ResMed AirTouch F30i Cushion (ComfiSoft™ with AdaptiSeal™)

Quick answer: This is the genuine ResMed replacement ComfiSoft™ cushion with AdaptiSeal™ for the AirTouch F30i full face mask (both the Clear and Comfort versions). It’s a dual-layer seal — a breathable, moisture-wicking silicone-coated fabric over a flexible AdaptiSeal silicone core — that sits under the nose and over the mouth, feeling soft and cool against the skin instead of plain silicone. The cushion is the part that seals and wears fastest, so replacing it on schedule keeps a clean seal. Available in Small-Wide, Medium, and Large. Frame and headgear not included.

What’s included

• 1 × AirTouch F30i ComfiSoft cushion with AdaptiSeal (in your selected size)

Frame and headgear not included.

About this part

The cushion does the actual sealing work, and it’s a consumable by design. The AirTouch F30i’s ComfiSoft™ cushion with AdaptiSeal™ is what defines the mask — a two-layer design:

• ComfiSoft™ outer layer — a breathable, moisture-wicking silicone-coated fabric that’s soft and cool against the skin, gentle on sensitive skin, and helps reduce red marks and irritation compared with plain silicone.
• AdaptiSeal™ silicone core — a flexible inner seal that adapts to the face and flexes as you move, holding a stable seal without rigid plastic at the seal point.

It’s an UltraCompact full face cushion — it seals below the nostrils and over the mouth (not across the nasal bridge), so there’s no bridge pressure and a clear field of view. As a full face cushion, it suits mouth breathers and people with nasal congestion.

This one cushion fits both AirTouch F30i versions — the Clear (transparent frame) and the Comfort (fabric-wrapped frame) share the same ComfiSoft/AdaptiSeal cushion.

AirTouch (ComfiSoft) vs AirFit (silicone): this fabric-over-silicone cushion is for the AirTouch F30i. The AirFit F30i uses a plain silicone cushion instead — a different part.

Important: don’t cross-use cushions between F30i and X30i

The F30i and X30i masks share a frame, and cushions may physically click across them — but ResMed has not clinically validated cross-using cushions between the F30i and X30i (each has its own venting and CO₂-washout design). Use this cushion only with the AirTouch F30i.

Care & replacement

Because it’s a fabric-and-foam-style cushion, care for it per ResMed’s AirTouch guidance — fabric/foam cushions are not cleaned like silicone (don’t submerge/scrub). Keep it dry, away from direct sunlight. Fabric cushions are typically replaced a little more often than silicone — replace it when it loses softness, looks soiled or discoloured, or no longer seals well.
