humidity can create another problem: condensation.
That is why the humidifier and heated tubing work together.
The humidifier adds moisture.
The heated tubing helps maintain the temperature of the air as it travels toward the mask.
Together, these components are intended to create a more comfortable therapy environment.
Climate Control on AirSense 11
One of the useful features of the Air11 platform is its Climate Control system.
When compatible equipment is connected, the machine can manage humidification and tubing temperature as part of the overall system.
ResMed explains that Climate Control Auto is designed to automatically control temperature and humidity when the appropriate HumidAir 11 humidifier and ClimateLineAir 11 heated tube are being used.
For users, this can make the setup easier.
Instead of constantly changing settings and trying to guess what combination works best, the system can help regulate the environment automatically.
Users can also have different comfort preferences, and the AirSense 11 provides options for adjusting humidity and temperature.
If you experience dryness, excess moisture, or discomfort, speak with your healthcare provider or review your device’s instructions before making major therapy changes.
ClimateLineAir 11 Heated Tubing Features
The ClimateLineAir 11 is designed around the Air11 platform and has several features that make it different from standard CPAP tubing.
1. Heated tubing
The main feature is built-in heating technology.
This helps maintain the temperature of the air traveling through the tube.
2. Air11 compatibility
The tubing is designed for Air11 machines, including compatible AirSense 11 and AirCurve 11 devices.
3. Climate Control support
When paired with the appropriate humidification system, the tubing enables Climate Control functionality.
4. Flexible design
The tubing has a slim design intended to provide flexibility during sleep.
Flexible tubing can help reduce the feeling of being pulled by the hose when you change sleeping positions.
5. Condensation management
Maintaining temperature through the tube can help reduce condensation and rainout.
6. Easy connection
The tubing is designed to connect directly to the rear air outlet of compatible Air11 machines.
ClimateLineAir 11 Tubing Length
The ClimateLineAir 11 heated tube is approximately 6.5 feet long, with the manufacturer’s listed product specifications identifying a 2-meter tube length in some markets.
This length is intended to provide enough reach between your bedside PAP machine and your sleeping position without requiring an extension for typical setups.
Before purchasing an extension or alternate tube, consider your bedroom arrangement.
A tube that is excessively long may add unnecessary material around the bed, while a tube that is too short can restrict movement.
For most standard bedside setups, the intended ClimateLineAir 11 length is designed to provide practical reach.
How to Connect ClimateLineAir 11 to AirSense 11
Connecting the tubing is generally simple.
Before connecting it, make sure you understand which end belongs at the machine.
Step 1: Turn off or prepare the device
Follow your AirSense 11 instructions and make sure the device is safely prepared for connection.
Step 2: Find the rear air outlet
The air outlet is located at the back of the AirSense 11.
Step 3: Align the tubing
Hold the cuff of the ClimateLineAir 11 and line it up with the machine’s air outlet.
Step 4: Push it into place
Firmly connect the tubing to the outlet.
The electrical connector is designed for the machine side.
Step 5: Connect your mask
Attach the free end of the tubing to your assembled mask.
The electrical connector end should not be connected to the mask.
Step 6: Check the connection
The tubing should fit securely without being forced or twisted.
When connected correctly, the machine can recognize the ClimateLineAir tubing.
Always follow the manufacturer’s instructions for your exact device.
How to Connect ClimateLineAir 11 to AirCurve 11
The general connection process is similar for compatible AirCurve 11 devices.
The ClimateLineAir 11 connects to the device-side air outlet, while the other end connects to the mask tubing connection.
Make sure:
- The tubing is fully seated
- The electrical connector is connected to the machine
- The mask connection is secure
- The tubing is not sharply bent
- There are no visible cracks or tears
If the machine does not recognize the heated tube, disconnect and reconnect it carefully.
If the issue continues, consult the device manual or contact your equipment provider or ResMed support.
How to Clean ClimateLineAir 11 Heated Tubing
Cleaning your CPAP tubing is an important part of equipment care.
ResMed’s product guidance recommends regular cleaning of the ClimateLineAir 11 tubing.
A basic cleaning routine includes:
- Disconnect the tubing from the machine and mask.
- Wash the tubing in warm water with a small amount of household dishwashing liquid.
- Rinse thoroughly.
- Allow the tubing to dry completely.
- Keep it away from direct sunlight and excessive heat.
- Reconnect it once completely dry.
Do not place the ClimateLineAir 11 in a dishwasher or washing machine.
Avoid very hot water. ResMed’s product information specifies that the tubing should not be washed at temperatures above 131°F (55°C).
Why drying matters
Leaving moisture inside the tube can create an environment where unwanted buildup can occur.
After washing, allow the tube to drain and air-dry naturally.
Do not use a hair dryer or another high-heat source to speed up drying.
The heating components inside the tubing are designed for operation with the compatible PAP device, not for household drying methods.
How Often Should You Clean ClimateLineAir 11?
A regular cleaning schedule helps keep your CPAP setup fresh.
Many users make tubing cleaning part of their weekly equipment-care routine.
You should also inspect the tubing regularly.
Look for:
- Cracks
- Holes
- Tears
- Damaged cuffs
- Loose connections
- Unusual wear
- Moisture that does not clear normally
If the tubing is damaged, replacement is generally the safer option than attempting to repair it with tape, glue, or other household materials.
When Should You Replace ClimateLineAir 11 Tubing?
There is no single replacement date that applies to every user’s tubing condition.
Instead, inspect the tube regularly and replace it when it becomes damaged, excessively worn, or no longer functions properly.
Common reasons to replace the tube include:
Visible damage
If you see a hole, crack, or tear, replace the tubing.
Loose connection
A damaged cuff may not seal correctly.
Heating problems
If the tubing does not behave as expected with the compatible device, it may require replacement or professional troubleshooting.
Excessive wear
Repeated cleaning, handling, and daily use can eventually wear down equipment.
Persistent condensation
If you have ongoing rainout despite appropriate settings and equipment, review the setup with your provider.
Do not assume the tubing is defective without checking other possible causes.
Signs Your Heated Tubing May Need Attention
Sometimes the issue is not obvious.
You may notice:
- Increased condensation
- A change in normal airflow
- The machine does not recognize ClimateLine tubing
- The tube has visible damage
- The connection feels loose
- The tube looks unusually worn
- Your comfort has changed suddenly
Start with a visual inspection.
Check the connections at both ends.
Then review your machine settings and humidifier setup.
If the issue continues, contact your medical equipment provider or ResMed support.
ClimateLineAir 11 vs. Standard CPAP Tubing
Both types of tubing deliver air from a PAP machine to a mask, but their functions are different.
Standard tubing
Standard tubing provides an air pathway.
It does not have the same built-in heating function as ClimateLineAir 11.
ClimateLineAir 11
ClimateLineAir 11 provides the air pathway while adding heated-tube functionality designed for the Air11 Climate Control system.
This can be especially useful for users who experience condensation or want greater control over humidified air temperature.
Which one should you use?
If you have an AirSense 11 or compatible AirCurve 11 and want Climate Control functionality, ClimateLineAir 11 is the purpose-designed heated tubing option.
If you do not need heated tubing, your compatible machine may support standard tubing as well.
Your healthcare provider or equipment supplier can help you determine which setup is appropriate for your therapy.
