Heat/Moisture Exchanger (HME) for the HDM Z1 and Z2 CPAP Machine
A unique alternative to bulky water based humidifiers, HME Filters capture heat and moisture from your sleep therapy air and exhalations, preserving and increasing humidity to prevent your airways from drying out during CPAP therapy. HME Filters are a great option for travel or battery powered CPAPs where a traditional heated humidifier may be impractical.
The Heat Moisture Exchange Unit for CPAP Machines cannot be cleaned. The manufacturer suggests replacing the unit after using it up to seven nights.
