ResMed Full Face Cushion for AirFit F40 Series CPAP Masks

ResMed's AirFit F40 Full Face AdaptiSeal Cushions are made of ultra soft silicone and feature an innovative, minimal contact design that sits below the nose -- covering just the mouth and the nostrils -- to reduce contact with the face and eliminate problematic touch-points like the nasal bridge and upper cheeks.

SIZES: AdaptiSeal Cushions come in three sizes -- Small Wide, Medium & Large. All AirFit F40 Masks use a single frame size so any AdaptiSeal Full Face cushion can be used with any F40 series mask frame. If you would like to change the size of your mask, you can just purchase a different cushion size and attach it to your existing F40 mask frame.
