ComfortFull Full Face Mask Has been designed to ensure the comfortable fit and effective therapy patients need to maintain compliance. Its cushion sits lower on the nose, eliminating pressure on the nose bridge. The StabilitySelector tilts the mask to allow for an optimal seal and comfort-without over tightening the headgear. The quick-release hose swivel and ball-and-socket headgear clips provide increased nighttime mobility and extended ease-of-use. Combined with a soft dual-flap cushion and the ComfortHeadgear , these features make ComfortFull the best option for a full-face mask.
