Exclusive to AirMini, HumidX are small heat and moisture exchangers (HME) that are designed to provide comfortable and effective humidification.

How HumidX works

HumidX is a waterless humidifier that’s designed to provide you with more comfort by retaining the moisture and heat in the air you breathe, and offering relief from possible dryness and congestion. 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.

HumidX can be inserted directly between the mask connector and the vent, providing effective waterless humidification at a compact, effective and comfortable level. 

Please be advised each HumidX lasts for 30 days once it has been opened out of its packaging.

HumidX Plus is also available for use in dry conditions, including aircraft cabins.

HumidX is part of the following set-up packs:

  • N20 AirMini Set-up Pack
  • P10 for AirMini Set-up Pack
  • AirFit N30 mask pack for AirMini users

*Available only on AirFit N20 nasal mask, AirFit P10 for AirMini nasal pillows mask and AirFit N30 nasal mask for AirMini.

Please refer to the user guide for relevant information related to any warnings and precautions to be considered before and during use of the product.
