Your Z1™ and Z2™ includes a complimentary Heat Moisture Exchanger (HME) to provide humidification during therapy. HME technology has been in use for over 50 years and is now available for your Z1™ and Z2.

The hygienic, disposable HME works by capturing heat and moisture as you exhale and provides it back to you as you breathe. The HME does not use any electricity or complex moving parts and avoids the problems encountered with electrical humidification systems.

HME’s are designed for travel and should be replaced after up to 7 nights of consecutive use or when it is no longer providing the needed humidity. 


To install a Heat Moisture Exchanger for therapeutic use, connect the large diameter end of the HME to your mask and the smaller diameter end to your CPAP Tube. Be sure both connections are fully seated and secure. Your HME is now ready for use.
