ResMed AirMini is one of the smallest portable CPAP on the market today. Portable and versatile, AirMini includes multiple proven therapy modes and features like waterless humidification* designed to provide a quality therapy experience wherever you sleep. AirMini includes three therapy modes: CPAP, AutoSet (APAP) and AutoSet for Her (fAPAP). Whether you're traveling or napping at home, ResMed AirMini makes it simple to get CPAP therapy anywhere. Effective waterless humidification when used with AirFit P10 for AirMini, AirFit N30 for AirMini, AirFit N20 and AirTouch N20 as well as HumidX F20 for AirFit F20 and AirTouch F20. Compatible nasal and nasal pillows masks also work with HumidX Plus, which is optimized for dry and high-altitude environments where humidity levels are low. Note: The tubing on the AirMini is a smaller size than the tubing on a regular CPAP device, and you will need the HumidX adapter and AirMini tubing to connect to your existing mask. The ResMed AirFit F30 mask is the ONLY ResMed mask that DOES NOT come with a HumidX option. All other ResMed masks will come with HumidX cartridges. *Not available when using full face masks
