The ResMed AirFit F20 cushion from CPAP Supplies Canada is a genuine replacement full face cushion that renews the seal on your AirFit F20 or AirTouch F20 mask. It uses ResMed’s InfinitySeal silicone, a thin, flexible edge that holds a seal across a wide range of pressures and adjusts as you shift position through the night.

Why choose the ResMed AirFit F20 cushion?

• Genuine ResMed part. Built to the same spec as the cushion your mask shipped with, so the fit and feel stay consistent.
• InfinitySeal design. The tapered silicone flexes with your pressure setting to reduce leaks and red marks.
• Three sizes. Small, Medium and Large are marked on the base of each cushion so swaps are easy.
• Full face coverage. Seals over both the nose and mouth for mouth breathers and higher pressures.

Compatibility and sizing

This cushion fits the AirFit F20, AirFit F20 for Her, AirTouch F20 and AirTouch F20 for Her frames, and any size clicks onto any of those frames. If your current cushion still seals well, order the same size printed on its base. If you are new to the F20 line, ResMed’s fitting template can help you choose between S, M and L.

Frequently asked questions

How often should I replace it?
ResMed recommends replacing the cushion about once a month, or sooner if the silicone starts to feel sticky, stiff or no longer holds a seal.

Which frames does it fit?
It works with all AirFit F20 and AirTouch F20 series frames, including the for Her versions, so you keep your existing headgear and frame.
