Introduction: ResMed AirFit F20 Cushion Medium
A comfortable CPAP mask can make a big difference in your nightly routine. When your mask starts leaking air, feels uncomfortable, or shows signs of wear, it may be time to replace the cushion. The good news is that you may not need to purchase an entirely new mask.
The resmed airfit f20 cushion medium is a replacement cushion designed for the ResMed AirFit F20 full-face CPAP mask. It covers both the nose and mouth and uses soft silicone with InfinitySeal™ technology to help maintain a reliable seal while you sleep.
At Alfa Healthcare Supply Inc., we understand that choosing the correct CPAP supplies can feel confusing, especially when several similar products are available. This guide explains the cushion’s features, compatibility, sizing, cleaning routine, replacement signs, and buying considerations in simple language.
What is the ResMed AirFit F20 Cushion Medium?
The resmed airfit f20 cushion medium is the medium-size silicone cushion used with the ResMed AirFit F20 full-face mask. It creates a seal around the nose and mouth, helping direct CPAP airflow into the airway during prescribed sleep apnea therapy.
Unlike purchasing a complete mask system, buying a replacement cushion allows you to keep your existing compatible mask frame, headgear, and elbow when those components remain in good condition.

The cushion is also compatible with the AirFit F20 for Her full-face mask. However, it is important to distinguish the AirFit F20 silicone cushion from other replacement cushions that may look similar but use different materials or have different care instructions.
Before ordering, check your existing mask model and the size printed on your current cushion. This simple step can help you avoid purchasing the wrong replacement.
Key Features of the ResMed AirFit F20 Cushion Medium
1. Soft Silicone Construction
The resmed airfit f20 cushion medium uses silicone designed to sit against the face during CPAP therapy. Its flexible construction helps the cushion adapt to facial contours while maintaining contact around the nose and mouth.
A cushion that fits correctly can help reduce unwanted air leaks and make nightly therapy more comfortable.
2. InfinitySeal Technology
ResMed’s InfinitySeal technology is designed to support a reliable seal across different facial shapes and positions. The cushion has varying thicknesses and a flexible design that allows some movement during sleep.
Although the technology helps support a good fit, no cushion can guarantee a leak-free experience for every person. Correct sizing, proper positioning, and suitable strap adjustment remain important.
3. Full-Face Coverage
This cushion belongs to a full-face mask system. It covers both the nose and mouth, making it an option for people whose prescribed CPAP setup requires full-face coverage.
Whether this mask style is right for you depends on your individual needs and the recommendations of your healthcare provider.
4. Easy Cushion Replacement
The resmed airfit f20 cushion medium can be removed from the compatible mask frame and replaced without automatically replacing the entire mask assembly.
This can be helpful when the frame and other components are still in good condition but the silicone cushion has become worn, damaged, or difficult to seal.
5. Multiple Size Options
The AirFit F20 cushion family is available in Small, Medium, and Large sizes. The medium version is intended for users whose measurements match the medium sizing guide.
A medium cushion is not automatically the right choice for every adult. Use the manufacturer’s sizing guide to determine the appropriate size for your face.
Benefits of Choosing the Correct Medium Cushion
Selecting the right replacement part can help make your CPAP routine easier to manage.
A more dependable seal: A properly fitted cushion helps limit air escaping around the mask edges.
Improved comfort: A cushion in the correct size can help reduce unnecessary pressure caused by poor positioning or excessive strap tightening.
Convenient maintenance: Replacing a worn cushion can be simpler than replacing an entire mask system when the other parts are still usable.
Support for regular therapy: Maintaining clean, functional equipment can help you follow your prescribed treatment routine more comfortably.
Less product confusion: Confirming the exact model and size before purchasing helps you choose a component intended for your existing mask.
Remember that the cushion is one part of the complete CPAP setup. Your mask frame, headgear, tubing, and machine must also be maintained according to their respective instructions.
Is the ResMed AirFit F20 Cushion Medium Compatible With Your Mask?
Compatibility is one of the most important things to confirm before purchasing.
The resmed airfit f20 cushion medium is designed for these compatible mask systems:
- ResMed AirFit F20 full-face mask.
- ResMed AirFit F20 for Her full-face mask.
