Replacement Cushion for AirFit F20:
If your sleep is disturbed by the CPAP mask, you can find something comfortable that works for you. For people with ResMed AirFit F20 full face mask, one of the crucial components to keep up is the cushion. It can be impacted by the use over time, facial oils and regular cleaning. A worn cushion may make for a less comfortable journey and a less reliable mask fit, so try changing the cushion.
We at Alfa Healthcare Supply Inc. know finding the right CPAP supplies shouldn’t be difficult. In this guide, you will learn how to pick a replacement cushion for AirFit F20, understand the proper size, know when to replace and how to take care of your AirFit F20 cushion.
This information can help you make an informed decision if you are ordering replacement equipment for the first time, or maintaining your existing CPAP equipment.
What is a Replacement Cushion for AirFit F20?
The removable silicone part against your face that forms a seal around your nose and mouth is called a replacement cushion for AirFit F20. It is designed to fit the ResMed AirFit F20 full face CPAP mask.
The cushion snugly fits into the mask frame and headgear to ensure the mask stays in place when sleeping. A good fit minimizes air leakage and ensures proper CPAP flow delivery.
The AirFit F20 features InfinitySeal™ cushion technology, ResMed says. It’s designed to fit various facial shapes and offer slight flexibility when sleeping.

It’s not necessary to replace a mask if the cushion wears out. If the frame and other parts are still in good shape, it might just be feasible to change the cushion.
Important: Choose a cushion made for the AirFit F20 or another model specifically confirmed as compatible. A cushion intended for a different mask may not fit correctly.
Key Features of the AirFit F20 Replacement Cushion
Before purchasing a replacement cushion for AirFit F20, it helps to understand the features that make this component important.
1. InfinitySeal Cushion Technology
Infinitiesseal technology is adopted by AirFit F20 silicone cushion. It is carefully designed in shape and with different material thicknesses to provide a seal over various contours of the face.
Use of a good seal can minimize air leakage around the edges of the mask. The outcome will however be dependent on choosing the right size, ensuring the mask fits correctly and the headpiece is adjusted correctly.
2. Soft Silicone Construction
Silicone cushion is in direct contact with the skin. By keeping it clean and in good working order, you can ensure that you’re comfortable while using it regularly for CPAP therapy.
When the silicone gets stiff, damaged, sticky, and/or visibly worn, it may no longer offer the fit you need.
3. Three Available Sizes
The replacement cushion for AirFit F20 is available in three sizes:
- Small: May suit users who need a smaller cushion profile.
- Medium: Designed for users who fit the medium sizing guide.
- Large: May be appropriate for users who need a larger cushion profile.
Do not select a size based only on your usual clothing size or assumptions about your face shape. Use the ResMed mask sizing guide and check the size printed on your current cushion.
4. Interchangeable Cushion Design
The AirFit F20 cushion should fit onto the AirFit F20 mask frame. This helps users to change the cushion without changing the entire mask assembly.
AirFit F20 and AirFit F20 for Her have compatible replacement cushion designs but the right size remains crucial.
How to Choose the Right Replacement Cushion for AirFit F20
Choosing the correct cushion is an important step toward maintaining a comfortable CPAP experience.
Step 1: Check Your Existing Mask
Check the mask you are using and make sure it is a ResMed AirFit F20. If you have any doubt, look at the product label, package or user guide.
There is a relation between the AirFit F20 and AirTouch F20 mask systems, but different materials are used in the cushions. Double check cushion type prior to purchase.
Step 2: Identify Your Current Size
Look at the bottom of your current cushion for the marking. It could indicate a small, medium or large (S, M or L).
If the existing cushion is fitting and is not leading to consistent leakage or discomfort, it might be a prudent initial approach to continue using the same size cushion.
Step 3: Review the Sizing Guide
If you’re having frequent leaks or an existing cushion is not comfortable for you, please refer to the official ResMed sizing guide.
Align the guide as directed with the bridge of your nose and area below your lower lip. Do not just guess, but follow the advice of the guide.
Step 4: Consider Comfort and Skin Contact
You should be able to fit your cushion nicely over your face without having to put in a lot of headgear pressure.
If there are pressure marks you can’t remove, the mask is uncomfortable or it leaks even with careful use, reexamine the fit and talk to your sleep-care provider as needed.
Step 5: Confirm Compatibility Before Ordering
Check for model, size and material before buying a new cushion for AirFit F20. This quick test can help ensure that you are not ordering an incompatible part.
When Should You Replace Your AirFit F20 Cushion?
CPAP mask cushions experience regular wear because they contact your skin every night. Natural facial oils, moisture, repeated cleaning, and movement during sleep can gradually affect the silicone.
ResMed’s replacement guidance indicates that full face cushions may need replacement as often as monthly, depending on their condition and the applicable supply schedule.
Consider replacing your cushion when you notice:
- Frequent air leaks: Air escapes around the cushion even after you check the fit and headgear.