ClimateLineAir 11 vs. Older ResMed ClimateLine Tubing
One common purchasing mistake is confusing tubing from different ResMed machine generations.
ResMed has produced heated tubing for multiple device platforms.
For example:
- ClimateLineAir 11 is designed for Air11 devices.
- Older ClimateLineAir tubing was designed for earlier Air10 systems.
- Other ResMed heated tubes were designed for different device generations.
The connector and electronic design matter.
If your machine is an AirSense 11 or AirCurve 11, look specifically for the Air11-compatible ClimateLineAir 11.
Do not select a replacement based only on the words “heated CPAP tube.”
Check the exact machine compatibility before purchasing.
Do AirSense 11 and AirCurve 11 Use the Same ClimateLineAir 11 Tubing?
For compatible Air11 models, ClimateLineAir 11 is used across the Air11 platform.
ResMed identifies the tubing as compatible with AirSense 11 and AirCurve 11 machines.
This means you do not generally need a separate “AirSense version” and “AirCurve version” of standard ClimateLineAir 11 tubing simply because one machine is CPAP and the other is bilevel.
The important consideration is whether the machine belongs to the compatible Air11 platform.
What About ClimateLineAir 11 Oxy?
There is another version called ClimateLineAir 11 Oxy.
This product is different from the standard ClimateLineAir 11.
The Oxy version includes an integrated oxygen connector designed for patients who require supplemental oxygen.
If you have been prescribed supplemental oxygen with PAP therapy, ask your healthcare provider whether an oxygen-compatible setup is appropriate.
Do not purchase or use an oxygen accessory simply because you think it may improve ordinary CPAP performance.
Supplemental oxygen should be used only according to your medical treatment plan.
If you do not need supplemental oxygen, the standard ClimateLineAir 11 may be the more relevant product to discuss with your equipment provider.
Does ClimateLineAir 11 Reduce Dry Mouth?
Heated tubing itself is not a treatment for dry mouth.
However, it is part of a humidification system that can help make PAP air more comfortable.
ResMed explains that humidification can help with common PAP side effects such as dry mouth and stuffy nose.
If you are experiencing persistent dry mouth, several factors may be involved.
These can include:
- Humidity settings
- Mouth breathing
- Mask type
- Mask leak
- Room temperature
- Nasal congestion
- Therapy settings
A heated tube can help with temperature and condensation control, but it does not automatically solve every cause of dry mouth.
If dryness continues, discuss it with your healthcare provider.
Can ClimateLineAir 11 Help With Rainout?
Yes, that is one of the main reasons people choose heated tubing.
The ClimateLineAir 11 is designed to help maintain a controlled temperature as humidified air travels through the tube.
This can reduce the likelihood of condensation forming inside the tubing.
However, no equipment setup can guarantee that condensation will never occur under every environmental condition.
Bedroom temperature, humidity, humidifier settings, mask type, and individual therapy conditions can all affect condensation.
If you continue to experience rainout, check the humidity and temperature settings according to your machine instructions.
How to Get More Comfortable With ClimateLineAir 11
Comfort is personal.
The setting that feels perfect to one person may not feel right to another.
If you are using ClimateLineAir 11 with your AirSense 11 or AirCurve 11, consider the following:
Keep the tube positioned comfortably
Avoid placing the tube under your body or allowing it to become tightly compressed.
Keep the tube away from sharp bends
A smooth path helps maintain proper airflow.
Keep the machine on a stable surface
This reduces the chance of pulling the machine or tubing when you move.
Review humidity settings
If your nose or mouth feels dry, humidity may need attention.
If you see excessive moisture, your settings or room conditions may need adjustment.
Give your equipment time
Small changes in sleep position, room temperature, and humidity can affect comfort.
If problems continue, ask your healthcare provider or equipment supplier for help.

ClimateLineAir 11 for Home CPAP Users
For someone using an AirSense 11 at home, the tubing can become one of those accessories you rarely think about until something goes wrong.
You may notice the difference when:
- Your tube becomes damaged
- You start seeing water inside the tubing
- Your machine no longer recognizes the heated tube
- Your replacement tubing does not fit
- Your current tubing becomes worn
Keeping a replacement plan can prevent a small equipment issue from becoming a major interruption to your nightly routine.
A good habit is to inspect your CPAP tubing when you clean your mask and other accessories.
It takes only a few moments.
ClimateLineAir 11 for AirCurve 11 Bilevel Users
Bilevel users also depend on reliable tubing for their nightly setup.
The AirCurve 11 platform uses positive airway pressure therapy, and the tubing carries that airflow between the device and mask.
ClimateLineAir 11 provides the additional heated-tubing function and works with the Air11 Climate Control system when paired with the appropriate humidifier.
Because bilevel therapy can involve different pressure settings than standard CPAP therapy, users should avoid making therapy changes independently.
The tubing is an accessory. It does not replace the need for professionally prescribed therapy settings.
A Simple Daily ClimateLineAir 11 Care Routine
Taking care of your CPAP equipment does not need to be complicated.
A simple routine can help you notice problems early.
Every day
Look briefly at the tubing.
Check for:
- Kinks
- Water
- Damage
- Loose connections
During regular cleaning
Disconnect the tubing and clean it according to the manufacturer’s instructions.
Allow it to dry completely before reconnecting it.
Periodically
Inspect the tube carefully from end to end.
If you see cracking, holes, tears, or significant wear, replace it.
When replacing
Make sure the new tubing is specifically compatible with your Air11 machine.
This small checklist can help prevent avoidable equipment problems.
Why the Right Tubing Matters
When you purchase CPAP supplies, it can be tempting to focus only on price.
But compatibility should come first.
A tube can look like it fits while still not providing the functions your machine expects.
The ClimateLineAir 11 heated tubing for AirSense 11 CPAP & AirCurve 11 bilevel machines is specifically designed around the Air11 platform.
That makes the model number important.
Before clicking “buy,” check your machine model and the manufacturer’s compatibility information.
This simple step can save time and reduce the frustration of receiving a replacement tube that does not work with your device.
Final Thoughts: ClimateLineAir 11 for Air11 Therapy
A comfortable PAP setup is built from several small pieces that work together.
The machine provides the prescribed therapy.
The humidifier adds moisture when used.
The mask creates the patient connection.
And the tubing carries the treated air between the device and mask.
The ClimateLineAir 11 heated tubing for AirSense 11 CPAP & AirCurve 11 bilevel machines is designed to make that connection more controlled by helping manage temperature and humidity along the air pathway.
For AirSense 11 and compatible AirCurve 11 users, it can be especially useful when condensation, cool airflow, or humidification comfort is a concern.
The most important thing is to choose the correct tubing for your machine, keep it clean, inspect it regularly, and replace it when it becomes damaged or worn.

If you use a ResMed AirSense 11 CPAP or AirCurve 11 bilevel machine, you may already know that the humidifier is an important part of the system. But what if you do not want to use the humidifier every night? What if you are traveling and want a simpler setup? Or what if your HumidAir water tub is temporarily unavailable?
This is where a side cover for AirSense 11 CPAP & AirCurve 11 bilevel machines can be useful.
The ResMed Air11 side cover is a replacement accessory designed to fit in the area normally occupied by the HumidAir 11 water tub. ResMed lists the Air11 side cover under part number 39226. It allows compatible Air11 therapy devices to operate without the HumidAir humidifier installed.
