For patients needing greater moisture support, ResMed HumidX Plus (6 Pack) delivers enhanced waterless humidification within the AirMini system. Designed for use in cooler or drier conditions—or for those experiencing significant dryness—it provides a higher level of moisture exchange compared to standard HumidX, improving comfort without the need for water chambers. Each unit is typically replaced every 30 days to maintain optimal performance and therapy comfort.
