HumidX™ waterless humidification*
Humidification, but not as you know it
HumidX and HumidX Plus take portable humidification to whole new level.** Exclusive to AirMini, HumidX and HumidX Plus are small heat and moisture exchangers (HME) that are designed to provide comfortable and effective*** humidification.
HumidX
ResMed’s standard waterless humidification system for most climates and sleep environments.
HumidX Plus
Humidification system optimised for dry and high altitude environments where humidity levels are low, e.g., aircraft.
How HumidX works
When you exhale, heat and moisture is captured and stored within the HME’s tiny paper ridges. When you inhale, this heat and moisture is released to humidify the air you breathe in.

- Small, lightweight and easy to use
- No washing required
- Available in 3 pack or 6 pack sets
