Flexible Intuitive Frame with Open Field of View AirTouch F20's frame moves naturally to adapt to each individual facial contours. This results in minimizing facial contact points, improved stability, and a completely unobstructed view. As a result, you are free to read or watch TV while wearing your CPAP or BIPAP machine in comfort. Airtouch Memory Foam Technology The patented ResMed AirTouch F20's UltraSoft Cushion is ResMed's softest insert ever. The UltraSoft cushion is incredibly lightweight, comprised of breathable memory foam that provides considerable comfort; all from a breathable seal, even at higher pressure settings. These UltraSoft foam cushions are much more intuitive in their formation to facial features than most traditional silicone cushion cushions. Their breathability keeps them cool as well, so there is less 'mask sweat'. Cushions are available in three sizes: Small, Medium and Large. Since the memory foam inserts cannot be cleaned, it is strongly recommended that these foam inserts are replaced every 30-days. After this time, they start to lose integrity, which can comprise the seal. Plush Comfortable Fabric headgear & Quick-Release Magnetic Clips Plush padded Headgear, designed for considerable softness and stability. This plush headgear is included with all F20 full face masks. ResMed's patented rolled-edge fabric straps were created to allow the mask to be worn loosely. Coupled with the UltraSoft cushion, this combo allows this mask system to adapt to your individual facial contours, reducing pressure points. ResMed's lower strap magnetic clips help guide the headgear to its frame. This feature allows you to place and remove the headgear in an instant. Whisper Quiet 'QuietAir' Diffuser Elbow The ResMed AirTouch F20 Full Face Mask features ResMed's QuietAir Elbow. This patented mask elbow provides an almost silent, gentle air diffusion. Cleverly placed exhaust ports direct the air away from the mask user, and their sleep partner. This means a better night's sleep for everyone. Disconnecting is a breeze as well with the F20's elbow as it features patented quick-release squeeze-tabs. These tabs allow for an easy single-hand quick detachment. The QuietAir elbow also rotates 360° that attaches to its own independent tube swivel. Perfectly Compatible AirTouch F20 & AirFit F20 Provide Many Versatile Options The ResMed AirTouch F20 & AirFit F20 masks are created based on the same padded, flexible frame and plush headgear system. This means that all of the cushions and parts for both masks are completely interchangeable. The ResMed F20 family of AirTouch F20 & AirFit F20 products allow you free rein to customize your mask to suit your needs.
