ResMed AirFit F20 Full Face CPAP Mask

ResMed AirFit F20 Full Face CPAP Mask

The AirFit F20 is ResMed's full face mask for anyone who breathes through their mouth, deals with nasal congestion, or just can't hold a seal with a nasal mask overnight. It covers your nose and mouth with one InfinitySeal silicone cushion, so you're not fighting leaks every time you shift position or open your mouth. It's a solid pick if you're one of our mouth breathers looking for a mask built around that.

The frame sits under your eyes instead of across the bridge of your nose, so you keep a clear line of sight to read, watch TV, or wear glasses in bed. Magnetic clips on the lower headgear straps let you snap the mask on and pull it off in one motion, and the quick-release elbow disconnects from your hose without breaking your seal. It comes in Small, Medium, and Large, plus a For Her fit in Small and Medium with lavender accents, worth trying if the standard sizing runs big on you.

This is the silicone version of the F20. If you'd rather try a softer cushion, the AirTouch F20 uses the same frame and headgear with a memory foam cushion instead, so you can switch between the two whenever you want.

Like any CPAP mask, the AirFit F20 requires a prescription, and it's FSA/HSA eligible. Because the headgear uses magnetic clips, check the magnet safety FAQ below before you buy if you or anyone who sleeps near you has a pacemaker or another implanted medical device.
