About this cushion
The AirFit F40 cushion is the part of the mask that seals against the face, covering the nose and mouth. Over time, cushions wear and lose their seal, so a fresh cushion keeps your mask fitting and performing like new. This genuine ResMed cushion is made of soft silicone for a comfortable, secure seal, and comes in several sizes to match your fit. It's a compact full face cushion designed for a minimal, low-contact fit.