For many CPAP and bilevel users, the side cover is a small accessory that solves a simple problem. It can make a machine setup more convenient when humidification is not needed or when the user wants a more straightforward travel configuration.
At Alfa Healthcare Supply Inc., we understand that replacing a small CPAP component can sometimes feel confusing. You want to know whether you have the correct part, whether it fits your machine, and how it should be used. This guide explains those questions in simple language.
What is the Side Cover for AirSense 11 and AirCurve 11?
The side cover for AirSense 11 CPAP & AirCurve 11 bilevel machines is an accessory that covers the opening where the humidifier water chamber normally attaches.
ResMed describes the component as an Air11 side cover or end cap, with model/part number 39226.
Normally, an AirSense 11 or AirCurve 11 can be used with a HumidAir 11 water tub for heated humidification. When the humidifier is not being used, the side cover can be installed instead.

The cover provides a finished closure for that section of the machine and allows the compatible device to operate without the humidifier water chamber.
In simple terms:
Water tub installed = humidification setup
Side cover installed = non-humidified setup
This makes the side cover particularly useful for people who sometimes prefer humidification and sometimes do not.
Why Would Someone Need an AirSense 11 Side Cover?
Not every CPAP user needs heated humidification.
Some people are comfortable using their therapy without adding moisture to the airflow. Others may only use humidification during certain seasons. A person who travels frequently may also prefer a simpler setup.
ResMed specifically explains that the AirSense 11 side cover can replace the humidifier water tub and allow the device to operate without the humidifier.
There are several everyday situations in which this accessory may be useful.
1. You Do Not Want to Use the Humidifier
Some CPAP users find that they do not need added humidity.
If your healthcare professional has advised that your therapy can be used without humidification, the side cover provides a practical way to close the humidifier compartment.
2. You Are Traveling
Travel is one of the most common reasons people consider a side cover.
A water tub requires additional handling. You may need to empty it, dry it, protect it from spills, and pack it separately.
Using the side cover instead can create a simpler configuration when humidification is not required.
That does not mean every traveler should stop using humidification. Comfort needs are personal, and anyone who depends on humidification should consider their normal therapy routine before changing it.
3. Your Humidifier Tub Is Temporarily Unavailable
Sometimes a water chamber may be damaged, misplaced, or unavailable.
The side cover can provide an alternative for compatible Air11 machines when the humidifier is not being used.
4. You Want a Simpler Nightstand Setup
Some users prefer fewer components around their CPAP machine.
Without the water tub, there is no humidifier chamber to fill before bedtime. The setup can therefore feel more straightforward.
5. Seasonal Use
Some people prefer humidification during dry winter weather but do not use it during more humid months.
A side cover makes it easier to switch between configurations when appropriate.
Side Cover vs. HumidAir 11 Water Tub
The side cover and HumidAir 11 water tub serve different purposes.
The HumidAir 11 water tub is part of the humidification system. The side cover is used when the humidifier water tub is not installed.
Here is a simple comparison:
| Feature | Air11 Side Cover | HumidAir 11 Water Tub |
| Main purpose | Covers humidifier opening | Holds water for humidification |
| Water required | No | Yes, when humidification is used |
| Humidification | Not used | Available |
| Part number | 39226 | Various HumidAir 11 tub models |
| Useful for travel | Can simplify setup | Requires water-tub handling |
| Compatible system | Air11 devices | Air11 devices |
| Cleaning | Simple surface care | Requires water-tub cleaning |
The important point is that the side cover is not a humidifier replacement that provides moisture. Instead, it allows the machine to be used without the humidifier water tub.
ResMed’s product information states that an AirSense 11 device needs either the HumidAir 11 tub or the side cover fitted for operation.
Is the Side Cover Compatible With AirSense 11?
Yes. The ResMed Air11 side cover, part 39226, is designed for the AirSense 11 family.
ResMed’s accessory documentation lists the Air11 side cover as part number 39226.
AirSense 11 models include machines such as the AirSense 11 AutoSet and other AirSense 11 configurations.
However, it is always important to verify the exact machine model before ordering a replacement component.
Do not assume that a side cover designed for an older ResMed generation will fit an AirSense 11.
The Air11 platform uses its own accessories, and ResMed’s documentation distinguishes Air11 accessories from older Air10 accessories.
Is It Compatible With AirCurve 11 Bilevel Machines?
The side cover for AirSense 11 CPAP & AirCurve 11 bilevel machines is also associated with the AirCurve 11 family.
ResMed’s AirCurve 11 accessory ordering information lists the Air11 side cover, model 39226.
AirCurve 11 machines are bilevel therapy devices. ResMed describes AirCurve 11 devices as providing different pressure levels for inhalation and exhalation.
Although AirSense 11 and AirCurve 11 serve different therapy needs, they belong to the Air11 platform and share certain accessories.
This is why checking the model and accessory part number is important before purchasing.
ResMed Air11 Side Cover Part Number
One of the most important details to check when ordering is the part number.
ResMed Air11 Side Cover
Part Number: 39226
ResMed’s current accessories documentation identifies 39226 as the Air11 side cover/end cap.
ResMed’s AirCurve 11 product documentation also lists:
Air11 side cover — 39226
If you are replacing a missing or damaged cover, checking the part number can help reduce the chance of ordering the wrong accessory.
What Does the Air11 Side Cover Do?
The side cover has a straightforward purpose.
It covers the opening where the HumidAir water tub normally attaches.
When properly installed, it allows the compatible machine to operate without the humidifier water tub.
ResMed’s product description says the side cover can be used to replace a damaged cover or to operate an AirSense 11 without the humidifier.
This is especially useful because the machine should not simply be operated with an open humidifier compartment.
The correct cover provides the intended closure.
Does the Side Cover Turn Off the Humidifier?
Yes.
The side cover is designed for use when the humidifier is not being used. When it replaces the humidifier water tub, the humidification function is not available.
Third-party product documentation for the ResMed 39226 side cover describes the cover as automatically disabling the humidifier when installed.
Some product documentation also notes that heated humidification-related controls are unavailable when the side cover is installed.
If you want to use humidification again, you can switch back to the appropriate HumidAir water tub.
Does the Side Cover Work With Heated Tubing?
This is an important question.
The ClimateLineAir 11 heated tube is designed to work with Air11 devices, including AirSense 11 and AirCurve 11. ResMed confirms this compatibility on its current humidification and tubing page.
However, using a side cover means the humidifier is not operating.
Therefore, you should not expect the same humidification function that you receive when the HumidAir water tub is installed.
If you are using a ClimateLineAir 11 heated tube and changing from a humidified configuration to a non-humidified configuration, follow the machine’s user instructions and your healthcare provider’s guidance.
How to Install the AirSense 11 Side Cover
Installing the side cover is generally straightforward, but the machine should be handled carefully.
A simple process is:
Step 1: Turn Off the Machine
Before changing accessories, turn off your AirSense 11 or AirCurve 11.
For additional safety, follow the device manufacturer’s instructions for disconnecting the equipment from power when removing components.
Step 2: Remove the HumidAir Water Tub
If the water chamber is installed, remove it according to the machine’s instructions.
Do not force the water tub out.
Step 3: Check the Connection Area
Look at the opening where the humidifier tub was installed.
