Human Design Medical’s Z2 Auto Travel CPAP Machine is proving to be quite popular among CPAP users.
The secret? When compared to its predecessor, the Z1 Auto, the Z2 Auto is 29% quieter and has a different pitch to the motor for optimal comfort. An added bonus? It’s an attractive option for busy travelers due to its lightweight and small stature.
How does it stack up against the competition? Let’s find out!
The Z2 Auto Travel CPAP Machine vs Similar Travel Machines
|Z2 Auto||AirMini||DreamStation Go||Transcend Auto||Z1 Auto|
Noise Level: 7
The Z2 Auto checks in at 26 decibels and is 29% quieter than the Z1 Auto. However, the pitch of the motor is the showstopper compared to the Z1 Auto. The Z2 Auto is whisper-quiet and sounds similar to quiet background noise while you sleep. This change integrates your therapy into your nighttime routine instead of acting as a disruption. The included Q-Tube Muffler dampens the sound further to create a sleeping environment with fewer interruptions.

The Z2 Auto is a little more expensive than the Z1 but is still value-priced compared to similar machines in the travel category. It also comes with a lot of nice freebies like a free Q-Tube CPAP Muffler to dampen the sound and a Heat Moisture Exchange Unit (waterless humidification) to keep your nose and throat from drying out.

The two-year warranty is standard when compared to most CPAP machines. It covers manufacturer defects and mistakes but not misuse or abuse. The Z1 Auto has a warranty of three years, which places it as an industry leader. Ultimately, we awarded the Z2 Auto the same score as similar travel machines that also have a two-year warranty.

The Z2 Auto is so light that you can measure the weight of the machine in ounces and not pounds! It weighs in at 10.4 ounces, which is a nice weight for a travel machine. It weighs roughly the same as the Z1 Auto and others in the travel category. The lightweight of the Z2 Auto allows you to put it in your suitcase or backpack and venture out to your next travel destination.

Pressure Relief: 9
The Z2 Auto tracks your breathing on a breath-by-breath basis and automatically adjusts to your correct therapy pressure. The Z2 Auto adapts to your therapy needs, meaning your treatment will never be one-size-fits-all. The auto-adjusting pressure can also save you a trip to the doctor’s office for pressure adjustments.
Along with auto-adjusting pressure, the Z2 Auto also has Z-Breathe Pressure Relief technology, which temporarily reduces the pressure during exhalation and makes it a breeze to exhale. Another benefit? The Z-Breathe technology will help you develop a normal breathing pattern and increase comfortability. The other machines we looked at also have Pressure Relief technology and auto-adjusting pressure so we awarded them a similar score.

The Z2 Auto includes a Heat Moisture Exchange Unit, which is similar to ResMed’s HumidX. The Z2 Auto recycles humidity from your exhaled breath to create the sensation of moisture without needing water-based humidification. This will keep your nose and throat from drying out. The best part? You won’t have to worry about lugging around a separate humidification system or a tank of distilled water while you’re traveling. Just breathe and humidification is made available!

Smart Features: 8
The Z2 Auto has auto-start and auto-stop features that are similar to the Z1 Auto. Once you put on your mask, the Z2 Auto detects changes in your breathing and automatically starts. When you wake up, the Z2 Auto will sense your breathing pattern change and automatically stop. That’s one less thing to worry about when you’re on-the-go!
The DreamStation Go and AirMini are comparable to each other in terms of smart features, and the Z2 Auto comes very close.

Battery Options: 9
If you’re planning on going off-the-grid or are looking to pack a battery back-up just in case, we have you covered. Both the Z1 Auto and the Z2 Auto have a battery that’s been custom-tailored to fit the needs of both machines: the Z1 and Z2 PowerShell Battery. In fact, the Z2 Auto can use all of the Z1 Auto’s same accessories. This is similar to the DreamStation Go, which also has a companion battery that’s designed specifically for it.
You can connect the Z2 Auto to the Pilot-12 Lite with the Z1 and Z2 Mixed Cable Kit. The Portable Outlet CPAP Battery is also an option, which has the capability of powering any device with a power supply and a plug, making it a versatile and flexible battery.

Overall, the Z2 Auto scored very well across the board and has made a name for itself compared to similar travel machines. Ultimately, the difference in pitch levels and humidification options are the major factors that separate the Z1 Auto from the Z2 Auto. The option of having a quieter machine with the ability to leave your humidification system at home makes the Z2 Auto hard to beat.
