The AirFit F20 headgear’s minimalistic and padded design helps provide a higher quality of comfort throughout your night. To make it easier to put on and take off, the ResMed F20 headgear features two lower straps that connect with magnetic headgear clips to the base of the AirFit F20 mask frame. This replacement headgear is only compatible with the AirFit™ F20 Full Face Mask and the AirFit™ F20 For Her Full Face Mask.