Make sure the area is clean and free from obvious debris.
Step 4: Position the Side Cover
Place the Air11 side cover into the appropriate opening.
The cover should fit correctly without excessive pressure.
Step 5: Make Sure It Is Secure
ResMed’s product information indicates that the side cover should click into place when inserted.
Do not operate the machine if the cover is loose, damaged, or improperly fitted.
Step 6: Check the Machine
Once the side cover is properly installed, check the machine before beginning therapy.
If the device displays an error or does not function normally, stop and consult the appropriate user guide or healthcare provider/service provider.
How Do I Remove the Side Cover?
Removing the side cover is generally the reverse of installation.
First, turn the machine off.
Then carefully remove the side cover according to the device instructions.
Avoid pulling aggressively or using tools to pry the cover loose.
After removal, the appropriate HumidAir 11 water tub can be installed if humidification is needed and appropriate for your therapy.
Always make sure the replacement component is properly seated before operating the machine.
Can I Use AirSense 11 Without Water?
Yes, the AirSense 11 can be configured to operate without the HumidAir water tub when the appropriate side cover is installed.
This does not mean that every person should stop using humidification.
Some people experience dryness, nasal irritation, congestion, or discomfort when using PAP therapy without humidification. ResMed notes that dry mouth and stuffy nose can be common CPAP side effects and offers humidification accessories to help make airflow more comfortable.
If you are comfortable without humidification, your clinician may consider that configuration appropriate.
If removing humidification makes therapy uncomfortable, talk with your healthcare professional about your options.
Can You Use the AirCurve 11 Without the Humidifier?
The AirCurve 11 platform also supports the Air11 side cover accessory.
ResMed lists 39226 as the Air11 side cover in its AirCurve 11 accessory information.
The basic concept is the same:
HumidAir tub installed → humidifier configuration
Air11 side cover installed → no humidifier water tub
If you use an AirCurve 11 bilevel machine and are considering changing how you use humidification, speak with your healthcare provider if you are unsure whether the change is appropriate for your therapy.
Is the Side Cover Useful for Travel?
For some people, yes.
Travel can make CPAP therapy feel more complicated than it needs to be.
A water chamber adds another component to pack. You may also need to think about emptying and drying the chamber before putting your equipment into a travel bag.
If you normally sleep comfortably without humidification, an Air11 side cover can create a simpler configuration.
It can also help avoid carrying water for the humidifier.
However, if humidification is important to your comfort or therapy routine, do not remove it simply to make packing easier.
Good CPAP travel equipment is ultimately about maintaining a setup that you can use comfortably and consistently.
What If My Side Cover Is Lost?
A lost side cover is not something you should ignore.
If you remove the HumidAir water tub, the machine should have the correct side cover installed rather than being left open.
The AirSense 11 side cover is specifically designed for this purpose. ResMed states that an AirSense 11 will not work unless it is fitted with either the HumidAir 11 water tub or the side cover.
If your cover is missing, look for the correct Air11 replacement part.
When ordering, verify:
- Manufacturer
- Machine model
- Air11 generation
- Part number
- Compatibility
- Condition of the replacement part
The ResMed part number to look for is 39226.
What If My Side Cover Is Cracked?
A cracked side cover should be replaced if it no longer fits securely.
Do not try to repair a damaged cover with household glue, tape, or another improvised method.
A replacement accessory is a better approach because the cover is designed specifically for the machine.
Before ordering, compare the replacement part with your machine and confirm compatibility.
If you are unsure, ask your DME supplier or healthcare equipment provider to verify the correct part.
Side Cover vs. Air Outlet: Do Not Confuse Them
The Air11 side cover and air outlet are different components.
ResMed’s current accessories guide lists both:
- Air11 side cover — 39226
- Air11 air outlet — 39220
The side cover closes the humidifier area.
The air outlet is part of the airflow connection system.
Because these components have different functions, they should not be substituted for each other.
When shopping for replacement parts, always check the product name and part number.
Side Cover vs. Filter Door
The filter door is another separate component.
ResMed’s AirCurve 11 documentation lists the filter door replacement separately from the Air11 side cover.
This distinction matters because people sometimes use general terms such as “side panel,” “cover,” or “door” when describing CPAP parts.
If you need the humidifier opening covered, you are looking for the Air11 side cover, not the filter door.
Side Cover vs. SD Card Door
The SD card door is also a different component.
ResMed lists an AirCurve 11 SD card door separately in its accessory documentation.
So if the SD card compartment is damaged, ordering an Air11 side cover would not solve the problem.
When purchasing replacement parts, use the exact component name whenever possible.
How to Keep the Side Cover Clean
The side cover does not hold water, so its maintenance is generally simpler than maintaining a humidifier water tub.
For routine care:
- Remove the cover according to the device instructions.
- Inspect it for dust or visible debris.
- Clean it using the manufacturer’s recommended method.
- Allow it to dry completely if it has been washed.
- Inspect for cracks or damage.
- Reinstall it securely.
Avoid harsh chemicals unless the manufacturer specifically recommends them.
Also avoid excessive heat that could deform the plastic.
When in doubt, follow the current ResMed user guide for your specific device.
Does the Side Cover Need Regular Replacement?
Not necessarily.
A side cover is generally a replacement component rather than a disposable consumable.
You may need a new one if the existing cover becomes:
- Lost
- Cracked
- Broken
- Damaged
- Loose
- Difficult to install correctly
There is no reason to replace a properly functioning cover simply because you have had it for a certain number of months.
Instead, inspect it periodically and replace it when necessary.
Signs You May Need a New Side Cover
Look at your existing cover if you notice:
Cracks
A visible crack can affect the fit and durability of the component.
Broken Clips
If the retaining mechanism is damaged, the cover may not stay securely attached.
Loose Fit
A properly installed cover should fit correctly. If it repeatedly comes loose, investigate the cause.
Missing Cover
If you cannot find your side cover, obtain the appropriate replacement before using the machine without the water tub.
Visible Damage
Damage from dropping or mishandling the machine may affect the cover.
If you are uncertain whether a damaged part is safe to use, contact your equipment provider.
Does the Side Cover Make the Machine Smaller?
Replacing the humidifier water tub with the side cover can make the overall setup more streamlined.
It eliminates the water chamber from the configuration, which can be useful for travel and storage.
However, the amount of space saved will depend on how you pack the machine and what other accessories you carry.
The main advantage is not necessarily a dramatic reduction in size. It is the removal of the humidifier chamber and the need to manage water.
Can the Side Cover Help Reduce Water Handling?
Yes.
When you use the side cover instead of the HumidAir water tub, there is no humidifier chamber to fill with water.
That can be convenient for:
- Travel
- Short trips
- Overnight stays
- Work travel
- Hotel stays
- Backup setups
Again, this is appropriate only when using the machine without humidification is suitable for you.
What About Dry Mouth or Dry Nose?
This is one of the most important comfort considerations.
Humidification can help some CPAP users who experience dryness.
ResMed explains that dry mouth and a stuffy nose are common CPAP side effects and that humidification can help provide warm, moist airflow.
If you install the side cover and begin experiencing significant dryness, nasal irritation, or discomfort, consider discussing the issue with your healthcare provider.
Do not assume that discomfort means your CPAP pressure needs to be changed.
