A worn cushion doesn’t always mean you need a complete new mask. The ResMed AirFit F20 replacement cushion replaces the silicone seal that sits around your nose and mouth, letting you keep your compatible F20 frame and headgear.
Choose this cushion when you want the AirFit F20’s washable silicone design. Available in Small, Medium and Large, it uses InfinitySeal technology to support the mask seal during therapy.
Before ordering: Check your mask model and cushion size. This listing is for the replacement cushion only.
Replace the part that needs attention: Keep serviceable mask components rather than buying a complete system.
Stay with a familiar material: A practical choice if silicone already works comfortably for you.
Make reordering simpler: Confirm your current cushion size before selecting your replacement.
Maintain your cleaning routine: The silicone cushion can be washed after each use.
This replacement is for people using a compatible AirFit F20 or AirFit F20 for Her full-face mask. The F20 platform also allows AirFit silicone and AirTouch memory-foam cushions to be interchanged.
It is particularly useful if your existing cushion is damaged or deteriorating while your other mask components remain in good condition.
If your mask has never fitted comfortably, seek sizing help before simply reordering the same cushion.
1. Mask model: Confirm that your mask belongs to the compatible F20 family. “Full-face mask” alone does not establish compatibility.
2. Cushion material: This is the AirFit F20 silicone cushion. It is different from the AirTouch F20 memory-foam cushion.
3. Cushion size: Choose Small, Medium or Large. If your current fit works well, check its size marking. If you are unsure, use the F20 sizing guide or ask for assistance.
One ResMed AirFit F20 replacement cushion in your selected size.
Frame, headgear, elbow and complete mask system are not included.
Need the whole setup? Explore the ResMed AirFit F20 complete mask system.
Remove the mask and gently pull the old cushion away from the frame.
Align the replacement cushion’s circular opening with the frame opening.
Push them together until the cushion is securely retained.
Refit your mask and check the seal before sleeping.
Follow the mask user guide for complete assembly and fitting instructions.
Clean after each use with warm, drinking-quality water and mild liquid detergent. Rinse thoroughly and allow it to dry away from direct sunlight.
These instructions apply to the AirFit F20 silicone cushion. Do not use the same washing routine for an AirTouch F20 memory-foam cushion.
Check whether the cushion is clean, correctly seated and properly fitted. Inspect it for visible deterioration.
A new cushion may help when the old seal is worn, but leaks can also involve fit or other mask components. If leaks continue, get help checking the complete setup rather than repeatedly tightening the headgear.
