ResMed AirTouch F40 Cushion

Restore that first-night seal

Cushions are consumables — skin oils and nightly wear slowly stiffen the seal until leaks creep in. The ResMed AirTouch F40 Cushion is the genuine factory replacement: breathable ComfiSoft™ fabric fused with an AdaptiSeal™ silicone membrane that re-adapts to your facial contours, with no pressure points at the nose or nasal bridge. QuietAir™ vent is integrated.

• ComfiSoft™ fabric construction: softer against the skin than all-silicone
• UltraCompact under-the-nose profile: less coverage, fewer red marks
• QuietAir™ vent built in: quiet nights, no extra parts to align
• Tool-free swap: press off, snap on — under a minute
• Size marked on shell: SW, M, or L molded into the plastic

Compatibility & replacement

Fits any F40 frame — AirTouch or AirFit. Available in Small-Wide, Medium, and Large. Replace every 1–3 months; follow the fabric-specific cleaning steps in the AirTouch F40 user guide (don't soak or machine-wash).

ComfiSoft™ Fabric Construction Breathable fabric fused with flexible AdaptiSeal™ silicone gives this cushion its signature soft feel — noticeably gentler against the skin than all-silicone, and it adapts to your facial contours without pressing on the nasal bridge.

UltraCompact Under-the-Nose Profile The cushion sits unobtrusively under the nose, covering a fraction of the face of a traditional full face cushion. Less contact means fewer red marks, less irritation, and less claustrophobia.

Integrated QuietAir™ Vent The diffused vent is built into the cushion itself, quietly dispersing exhaled air as you breathe — no separate parts to lose or misalign when you swap cushions.
