The all-new ResMed AirFit F20 full face mask is part of the ResMed family of full-face style CPAP masks. This style of sleep apnea interface is designed to cover your nose and mouth, allowing you to breathe through either while sleeping. The F20 and F20 for Her are much lighter weight and more comfortable than full face masks of the past. If your current mask is leaking air around your eyes or is difficult to obtain a seal, then the AirFit and AirTouch series may be able to help with your CPAP compliance. The AirFit F20 is equipped with an innovative new cushion design, InfinitySeal Cushion Technology, and a variety of other design enhancements. The InfinitySeal cushion starts at the bridge of the nose and falls below the mouth to provide CPAP therapy to the nose and mouth. This new mask cushion features specially-designed infinity loops and varying thickness levels designed to reduce blowout and provide support at the sides of the nose. The frame is soft and flexible and includes integrated padding. The result is a ResMed mask that comfortably moves with you and provides a reliable seal throughout the night, regardless of sleep position. The AirFit F20 is the most technologically advanced full face mask ever. With this simple design, each size cushion can easily be clicked into the standard AirFit F20 frame.The AirFit F20 Full Face Mask is similar to the AirFit F10 Full Face CPAP Mask with Headgear. To increase the comfort of the mask, ResMed added padding to the mask frame and headgear, making the ResMed AirFit softer and more comfortable.
