Which Cushion Fits the ResMed AirFit F20? Silicone vs AirTouch Memory Foam
Quick answer: The ResMed AirFit F20 uses one universal frame that takes three cushion sizes: Small, Medium and Large. You can use either the standard silicone (InfinitySeal) cushion or the AirTouch F20 memory foam cushion on the same frame. The AirFit F20 for Her uses its own Small and Medium cushions, and AirTouch cushions fit it too. If your F20 is the non-magnetic version, buy non-magnetic replacement parts, because its frame system isn’t interchangeable with the standard magnetic F20.
What fits the AirFit F20?
| Part | Fits AirFit F20 | Notes |
|---|---|---|
| AirFit F20 silicone cushion (S, M, L) | ✅ | All three sizes fit the same frame |
| AirTouch F20 memory foam cushion | ✅ | Swaps in place of the silicone cushion |
| AirFit F20 for Her cushion (S, M) | ✅ on the For Her frame | AirTouch F20 cushions fit the For Her mask too |
| AirFit F20 non-magnetic frame system | ❌ with magnetic F20 parts | Buy non-magnetic parts for a non-magnetic mask |
| AirFit F30 or F30i cushion | ❌ | Different masks with different cushions. See which cushions fit the F30 → |
Check before you order: the mask name is printed on the frame. The non-magnetic version is labelled separately on its packaging.
Silicone or AirTouch memory foam: which cushion should you choose?
The F20 frame lets you choose the cushion material. Some people keep one of each and switch depending on the night.
Silicone cushion (InfinitySeal)
- The cushion that comes standard with the AirFit F20
- Washable with warm water and mild soap
- Durable, with a familiar silicone feel
- A good default for most users
AirTouch F20 memory foam cushion
- UltraSoft foam that moulds gently to the face
- Many users find it softer, with less pressure on the skin
- Can be more forgiving around facial hair
- Not washable. Wipe it clean daily; never rinse or submerge it.
- Designed as a monthly disposable cushion
How to decide:
- Want the lowest upkeep and a washable cushion? Choose silicone.
- Get red marks or skin irritation, or want a softer feel? Try AirTouch.
- Not sure? Many users buy one AirTouch cushion to try alongside their silicone cushion. Both fit the same frame.
How to choose your F20 cushion size
- Already using an F20? Reorder the size you have now. It’s printed on the cushion.
- Air leaking at the top near your eyes, or the cushion sits too high? You may need a smaller size.
- The cushion presses on your nose bridge, or doesn’t cover your mouth fully? You may need a larger size.
- First time? ResMed provides a fitting template for the F20. A fit pack or your provider can help you choose.
The AirFit F20 for Her is a compact version designed for smaller faces, in Small and Medium.
About the magnetic clips
The standard AirFit F20 uses small magnets in the frame and lower headgear clips so the headgear snaps on and off easily. ResMed lists certain implants and medical devices that magnets may affect, and advises keeping the mask magnets at least 6 inches (150 mm) away from them. Check the mask’s user guide.
If magnets aren’t suitable for you, or for someone who sleeps close to you, ResMed makes a non-magnetic AirFit F20. Its frame system is separate from the standard F20, so buy replacement parts labelled non-magnetic. Your provider can advise which version suits you.
How to care for and replace your F20 cushion
Silicone cushion
- Wash daily or as directed with warm water and a mild soap, rinse well and air-dry
- Many users replace full-face cushions about once a month, in line with common resupply schedules
AirTouch memory foam cushion
- Wipe daily with a damp cloth or mask wipe; never wash or submerge it
- Replace about every 30 days
Replace sooner if you notice:
- New leaks, especially near the eyes
- Silicone that feels sticky, stiff or stretched, or foam that’s discoloured or has lost its shape
- Needing to tighten the headgear more than before
- More red marks in the morning

Replacement cushions don’t require a prescription. A complete F20 mask (frame, cushion and headgear together) does.
