Full Face Masks
The Smallest Full Face Mask That Doesn't Feel Like One – Ultra-Compact Comfort
ResMed's smallest tube-down full face mask. Delivers full face therapy performance with the lightweight feel and visual open freedom of an under-nose nasal mask.
Why the AirFit™ F40 is Different
If you've avoided full face masks because they feel bulky, claustrophobic, or leave sore spots on your nasal bridge, the AirFit™ F40 changes everything. By placing the soft cushion under your nose rather than over it, you get full nose-and-mouth sealing with minimal facial coverage.
