HumidX heat moisture exchangers (HME) are designed to provide you with waterless humidification when you're using therapy.
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.
You can choose between a 6 Pack or a 3 Pack of HumidX F20 capsules for use.
These are expected to last approximately one month befor a chnage is needed
The HumidX for the F20 only comes in standard and not the Plus which is available for nasal and pillows versions