- Visible damage: The silicone has tears, cracks, or other signs of deterioration.
- Changes in flexibility: The cushion no longer feels or behaves as it did when new.
- Persistent discomfort: The cushion causes rubbing or irritation despite correct positioning.
- Difficulty maintaining a seal: You need to tighten the headgear more than usual to control leaks.
- Cleaning problems: The cushion remains dirty or develops a surface condition that cannot be resolved with proper cleaning.
These signs do not all mean the cushion must be replaced immediately, but they warrant inspection. Follow the manufacturer’s care instructions and your equipment supplier’s replacement guidance.
Replacing a worn replacement cushion for AirFit F20 on an appropriate schedule may help you avoid unnecessary interruptions to your regular CPAP routine.
How to Clean and Maintain Your AirFit F20 Cushion
Good maintenance helps keep your CPAP mask clean and allows you to identify wear early.
Daily Cleaning
Follow the manufacturer’s instructions for routine cleaning.
- Remove the cushion from the mask frame as directed in the user guide.
- Wash the silicone cushion gently using warm, drinking-quality water and mild liquid detergent.
- Avoid harsh cleaners, strong chemicals, and products that may damage the material.
- Rinse thoroughly to remove soap residue.
- Place the cushion on a clean towel and allow it to air-dry away from direct sunlight.
Always check the instructions supplied with your specific mask. Avoid abrasive brushes or cleaning methods that could damage the cushion.
Inspect the Cushion Regularly
After cleaning, look for cracks, tears, discoloration, or other changes. Check the sealing edge carefully because damage in this area can affect how the cushion sits against your face.
If the cushion is damaged or no longer seals properly, replace it rather than relying on increasingly tight headgear adjustments.
Store It Properly
Keep your cushion in a clean, dry location away from direct sunlight, excessive heat, and contaminants. Proper storage can help protect the material between uses.
How to Install a Replacement Cushion for AirFit F20
Replacing the cushion is generally straightforward when you follow the correct instructions.
Before starting: Disconnect the mask from your CPAP tubing and follow the manufacturer’s instructions for disassembly.
- Remove the old cushion. Gently pull it away from the mask frame.
- Inspect the frame. Check for visible damage, residue, or other issues that might affect the new cushion.
- Align the replacement. Position the new cushion so its openings align correctly with the frame.
- Attach the cushion. Press the components together until the cushion is securely seated.
- Check the fit. Put on the mask and position it according to the AirFit F20 fitting guide.
- Adjust the headgear. Make small, even adjustments without overtightening the straps.
- Check for leaks. Start your prescribed CPAP therapy and check the mask fit according to your device’s instructions.
If air continues to leak, reposition the cushion and review your sizing. Persistent leaks may indicate that you need a different size or professional fitting advice.
AirFit F20 Silicone Cushion vs. AirTouch F20 Memory Foam Cushion
Some CPAP users wonder whether they can change from the silicone AirFit F20 cushion to the memory foam AirTouch F20 cushion.
The two cushions differ in material and maintenance requirements.
| Feature | AirFit F20 | AirTouch F20 |
| Cushion material | Silicone | UltraSoft memory foam |
| Main characteristic | Flexible silicone seal | Soft foam facial contact |
| Routine cleaning | Wash as instructed | Follow foam-specific care instructions |
| Replacement | Based on condition and guidance | Based on condition and guidance |
| Compatibility | AirFit F20 frame | Compatible with the F20 platform, subject to model guidance |
ResMed confirms that the AirFit F20 and AirTouch F20 share the same general mask platform, with the cushion being a key difference. However, their care requirements are not interchangeable.
The AirTouch F20 memory foam cushion must not be cleaned by soaking or washing it like a standard silicone cushion. Follow the specific manufacturer’s instructions for that material.
If you prefer a washable silicone cushion, the replacement cushion for AirFit F20 may be the more suitable choice for your existing setup.

Common Problems and Practical Solutions
Why Does My AirFit F20 Cushion Leak?
Leaks may be caused by improper positioning, wrong size, unequal headgear and worn cushions. Adjust the mask and then make small adjustments. If it persists, check your sizing or consult a professional for advice.
Can I Replace Only the Cushion?
Yes. However, the frame and other parts of the mask are usually compatible and you can just replace the cushion – not the entire mask – if it is in good shape.
Does a New Cushion Guarantee Better Sleep?
Not necessarily. If the cushion was previously used, a new one may enhance fit, but a number of factors—such as proper CPAP settings, mask fit, comfort, and adherence—are important for sleep quality.
Can I Use a Medium Cushion If I Previously Used Large?
Maybe, but don’t alter the size without taking the fit into account. Refer to the manufacturer’s sizing guide and call for assistance when the existing size is not comfortable or it still leaks.
How Often Should I Clean the Cushion?
Silicone AirFit F20 cushion is recommended to be cleaned daily by ResMed. For full cleaning procedure, read the current user guide.
