AirFit/AirTouch F20 HumidX for ResMed AirMini Designed specifically for the AirFit and AirTouch F20 Full Face masks, the AirMini HumidX is a waterless humidification system that retains moisture and humidifies the air you breathe. The small heat and moisture exchangers (HME) provide comfortable and effective humidification to your sleep therapy with the ResMed AirMini travel machine. How HumidX works: Upon exhalation, heat and moisture is captured and stored within the HME's tiny paper ridges.