Pressure settings should be managed by an appropriately qualified healthcare professional.
Is the Air11 Side Cover a Medical Device?
The side cover is an accessory/replacement component for the ResMed Air11 therapy platform.
It does not independently provide CPAP or bilevel therapy.
Its function is mechanical: it closes the humidifier opening when the water tub is not installed.
Your AirSense 11 or AirCurve 11 machine remains the therapy device.
Does the Side Cover Change CPAP Pressure?
The side cover is not designed to adjust your prescribed therapy pressure.
It does not function as a pressure-control accessory.
Your prescribed settings remain controlled by the therapy machine.
If you believe your pressure is too high or too low, speak with your sleep specialist or healthcare provider rather than attempting to change settings because you installed a side cover.
Who May Want an Air11 Side Cover?
The accessory may be useful for people who:
- Use an AirSense 11 system without humidification
- Use an AirCurve 11 system without humidification
- Travel frequently
- Want a simpler CPAP setup
- Need a replacement for a lost side cover
- Need to replace a damaged side cover
- Want an alternative to carrying the HumidAir water chamber
It is not necessary for every user.
The best configuration depends on your therapy requirements and comfort.
What Should You Check Before Buying?
Before ordering a side cover for AirSense 11 CPAP & AirCurve 11 bilevel machines, take a moment to verify the following.
Check 1: Your Machine
Confirm that you have an AirSense 11 or compatible AirCurve 11 device.
Check 2: The Part Number
Look for 39226 for the Air11 side cover.
ResMed documentation identifies 39226 as the Air11 side cover.
Check 3: Product Description
Make sure the product description specifically identifies the component as the Air11 side cover/end cap.
Check 4: Compatibility
Confirm that the seller lists your exact Air11 machine family.
Check 5: Condition
If purchasing a replacement, determine whether it is new, genuine, or otherwise appropriate for your equipment.
Why Genuine Compatibility Matters
CPAP machines are medical therapy equipment.
A small plastic component may look simple, but the correct fit matters.
Using a component designed for another ResMed generation may result in poor fit or incompatibility.
ResMed’s current documentation identifies the Air11 side cover specifically as part 39226.
For this reason, checking the manufacturer’s part number is one of the simplest ways to reduce ordering mistakes.
AirSense 11 and AirCurve 11: What’s the Difference?
It is useful to understand the difference between the machines even though they share certain accessories.
AirSense 11
AirSense 11 systems are designed for CPAP/APAP therapy. ResMed describes AirSense 11 as a platform combining CPAP/APAP therapy modes with digital health features.
AirCurve 11
AirCurve 11 devices are bilevel systems. ResMed describes the platform as providing separate pressure levels for inhalation and exhalation.
The therapy technology differs, but the Air11 side cover is listed as an accessory for the Air11 platform.
Can I Keep the Humidifier for Some Nights and Use the Side Cover on Other Nights?
In many situations, yes.
That is one of the practical reasons to have a side cover.
You can use the HumidAir water tub when you want humidification and install the side cover when you are using the machine without the humidifier.
The key is to make sure the correct component is properly installed each time.
Do not operate the machine with the humidifier opening improperly configured.
Side Cover and CPAP Travel: A Practical Example
Imagine you are traveling for two nights.
At home, you normally use your AirSense 11 with humidification. Your hotel room, however, has limited space around the bedside table.
If you are comfortable using your prescribed therapy without humidification, the side cover may allow you to leave the water tub at home.
You can pack:
- AirSense 11 machine
- Side cover
- CPAP tubing
- Mask
- Power supply
- Required accessories
There is no humidifier chamber to fill, empty, or dry.
This can make packing easier.
But if you know you sleep poorly without humidification, bringing the water tub may be the better choice for your personal comfort.
Is It a Good Idea to Keep a Spare Side Cover?
For frequent travelers, keeping a spare can be convenient.
A side cover is small compared with many other CPAP components.
A spare may be useful if your primary cover is lost during travel.
However, you should still keep your CPAP equipment organized and protected.
Labeling your spare accessories can also make it easier to identify the correct component.
Common Mistakes to Avoid
Mistake 1: Buying an Air10 Side Cover
Air10 and Air11 are different generations.
Do not assume that an Air10 accessory will fit an Air11 machine.
Mistake 2: Confusing the Side Cover With the Filter Door
They are separate components.
Mistake 3: Operating With the Opening Uncovered
If the humidifier tub is removed, use the appropriate side cover.
Mistake 4: Forcing the Cover
A correctly matched cover should fit the intended opening. If it does not, stop and verify the part.
Mistake 5: Ignoring Comfort Changes
If you switch from humidification to a non-humidified setup and experience significant dryness or irritation, talk with your healthcare provider.
Mistake 6: Changing Therapy Settings Yourself
The side cover is not a reason to change pressure settings.
Buying a Side Cover From Alfa Healthcare Supply Inc.

Why Correct CPAP Replacement Parts Matter
CPAP therapy is something many people use every night.
That means small replacement parts can become surprisingly important.
A missing side cover may not seem like a major issue when compared with the machine itself. But if you want to operate the machine without the humidifier, the correct cover is part of the intended setup.
The same principle applies to:
- CPAP tubing
- Mask cushions
- Filters
- Water chambers
- Air outlets
- SD card doors
- Power supplies
- Replacement cushions
Using the correct component helps keep your equipment setup organized and compatible.

This guide explains what the Air 11 air outlet is, what it does, how it relates to AirSense 11 and AirCurve 11 machines, signs that it may need replacement, installation considerations, cleaning, compatibility, troubleshooting, and common questions.
Important: This article is for general equipment information and does not replace the instructions supplied with your ResMed device or advice from your healthcare professional or medical equipment provider.
What is a ResMed Air Outlet Adapter?
The term ResMed air outlet adapter is commonly used when people are looking for the component that provides the air connection at the rear of an Air 11 machine.
In ResMed documentation, the replacement component is identified as the Air 11 Air outlet, with model number 39220 in the AirCurve 11 accessory ordering information.
The air outlet is located at the rear of the machine. Air tubing attaches to this outlet so that therapy air can travel from the device toward the mask.

ResMed’s AirSense 11 user guide specifically instructs users to connect the air tubing firmly to the outlet connector at the rear of the device. The AirCurve 11 user guide provides the same basic connection instruction.
In simple words, think of the air outlet as an important connection point between your PAP machine and your tubing.
It is not the same thing as:
- A CPAP mask
- A complete air hose
- A humidifier water tub
- A mask elbow
- A standard tubing connector
- A power adapter
- A filter
- A side cover
These components may all be part of a larger CPAP setup, but they serve different purposes.
Why the Air Outlet Matters
A CPAP or bilevel machine needs a reliable path for air to travel from the device to the patient.
For an AirSense 11 or AirCurve 11, that pathway begins at the machine and continues through the air tubing before reaching the mask.
The air outlet therefore needs to provide a secure connection.
If the outlet or its connection area is damaged, the tubing may not sit correctly. A poor connection can make the equipment difficult to use and may contribute to unwanted air leakage.
That is why replacing a damaged outlet is more than a cosmetic repair.
A properly fitted replacement part can help restore the physical connection between the machine and tubing.
ResMed’s user documentation emphasizes that the air tubing should be connected firmly to the outlet connector at the rear of the device.