The medium cushion is a replacement component, not a complete CPAP mask. It does not include all the parts needed to assemble a new mask system.
Do not assume that a cushion fits another mask simply because the product name contains F20. For example, the AirTouch F20 uses a memory-foam cushion rather than the standard silicone AirFit F20 cushion. Although some AirTouch and AirFit components have cross-compatibility, you should verify the exact component and current manufacturer instructions before ordering.
If you are uncertain about your mask model, check the product label, original packaging, or manufacturer’s documentation.
How to Replace the ResMed AirFit F20 Cushion Medium
Replacing the cushion is generally straightforward. Follow the instructions provided with your mask.
Step 1: Remove the Mask
Disconnect the mask from the CPAP tubing as directed in the user guide. Place the mask on a clean, flat surface.
Step 2: Remove the Old Cushion
Hold the mask frame securely and gently pull the old cushion away from it. Avoid bending or forcing the frame.
Step 3: Inspect the Frame
Check the frame for cracks, damage, or other signs of wear. A damaged frame may prevent the replacement cushion from fitting correctly.
Step 4: Attach the New Cushion
Align the replacement cushion with the frame opening and press the components together until the cushion is securely seated.
Step 5: Check the Assembly
Inspect the connection around the cushion to ensure it is attached evenly. Reconnect the mask according to the manufacturer’s instructions.
Step 6: Test the Fit
Place the mask on your face and adjust the headgear evenly. Start your CPAP machine and check for unwanted air leaks. Avoid overtightening the straps to compensate for a poorly fitted cushion.
If you cannot obtain a comfortable seal, review the fitting guide or contact your equipment supplier or healthcare professional for help.
How to Clean and Maintain Your Cushion
Regular cleaning helps remove facial oils, dirt, and residue that may affect the cushion’s seal.
For the standard silicone AirFit F20 cushion, follow these general care steps and the instructions in your user guide.
- Remove the cushion from the mask when required by the cleaning instructions.
- Wash it gently using warm, drinking-quality water and mild liquid detergent.
- Use a soft brush if needed to remove dirt, following the manufacturer’s guidance.
- Rinse thoroughly so that no detergent remains.
- Allow the cushion to air-dry away from direct sunlight.
Avoid harsh cleaning chemicals and unapproved cleaning devices, as they may damage the mask components. Do not confuse these instructions with those for the AirTouch F20 memory-foam cushion, which has different care requirements.
Inspect your cushion regularly for tears, cracks, discoloration, stiffness, or other visible deterioration. Replace damaged parts rather than continuing to use them.
When Should You Replace Your Cushion?
Over time, repeated use and cleaning can affect a silicone cushion’s condition. Signs that your resmed airfit f20 cushion medium may need replacement include:
- Visible cracks, tears, or other damage.
- A cushion that has become stiff or visibly worn.
- Persistent air leaks despite correct positioning and appropriate strap adjustment.
- A cushion that no longer sits comfortably against your face.
- Residue or deterioration that cannot be resolved through proper cleaning.
ResMed’s general replacement guidance indicates that full-face cushions may need replacement as often as monthly, depending on their condition. Actual replacement needs vary, so inspect your equipment and follow your supplier’s guidance and any applicable insurance replacement schedule.
You should not wait for a specific date if the cushion is visibly damaged. Likewise, if leaks continue after replacing it, check the mask size, frame, headgear, and fit rather than assuming the cushion is the only possible cause.
Common Fit Problems and How to Address Them
Air Leaking Near the Nose
Check whether the cushion is positioned correctly at the top of the nasal bridge. Re-seat the mask gently and adjust the upper straps evenly.
Air Leaking Around the Mouth
Inspect the lower part of the cushion and make sure the mask is positioned correctly. Adjust the lower straps gently without pulling them too tight.
Red Marks or Facial Pressure
Excessive strap tension or an unsuitable cushion size may contribute to discomfort. Recheck the fit and consult your equipment provider if pressure marks persist.
Cushion Does Not Fit the Frame
Confirm that you purchased the correct AirFit F20 cushion and that it is seated properly. Never force a component into place if it does not align as expected.
If discomfort, skin irritation, or persistent leakage continues, seek advice from your healthcare provider or qualified CPAP equipment professional.
