The ResMed AirTouch F20 is a full-face mask built around a memory foam cushion, not silicone — it moulds to your face for comfort, but wears differently to a standard F20, so its care is genuinely different.

Memory foam cushion: unlike the standard AirFit F20's silicone cushion, this one is not washable — wipe it, don't soak it, and expect to replace it roughly every 2–4 weeks with regular use, faster than a silicone cushion. This is the single most common support question on this mask.

Headgear and magnetic clips: shared in style with the standard F20 — same quick-release magnetic clips, same roughly 6-month headgear life.

Frame: replaced less often; check for a cracked seal edge if leaks persist after a fresh cushion.

If you'd prefer a cushion you can wash and reuse for longer, the standard AirFit F20 silicone cushion fits the same AirTouch F20 frame and headgear — worth asking us before committing to another foam multi-pack.