ResMed Air Outlet for AirSense 11 and AirCurve 11
The AirSense 11 and AirCurve 11 are both part of ResMed’s Air11 platform.
The AirSense 11 is designed as a CPAP/APAP platform, while AirCurve 11 devices provide bilevel therapy. ResMed describes AirCurve 11 as a bilevel platform with different pressure levels for inhalation and exhalation.
Despite their different therapy functions, both devices use a rear air outlet connection for their tubing.
ResMed’s AirCurve 11 accessory ordering information lists:
Air 11 Air outlet — Model 39220
The same guide also lists other Air11 replacement components, including the Air11 side cover, filter door, power supply, tubing, and humidifier tubs.
This distinction is important when shopping for a replacement.
If you search online for a phrase such as “AirSense 11 air outlet adapter,” you may see several different descriptions. Some sellers may call the component an air outlet, outlet adapter, tubing connector, or replacement outlet.
Before purchasing, compare the part with your machine and verify compatibility.
What Does the Air Outlet Do?
The air outlet has a simple but important job.
It provides the machine-side connection for the air tubing.
The basic airflow path can be understood like this:
PAP machine → Air outlet → Air tubing → Mask → Patient
When everything is properly connected, therapy air can move through the system as intended.
The outlet must therefore be positioned correctly and provide a secure connection for the tubing.
A damaged outlet can create practical problems such as:
- Difficulty attaching the tubing
- Tubing that does not stay securely connected
- Visible damage around the outlet
- Unusual looseness at the machine connection
- Difficulty removing or attaching the tubing
- Air escaping around a damaged connection
- A replacement tubing connection that does not fit correctly
Not every problem involving airflow is caused by the air outlet, however.
A worn mask cushion, damaged tubing, loose connection elsewhere, incorrect equipment assembly, or other issue can also contribute to air leakage or therapy problems.
Air Outlet vs. Air Tubing: What’s the Difference?
This is one of the most common points of confusion.
The air outlet is the connection component on the machine.
The air tubing is the hose that carries air from the machine to the mask.
For example, ResMed lists the ClimateLineAir 11 heated tubing as an Air11 accessory and states that ClimateLineAir 11 heated tubing is compatible with Air11 devices including AirSense 11 and AirCurve 11.
So if your tubing is cracked or worn, you may need replacement tubing.
If the machine-side outlet itself is damaged, replacing the tubing alone may not solve the problem.
Before ordering a replacement, identify which component is actually damaged.
Signs You May Need a Replacement Air Outlet
The following signs may indicate that the air outlet should be inspected:
1. The Tubing Does Not Connect Properly
If your tubing suddenly becomes difficult to attach to the machine, check the outlet and tubing connection.
Do not force the tubing into place.
Forcing a connection can potentially damage the component further.
2. The Outlet Appears Cracked
Visible cracking is a clear reason to stop and inspect the component carefully.
A cracked plastic connection may not provide the secure fit required for normal use.
3. The Connection Feels Unusually Loose
A little movement may occur depending on the design of the connection, but a connection that feels substantially different from normal should be inspected.
Check both the tubing and machine outlet.
4. You Notice Air Escaping Near the Machine Connection
Air escaping near the machine-side connection may indicate a problem with:
- The air outlet
- Tubing
- Tubing connector
- A damaged seal
- Incorrect assembly
Do not automatically assume the air outlet is the cause.
Inspect the entire connection.
5. The Outlet Has Been Damaged During Handling
CPAP machines can be moved, packed for travel, or accidentally bumped.
If the outlet area has been damaged, inspect it before continuing regular use.
How to Check the Air Outlet
Before ordering a replacement, take a few minutes to inspect the area.
Step 1: Turn the Device Off
Turn off your PAP machine before disconnecting equipment.
Step 2: Disconnect the Tubing
Remove the air tubing carefully from the machine.
Step 3: Examine the Outlet
Look for:
- Cracks
- Broken plastic
- Deformation
- Unusual movement
- Dirt or debris
- Signs of physical damage
Step 4: Check the Tubing
Look at the tubing connector as well.
Sometimes the tubing itself is the problem.
Step 5: Confirm Your Machine
Check the label or device information to make sure you have an AirSense 11 or AirCurve 11 model.
Step 6: Verify the Replacement Part
If you are purchasing an Air11 air outlet, compare the manufacturer’s part information with the replacement you are considering.
ResMed’s AirCurve 11 product guide identifies the Air 11 Air outlet as model 39220.
Is the Air Outlet Compatible With AirSense 11?
The Air 11 air outlet is associated with the Air11 platform.
ResMed’s documentation identifies the Air 11 Air outlet as model 39220, and AirSense 11 and AirCurve 11 are both part of the Air11 family.
However, compatibility should always be confirmed before purchase.
Do not assume that an air outlet designed for an older AirSense 10 or AirCurve 10 is automatically interchangeable with an AirSense 11 or AirCurve 11.
ResMed specifically distinguishes Air10 and Air11 accessories in its documentation.
For example, ResMed states that ClimateLineAir and ClimateLineAir Oxy tubing for Air10 devices are compatible with AirSense 10 and AirCurve 10, while ClimateLineAir 11 tubing is compatible with Air11 devices.
This is a good reminder:
AirSense 10 is not the same platform as AirSense 11.
Always verify the machine generation before ordering replacement parts.
Is the Air Outlet Compatible With AirCurve 11?
The AirCurve 11 platform also uses an air outlet at the rear of the device.
ResMed’s AirCurve 11 user guide instructs users to connect the air tubing firmly to the outlet connector at the rear of the device.
ResMed’s AirCurve 11 accessory information lists the Air 11 Air outlet, model 39220.
Therefore, when searching for a replacement for an AirCurve 11, it is important to search by the Air11 platform and verify the specific replacement part.
AirSense 11 CPAP and AirCurve 11 Bilevel: What’s the Difference?
Understanding the machines can make replacement-part shopping easier.
AirSense 11
ResMed describes the AirSense 11 as a CPAP/APAP device platform designed to support sleep apnea therapy.
Depending on the model and prescribed setup, the machine can deliver continuous or automatically adjusted positive airway pressure.
AirCurve 11
AirCurve 11 devices are bilevel machines.
ResMed explains that bilevel therapy uses different pressure levels for inhalation and exhalation.
AirCurve 11 models include versions such as AirCurve 11 VAuto and AirCurve 11 ASV, with therapy intended for different clinical needs.
Even though the therapy modes are different, both systems use an air outlet connection at the back of the machine.
Why Correct Fit Matters
CPAP equipment works as a connected system.
The machine, air outlet, tubing, mask, humidification system, and other accessories all need to work together.
A replacement part that looks similar may not necessarily be the correct part.
An incorrect component can result in:
- Poor physical fit
- Loose connections
- Difficulty attaching tubing
- Potential air leakage
- Damage to equipment
- Difficulty maintaining your normal setup
That is why checking the model number and manufacturer information is important.
When purchasing replacement parts from a medical supply provider, have your machine model available whenever possible.
Air Outlet and ClimateLineAir 11 Heated Tubing
Many AirSense 11 and AirCurve 11 users use heated tubing.
ResMed’s ClimateLineAir 11 heated tubing is designed for Air11 devices, including AirSense 11 and AirCurve 11.
The heated tubing has an electrical connector on the machine side.
