ResMed AirFit™ F40 Replacement Full Face Cushion
Maintain an optimal, comfortable CPAP seal every night with the official ResMed AirFit™ F40 Replacement Full Face Cushion. Specially designed for the minimal-contact AirFit F40 full face mask, this cushion features ResMed’s advanced AdaptiSeal™ soft silicone technology, which gently adapts to your unique facial contours to help maintain a strong, reliable seal through every sleep position.
Engineered to rest comfortably underneath the nose rather than over the nasal bridge, the F40 cushion eliminates pressure points, soreness, and red marks while providing the complete therapy coverage that mouth breathers and high-pressure users depend on. Regular replacement ensures peak hygiene, prevents air leaks, and prolongs the lifespan of your CPAP setup.
Who Is This Product For?

How to Clean & Maintain Your F40 Cushion

- Gently rub with a mild liquid detergent and warm, drinking-quality water.
- Avoid using stronger cleaning products or harsh chemicals as they may damage the silicone or leave harmful residue.
- Rinse again thoroughly under clean, warm running water.
- Place the cushion flat on top of a clean towel to air dry out of direct sunlight.
