ResMed HumidX F20 (3 pk)

HumidX capsules for AirFit F20 or AirTouch F20 full face masks. Each one provides waterless humidification when used with a ResMed AirMini CPAP machine.

They work by capturing heat and moisture within tiny paper ridges when you exhale. They then release this heat and moisture to humidify the air when you inhale.

This is for a 3 pack