ResMed specifically warns that the electrical connector end of the heated air tubing is intended for the device-end air outlet and should not be connected to the mask.
This is an important detail.
If you use ClimateLineAir 11 tubing, do not treat it like ordinary tubing. Follow the manufacturer’s connection instructions.
Air Outlet and Standard SlimLine Tubing
Air11 systems can also use compatible standard tubing.
ResMed’s AirCurve 11 product guide lists SlimLine tubing as an Air11 accessory.
Whether you use heated or standard tubing depends on your equipment setup and therapy needs.
If you are replacing an air outlet, identify your tubing type before ordering.
This helps ensure that the replacement component and your existing equipment work together correctly.
How to Replace a ResMed Air Outlet
Replacement of a machine component is different from simply changing a CPAP mask cushion or tubing.
If the air outlet itself needs replacement, users should follow the manufacturer’s instructions and consider having the component replaced by a qualified medical equipment provider or technician when appropriate.
A general process may include:
- Turn the machine off.
- Disconnect it from electrical power.
- Remove the air tubing.
- Inspect the outlet and surrounding components.
- Verify the correct replacement part.
- Install the replacement according to applicable ResMed instructions.
- Reconnect the tubing.
- Check the connection before therapy.
- Confirm that the equipment operates normally.
Do not attempt to repair a damaged component with glue, tape, household sealant, or another improvised material.
A PAP machine is medical equipment, and improvised repairs may affect the equipment’s safe operation.
Do Not Force the Air Tubing
One simple rule can prevent unnecessary damage:
Never force the tubing connection.
If the tubing will not attach easily:
- Stop
- Check the outlet
- Check the tubing connector
- Confirm that you have the correct tubing
- Look for damage or debris
If something does not fit, forcing it is rarely the right solution.
This is particularly important with heated tubing because the machine-side connector includes electrical components.
ResMed’s AirSense 11 instructions specifically explain that the electrical connector end of heated tubing is designed for the device-side air outlet.
Cleaning Around the Air Outlet
The air outlet should be kept clean as part of normal equipment care.
However, avoid using harsh cleaning products or soaking machine components unless the manufacturer’s instructions specifically allow it.
A safe approach is to follow the cleaning instructions supplied with your exact ResMed machine.
The goal is to keep the connection area free from unnecessary dust, debris, and residue without damaging the machine.
Remember that cleaning the air outlet is different from cleaning the air tubing.
Your tubing may have its own cleaning instructions.
What If the Air Outlet Is Dirty?
If you notice dust or debris around the outlet, first turn the machine off and disconnect the equipment.
Inspect the area carefully.
Do not push objects into the outlet.
Do not use sharp tools to scrape the connection.
Do not spray liquid directly into the machine.
If you are unsure how to clean a particular component, consult the ResMed user guide or contact your equipment provider.
What If the Air Outlet Is Loose?
A loose outlet should not simply be ignored.
First determine whether:
- The tubing connector is loose
- The tubing is worn
- The outlet itself has movement
- The outlet has visible damage
- Another component has become displaced
If the outlet itself appears loose or damaged, stop forcing the connection and seek assistance from your medical equipment supplier or qualified service provider.
A replacement component may be appropriate, but the exact cause should be identified first.
What If I Hear Air Leaking?
Air leakage can come from several locations.
Possible sources include:
Mask leak
The mask cushion may not be sealing correctly.
Tubing leak
The tubing may have a hole, crack, or damaged connector.
Machine connection
The air outlet or tubing connection may not be secure.
Humidifier connection
The humidifier assembly may not be seated correctly.
Mask connection
The tubing may not be properly connected to the mask.
Because there are several possibilities, do not immediately purchase a replacement air outlet simply because you hear air.
Inspect the complete airflow path.
If you continue experiencing therapy problems, contact your healthcare professional or PAP equipment provider.
Can I Use an AirSense 10 Air Outlet on an AirSense 11?
Do not assume that an AirSense 10 replacement outlet is interchangeable with an AirSense 11 component.
The AirSense 10 and AirSense 11 are different generations.
ResMed’s accessory information distinguishes Air11 components from Air10 components. Its tubing information likewise separates Air11-compatible ClimateLineAir 11 tubing from Air10-compatible ClimateLineAir tubing.
For an AirSense 11, look specifically for the appropriate Air11 component.
For an AirCurve 11, verify the Air11 compatibility as well.
Can I Use the Same Air Outlet for AirSense 11 and AirCurve 11?
The Air11 platform includes both AirSense 11 and AirCurve 11 devices, and ResMed’s AirCurve 11 accessory information lists the Air 11 Air outlet under model 39220.
Still, it is good practice to confirm the exact machine model and part compatibility before ordering.
Medical equipment can have different configurations, and product listings can sometimes use confusing terminology.
When in doubt, provide your equipment supplier with:
- Machine name
- Machine model
- Part name
- Existing part information
- A photo of the damaged component, if requested
This can make identification easier.
ResMed Air Outlet Adapter vs. Air Outlet Connector
Online product descriptions may use different names for similar components.
You may encounter terms such as:
- ResMed Air 11 Air outlet
- AirSense 11 air outlet
- AirCurve 11 air outlet
- Air outlet adapter
- Air outlet connector
- Replacement air outlet
- CPAP machine air outlet
The terminology can vary between sellers.
The most important thing is the actual part and compatibility, not simply the wording in the product title.
For ResMed’s AirCurve 11 documentation, the replacement component is specifically listed as Air 11 Air outlet, model 39220.
Why Buy Replacement CPAP Parts From a Medical Supply Store?
Shopping for a small CPAP component online can feel surprisingly complicated.
There are many listings, different model numbers, aftermarket parts, older components, and similar-looking accessories.
A medical supply provider can help make the process more straightforward by helping you identify the equipment and replacement component.
At Alfa Healthcare Supply Inc., our goal is to make medical equipment shopping easier for patients and caregivers.
We understand that people may be replacing a part because something has worn out, broken, become difficult to use, or simply needs routine replacement.
The right information can save time and help avoid ordering the wrong part.
You can explore available medical equipment and supplies through the Alfa Healthcare Supply website.
How to Choose the Right ResMed Air Outlet
Before purchasing, use this simple checklist.
1. Identify the Machine
Is your device:
- ResMed AirSense 11?
- ResMed AirCurve 11?
- Another ResMed model?
Do not rely only on memory.
Look at the machine itself.
2. Confirm the Platform
Air11 components are designed for the Air11 platform.
Avoid assuming that older Air10 components will fit.
3. Check the Part Number
For the Air 11 Air outlet, ResMed’s AirCurve 11 product guide lists model 39220.
4. Check the Existing Tubing
Know whether you use:
- ClimateLineAir 11 heated tubing
- ClimateLineAir 11 Oxy heated tubing
- SlimLine tubing
- Another compatible tubing configuration
ResMed confirms that ClimateLineAir 11 and ClimateLineAir 11 Oxy tubing are designed for Air11 devices including AirSense 11 and AirCurve 11.
5. Ask Before Ordering If You Are Unsure
A few minutes of verification can be much easier than receiving an incompatible component.
Air Outlet Replacement for Caregivers
Caregivers often handle CPAP equipment for family members.
If you are purchasing a replacement for someone else, take a photo of the machine label or write down the exact model before ordering.
