The AirTouch™ F20 is ResMed's softest mask ever and the first to use UltraSoft™ memory foam for a flawless blend of comfort and performance. The memory foam cushion also adapts to the unique contours of every face to help provide a secure seal across a wide range of therapy pressures. With the AirTouch™ F20, maintenance is fast and beyond simple. No soap, no water – a quick wipe down with non-alcoholic wipes keeps the memory foam clean. That’s it. And with regular cushion replacement every 30 days, patients experience a fresh feeling every time, like a clean set of sheets or a brand new shaving razor.
