Introduction: AirFit F40 Cushion Medium
A comfortable CPAP mask can make a big difference in your nightly sleep routine. If your mask feels uncomfortable, develops air leaks, or leaves marks on your face, it may be time to check the cushion. The AirFit F40 cushion medium is a replacement part designed for people who use the ResMed AirFit F40 full face CPAP mask.
The AirFit F40 is designed with a soft, under-the-nose cushion that helps provide a secure fit without covering the bridge of the nose. Its flexible design supports comfortable movement during sleep. For people who want to maintain their existing mask without purchasing a completely new system, replacing the cushion can be a practical option.
At Alfa Healthcare Supply Inc., we understand that finding the right medical supplies should be simple and convenient. This guide explains the features, sizing, cleaning, replacement, and buying considerations for the AirFit F40 cushion medium so you can make an informed decision.
What is the AirFit F40 Cushion Medium?
The AirFit F40 cushion medium is a replacement silicone cushion for the ResMed AirFit F40 full face CPAP mask. It creates the contact surface between the mask and your face, helping maintain a comfortable seal while your CPAP machine delivers prescribed air pressure.
The cushion uses ResMed’s AdaptiSeal design, which is intended to adapt to facial contours and support a reliable seal. The mask rests beneath the nose rather than across the nasal bridge, offering an alternative to traditional full face mask designs.
The AirFit F40 cushion medium is intended for users whose facial measurements match the medium size according to the manufacturer’s sizing guide.
Important: This product is a cushion replacement, not a complete CPAP mask. Check the product listing carefully to confirm what is included before ordering.
Key Features of the AirFit F40 Cushion Medium
1. Soft Silicone Construction
The cushion uses flexible silicone designed to sit comfortably against the face. Its soft construction helps create a seal around the nose and mouth during CPAP therapy.
Regular cleaning and proper positioning can help maintain comfort and performance over time.
2. Under-the-Nose Design
The AirFit F40 uses an under-the-nose cushion rather than a traditional design that rests over the bridge of the nose. Some users may find this style more comfortable, particularly if they experience pressure marks around the upper nose with other mask designs.
Individual comfort varies, so correct sizing remains important.
3. Designed for a Secure Seal
A properly fitted cushion helps reduce unwanted air leaks around the mask. The AirFit F40 cushion medium is designed to work with the compatible AirFit F40 mask frame.
If air escapes around your nose or mouth, reposition the cushion and check the headgear adjustment before assuming that you need a different size.
4. Replacement Without Buying a Whole Mask
When the cushion becomes worn but the other mask components remain in good condition, replacing the cushion may be more economical than replacing the entire mask system.
The AirFit F40 cushion medium allows eligible users to replace this specific component while continuing to use their compatible mask frame and headgear.
5. Supports Everyday CPAP Use
CPAP users need equipment that fits comfortably into their daily routines. Cleaning the cushion regularly, checking for damage, and replacing it when needed can help keep the mask in suitable working condition.
Who Should Choose the Medium Size?
Choosing the correct size is essential for comfort and effective mask sealing. The AirFit F40 cushion medium may be appropriate for users whose nose measurements fall within the medium sizing area shown in ResMed’s official fitting template.
However, medium is not automatically the best choice for every adult.
Consider these sizing tips:
- Check your measurements: Use the official AirFit F40 fitting template rather than relying only on your usual mask size.
- Review your current mask: If your existing AirFit F40 cushion is medium and fits comfortably, this can be a useful reference when ordering a replacement.
- Look for gaps: A cushion that is too large or too small may not seal properly.
- Avoid excessive strap tightening: Tightening the headgear too much may create discomfort without correcting a sizing problem.
- Follow the manufacturer’s instructions: Use the recommended fitting procedure to position the cushion correctly.
ResMed offers the AirFit F40 cushion in Small-Wide, Medium, and Large sizes. These options help users select a cushion based on their facial measurements.
How to Fit the AirFit F40 Cushion Medium
Proper positioning helps the cushion create a comfortable seal. Follow the manufacturer’s instructions for your specific mask model.
Step 1: Inspect the Cushion
Before use, check the cushion for tears, cracks, unusual deformation, or other visible damage. Do not use a damaged component.
Step 2: Position the Cushion
Place the cushion beneath your nose as directed in the fitting guide. Make sure it sits evenly against your face without folds or pinched areas.