This is especially helpful when the patient has more than one piece of respiratory equipment at home.
For example, an AirSense 11 and an AirCurve 11 may look similar from a distance, while their therapy functions are different.
Having the exact model information helps reduce confusion.
Traveling With an AirSense 11 or AirCurve 11
Travel can place additional stress on CPAP equipment.
When packing your machine:
- Disconnect tubing carefully.
- Protect the machine from impact.
- Avoid placing heavy items on the device.
- Keep small replacement components together.
- Protect the air outlet from unnecessary force.
- Use an appropriate equipment bag when available.
If the air outlet is damaged while traveling, do not improvise a permanent repair with tape or glue.
Instead, inspect the equipment and contact your supplier or service provider for the appropriate replacement solution.
Why Small CPAP Parts Deserve Attention
It is easy to focus on the big pieces of a CPAP setup:
- The machine
- The mask
- The humidifier
- The tubing
But small components can be equally important.
A connector that does not fit properly can make the entire setup frustrating.
For someone who uses PAP therapy every night, these little problems can become very noticeable.
A properly identified replacement part can help restore confidence in the equipment setup.
That is why knowing the difference between an air outlet, tubing, mask connector, filter door, and side cover is useful.
Air Outlet and Humidification
The AirSense 11 and AirCurve 11 platforms include integrated humidification options.
ResMed states that HumidAir 11 is built into Air11 devices, including AirSense 11 and AirCurve 11, and that ClimateLineAir 11 heated tubing can work with the device’s humidification system.
The air outlet is still the machine-side connection for the air tubing.
It does not replace the humidifier tub or heating system.
If your concern is dryness, condensation, or humidity, replacing the air outlet may not address the underlying issue.
Those concerns should be evaluated separately.
Understanding Airflow Problems
If therapy airflow seems different after replacing or reconnecting a component, check the entire setup.
Start with the basics:
- Is the machine powered on?
- Is the tubing connected firmly?
- Is the tubing damaged?
- Is the mask connected properly?
- Is the humidifier seated correctly?
- Is the air outlet intact?
- Are there any visible cracks or disconnected components?
If the equipment still does not work normally, consult your equipment provider.
Do not change prescribed pressure or therapy settings simply because a mechanical connection is not working correctly.
Air Outlet Maintenance Tips
A few simple habits can help protect your CPAP equipment.
Handle tubing gently
Avoid pulling the tubing sharply from the machine.
Disconnect by the connector
When removing tubing, handle the connector rather than aggressively pulling on the hose.
Keep the machine stable
Place the device on a stable, level surface.
ResMed’s AirSense 11 and AirCurve 11 setup instructions both begin with placing the device on a stable, level surface.
Inspect equipment regularly
Look for cracks, discoloration, loose connections, and unusual wear.
Replace damaged components
Do not continue using a visibly damaged connection simply because the machine still turns on.
Common Mistakes When Buying an Air Outlet
Mistake 1: Buying by Appearance
Two components may look similar but belong to different device generations.
Mistake 2: Ignoring the Model Number
Always verify whether you have an AirSense 11, AirCurve 11, or another device.
Mistake 3: Confusing the Outlet With the Tubing
The air outlet and tubing are separate components.
Mistake 4: Assuming AirSense 10 Parts Fit AirSense 11
Do not assume compatibility across generations.
Mistake 5: Using Improvised Repairs
Tape, glue, and household adapters are not substitutes for a proper medical equipment component.
Mistake 6: Ignoring a Damaged Connection
A cracked or loose outlet should be inspected rather than repeatedly forced into use.
Frequently Asked Questions
What is a ResMed Air 11 air outlet?
The Air 11 air outlet is the machine-side outlet where compatible air tubing connects. ResMed’s AirCurve 11 product guide identifies the Air 11 Air outlet as model 39220.
Is the Air 11 air outlet used with AirSense 11?
The AirSense 11 uses a rear outlet connector for its air tubing. ResMed’s AirSense 11 user guide instructs users to connect the tubing firmly to this rear outlet.
Always verify the replacement component before purchasing.
Is the Air 11 air outlet used with AirCurve 11?
AirCurve 11 devices also have a rear outlet connector for air tubing. ResMed’s AirCurve 11 accessory guide lists the Air 11 Air outlet as model 39220.
What is the ResMed Air 11 Air outlet model number?
ResMed lists the Air 11 Air outlet as model 39220 in the AirCurve 11 product guide.
Is an air outlet the same as CPAP tubing?
No. The air outlet is the connection component on the machine. CPAP tubing is the hose that carries air from the machine to the mask.
Can I use ClimateLineAir 11 tubing with AirSense 11?
ResMed states that ClimateLineAir 11 heated tubing is compatible with Air11 devices, including AirSense 11 and AirCurve 11.
Can I use ClimateLineAir 11 tubing with AirCurve 11?
Yes. ResMed lists ClimateLineAir 11 heated tubing as compatible with Air11 devices, including AirCurve 11.
What should I do if my air tubing will not connect?
Do not force it. Check the tubing connector, air outlet, and equipment model. If the connection remains incorrect or damaged, contact your medical equipment provider.
What if the air outlet is cracked?
A cracked air outlet should be inspected and replaced with the appropriate compatible component rather than repaired with household materials.
Can I glue a broken CPAP air outlet?
Improvised repairs such as glue are not recommended for a medical equipment connection. Contact your equipment supplier or qualified service provider for the correct replacement procedure.
Why is air leaking near my CPAP machine?
Possible causes include damaged tubing, an improperly connected tube, a damaged outlet, or another connection issue. Inspect the complete system rather than assuming the outlet is automatically responsible.
How do I know whether I need a new air outlet or new tubing?
Inspect both components. If the tubing is cracked or damaged, tubing may be the problem. If the machine-side outlet is cracked, broken, or damaged, the outlet may require replacement.
Is the AirSense 11 the same as AirCurve 11?
No. AirSense 11 is a CPAP/APAP platform, while AirCurve 11 is a bilevel platform. Both are part of ResMed’s Air11 family, but they provide different types of therapy.
Can I use AirSense 10 accessories on AirSense 11?
Do not assume compatibility. ResMed distinguishes Air10 and Air11 accessories, so the exact machine and accessory should be verified before purchase.
Where can I buy ResMed CPAP replacement parts?
Replacement PAP components can be available through medical equipment suppliers and authorized sources. When shopping, verify the exact machine model and replacement-part compatibility.
A Simple Air Outlet Buying Checklist
Before placing your order, ask yourself:
Do I have an AirSense 11 or AirCurve 11?
Is the damaged component actually the machine’s air outlet?
Have I checked the part number?
Am I using heated or standard tubing?
Does the replacement listing clearly state Air11 compatibility?
Am I buying from a reputable medical equipment supplier?
If you can answer these questions, you are much more likely to select the correct component.
Why Patients Should Not Ignore Small Equipment Problems
Sleep therapy is often part of a nightly routine.
When everything works, you may barely think about the equipment.
But when a connection becomes loose or a component breaks, the problem can quickly become frustrating.
That is why regular inspection matters.
You do not need to become a CPAP technician. You simply need to recognize when something looks different from normal.
A cracked connector, damaged tubing, or loose machine connection deserves attention.
And if you are unsure, asking your DME supplier is often easier than guessing.
