ResMed AirTouch F40 – ComfiSoft Replacement Cushion

The ResMed AirTouch™ F40 Replacement Cushion features innovative ComfiSoft™ fabric-fused silicone technology, providing a soft, breathable surface against the skin while maintaining a comfortable and secure seal throughout the night.

Designed with an ultra-compact, under-the-nose profile, the cushion minimizes facial contact and reduces pressure on the nasal bridge. Its moisture-wicking fabric offers a comfortable alternative to traditional silicone cushions, making it an excellent option for users seeking a softer feel during CPAP therapy.

Compatible with both the ResMed AirTouch F40 and AirFit F40 full-face masks, this replacement cushion allows existing AirFit F40 users to experience ComfiSoft fabric comfort without purchasing an entirely new mask.

Key Features & Technology

ComfiSoft™ Fabric Cushion – Soft, Breathable Comfort

Combines soft, moisture-wicking fabric with flexible silicone to provide a gentle surface against the skin. The breathable material offers an alternative for users who experience discomfort or moisture buildup with traditional silicone cushions.

AdaptiSeal™ Technology – Flexible, Reliable Seal

Designed to adapt to individual facial contours and movement, helping maintain a secure seal without requiring excessive mask tightness.

Ultra-Compact Design – Minimal Facial Contact

The cushion sits comfortably beneath the nose while covering the mouth, eliminating contact with the nasal bridge. This low-profile design reduces facial coverage and allows an open field of vision.

AirFit F40 Compatibility – Easily Switch Cushion Types

The AirTouch F40 ComfiSoft cushion is interchangeable with the traditional silicone AirFit F40 cushion.

Both cushions fit the same F40 mask frame and use the same headgear, allowing users to switch between fabric and silicone without replacing their entire mask system.
