The ResMed AirFit F40 Full Face Cushion is the genuine replacement AdaptiSeal cushion designed exclusively for the ResMed AirFit F40 Full Face CPAP Mask. Made from soft silicone, the AdaptiSeal cushion adapts to your unique facial contours, helping maintain a comfortable and secure seal throughout the night, even as you change sleeping positions.
The under-the-nose design covers the mouth area without extending over the nasal bridge, reducing facial contact, pressure marks, and feelings of claustrophobia compared to traditional full face masks. The cushion keeps your field of view open so you can comfortably wear glasses, read, or watch TV before bed while using therapy.
Each replacement cushion includes a new QuietAir vent ring, which diffuses exhaled air for quiet, less disruptive therapy. The cushion snaps onto the AirFit F40 frame for a quick, tool-free replacement. Available in three sizes, Small Wide, Medium, and Large, to match your current F40 setup. ResMed recommends replacing the cushion approximately every three months to maintain consistent seal performance and therapy comfort.
