Enjoy a comfortable and secure fit with the AirFit F40 Full Face AdaptiSeal Cushions. These replacement cushions are designed for use with all AirFit F40 CPAP & BiLevel Masks. They are made of ultra-soft silicone that adapts to your face, covering just the mouth and nostrils. This design reduces contact with your face and eliminates problematic touch-points like the nasal bridge and upper cheeks.

The AdaptiSeal Cushions are available in three sizes—Small Wide, Medium, and Large. Since all AirFit F40 Masks use a single frame size, you can easily switch cushion sizes if needed. Simply purchase a different cushion size and attach it to your existing F40 mask frame for a personalized fit.