Step 3: Position the Headgear
Place the headgear over your head with the straps positioned correctly. Attach the magnetic clips as instructed in the user guide.
Step 4: Adjust the Straps
Make small, even adjustments to the upper and lower straps. The mask should feel secure without creating unnecessary pressure.
Step 5: Check the Seal
Turn on your CPAP machine and check for leaks while air is flowing. If air escapes around the nose, gently reposition the cushion and readjust the straps as needed.
If the mask continues to leak despite correct positioning, review the sizing instructions or contact your healthcare provider or equipment supplier for help.
How to Clean the AirFit F40 Cushion Medium
Daily cleaning helps remove facial oils, dirt, and residue that can affect the cushion’s condition and fit.
Follow these general care steps based on ResMed’s guidance:
- Disconnect the mask from the CPAP equipment as instructed.
- Remove the cushion according to the AirFit F40 disassembly instructions.
- Wash it in warm, drinking-quality water using a mild liquid detergent.
- Gently clean the surface without using abrasive brushes or harsh chemicals.
- Rinse thoroughly to remove all detergent.
- Place the cushion on a clean towel and allow it to air-dry away from direct sunlight.
- Reassemble the mask according to the manufacturer’s instructions.
Avoid strong cleaning products, oils, and direct heat unless the manufacturer specifically permits them. Always check the user guide for complete cleaning and maintenance instructions.
When Should You Replace the Cushion?
Over time, daily use can affect the cushion’s flexibility, surface condition, and ability to maintain a good seal.
ResMed’s replacement guidance recommends replacing the AirFit F40 cushion approximately once a month. Actual replacement needs can vary with use, condition, and applicable insurance or supplier policies.
Consider checking your cushion for these signs:
- Persistent air leaks despite correct fitting.
- Visible tears, cracks, or other damage.
- A cushion that no longer maintains its shape.
- Persistent residue or deterioration that remains after proper cleaning.
- Discomfort that continues even after correct repositioning.
The AirFit F40 cushion medium should be replaced when necessary to maintain appropriate equipment condition. Do not wait for the cushion to fail completely if it shows clear signs of deterioration.
Common Problems and Practical Solutions
Air Leaking Around the Nose
Remove any folds in the cushion by gently repositioning it. Check that the headgear is not twisted and that the straps are adjusted evenly.
If leaks continue, verify the cushion size and follow the manufacturer’s troubleshooting guidance.
Red Marks or Facial Discomfort
Excessive strap tension, incorrect positioning, or an unsuitable size may contribute to discomfort. Loosen and readjust the headgear according to the fitting guide.
If skin irritation persists, stop using the equipment if necessary and consult your healthcare professional for advice.
Cushion Feels Loose
Check that the cushion is securely attached to the frame and that the correct replacement component was purchased. Inspect the attachment points for damage.
Cushion Looks Worn
A cushion that has lost its shape or developed cracks should be replaced. Cleaning cannot restore damaged silicone.
AirFit F40 Cushion Medium vs. Other Sizes
Selecting a cushion should be based on fit, not simply on the assumption that a larger or smaller size will feel better.
| Cushion size | General guidance |
| Small-Wide | For users whose measurements match the Small-Wide template |
| Medium | For users whose measurements match the Medium template |
| Large | For users whose measurements match the Large template |
The AirFit F40 cushion medium is one of three available cushion sizes. The manufacturer’s fitting template is the best starting point for selecting the appropriate option.
Remember that cushion size and headgear size are separate considerations. A medium cushion does not necessarily mean you need medium headgear.
What to Check Before Buying
Before ordering a replacement, confirm the following details:
- Mask compatibility: The cushion must be specifically designed for the ResMed AirFit F40.
- Correct size: Verify that medium matches your fitting measurements.
- Product contents: Confirm that the listing includes the cushion only if that is what you need.
- Condition: Buy a new, appropriate replacement from a reliable medical supply source.
- Replacement schedule: Check the cushion’s condition and follow the manufacturer’s recommended replacement guidance.
- Return policy: Review the supplier’s policy for medical accessories before purchase.
The manufacturer’s US product guide lists part number 64628 for the AirFit F40 Cushion Medium. Confirm the part number against the current product listing and your mask model before ordering.
