The cushion is the part of your mask that touches your face every night, so it is the part worth keeping fresh. This is the ComfiSoft replacement cushion for the AirTouch F40, the same fabric-and-silicone blend that makes the mask feel gentle under your nose.
It is interchangeable with the AirFit F40 cushion, so it fits into the F40 family whether you started with fabric or silicone. Each cushion comes with its own QuietAir vent, which means a replacement renews your venting too.
Choose Small-Wide, Medium, or Large to match the size you wear now. It is also the part on the shortest replacement schedule, which you will find below.
