The Heat Moisture Exchange Unit for CPAP Machines from Human Design Medical is a portable device designed to provide moisture during CPAP therapy. The unit fastens to a simple mask elbow in order to take in heat and moisture from the user’s exhaled breath. Then the moisture is returned into the air stream for inhalation to help prevent dryness.

The universal, travel-sized humidification device can be used with any CPAP, APAP, or BiPAP machine. Additionally, the HME is a replacement part for the Z1 Travel CPAP machines. Both the HME device and the Z1 Series machines are manufactured by Human Design Medical, making the pairing a perfect fit.

HME Compatibility

Machine: The Heat Moisture Exchange Unit for CPAP Machines is universal, and it is compatible with all CPAP, APAP, or BiPAP machines, with the exception of the AirMini™ AutoSet™ CPAP Machine.

Mask: When selecting a mask, please note the Heat Moisture Exchange Unit for CPAP Machines will not work with masks that have a short tube extended from the mask frame, such as nasal pillow masks. It is also not compatible with the Dreamwear masks, as the elbow is not close to the nose. The HME must be very close to the moisture of exhaled air to function properly. It must be connected to a mask with a simple elbow in order to give optimal results.

There are two different size openings on the heat moisture exchange unit. The wider opening is designed to connect to the mask, while the thinner opening connects to the long hose attached to the machine.

Manufacturer testing has shown the heat moisture exchange unit can be used for up to seven nights before being replaced.

This is the HME only and does not include any other machine parts.
