The Extraordinarily Light Z2 Auto CPAP Machine

This Ultra-Small and Lightweight Z2 CPAP machine is perfect for travel just like its predecessor the Z1 CPAP machine.  This machine weighs only 10.3 ounces and is just 6.48" X 3.30" X 2.02" and easily fits into any carry bag. It also includes an Auto start and stop feature and a free Q- Lite to muffle any noise in the mask area. Not only is this machine light and quiet but you can use any mask with this machine so take your favorite mask with you when you travel!  Need humidification, no problem, this machine offers tank-less humidification through their Heat Moisture Exchanger or HME, which recycles heat and moisture from your exhaled air so no need to bring distilled water with you when you travel. 

The Z2 offers the same great integrated battery options as the Z1 for off-the-grid travel where the power is limited you can add the optional PowerShell which is sold separately

Read How to Travel with a Z2 Travel CPAP Machine

Travel-Friendly Machine

HDM's Z2 is built with the traveler in mind, weighing just under a pound. it will easily fit in a backpack or suitcase and won't take up much room on a nightstand or in a tent. 

Z-Breathe Exhalation Relief 
The Z2 Auto Travel machine comes with comfort features you will find in any top-notch CPAP machine.  The Z-Breathe Exhalation relief function reduces air pressure during exhalation making it much easier to breathe against the incoming air.  The Z2 offers 3 levels of Z-Breathe for your comfort and you will be able to select which level is best for you. 

Automatic Altitude Adjustment 
Ideal for users traveling through the mountains, the Z2 APAP machine was built to automatically detect altitude and adjust the therapy pressure accordingly.  The machine is capable of operating from sea level all the way to 8,000 feet above sea level. 

Leak Compensation
The Z2 CPAP is capable of detecting minor leaks from your CPAP Mask.  When you experience a mask leak, the device will kick in to ensure that your prescribed pressure needs are met.  Should an excessive leak occur, the screen will warn you that your mask is leaking with the word "REMINDER" shown in bold. To remove "REMINDER" from your screen,  simply adjust the mask back into the proper position. 

Using Bluetooth
To use Nitelog with Bluetooth,  you'll need to download the free app from the app store on your iPhone or Smartphone. To turn Bluetooth on, simply unplug the power adapter from the machine, and then plug it back in while holding the up arrow button on the device. Once Bluetooth has been activated, the display menu will indicate "bt-On". To turn Bluetooth off, you can either put your device in airplane mode or do the opposite of what you did to turn it on in the first place: unplug the power adapter, then plug it back in while holding the down arrow button.  If you've done it correctly, the display screen will indicate" bt-Off".

Subject: The NiteLog app can lose data if you change timezones!
The Z2 is a "travel" APAP, but when you travel and decide to check your compliance data, the app asks if you want to change the device timezone to match where you are currently located. You say to yourself, "Sure! I should do that".
Well, ..just don't!
If you do change time zone, then all the compliance data history on your iOS device app gets wiped and starts over as Day 1 for the new timezone. If your job requires compliance data reports then you're going to show a hole in the data when you travel and make the mistake of changing timezones. This is weird bug for a "travel" unit.
Otherwise, I find the unit to be very effective, lightweight, quiet, and comfortable to use. Without the software bug I'd rate it a 5

Subject: Z2 Auto CPAP
I was excited to have a travel APAP machine that would be easier to transport than my Philip's Dream Station. That was until I actually used it! I assembled it properly and my nasal mask was snug, but even if I managed to fall asleep, I would wake up after an hour or so and be unable to go back to sleep because of the noise level. I tried to use it 3 nights in a row without any success. It never occurred to me that this would be an issue and it would be nice if the company could make some kind of modification to alleviate the problem.

Hi Laura,
We're sorry to hear this! Travel units are louder than home units because there is less room for sound abatement insulation.
Have you tried using the Q-lite in-line muffler that comes with the Z2? It will help reduce the noise. This is how you connect the muffler:
machine --> tube adapter --> 8" tube --> muffler --> 4 ft tube --> HME (if using)--> mask

Subject: Nice machine - No bag for travel
I like the product, but for $800, a travel bag should come with it.

Just used my Z2 Auto for the first time on a business trip. It's easy to use, not too noisy, and I like it much more than by Philips Respironics machine that I have at home. Good product!

Are kidding - this price is outrageous This will not be something the average person can afford - what a disservice to clients.

*Thank you for your feedback! We have several different prices of travel machines started at $250 and going up depending on your needs :)

Being a travel unit, I would assume it has the capability to operate off of a 12 volt automotive plug? In other words, does the 110 volt cord on the machine convert and reduce the voltage to 12 volt DC to operate the CPAP?
There is a power brick that can do conversion from 100-240 VAC, 50/60 Hz built in to the power supply. It does not include a DC cable though. There are DC cables that exist for the machine. You can see the cable here: https://www.respshop.com/cpap-supplies/battery-power/hdm-z1-volt-dc-adapter-p-761.html
