Product Details

The New Z2 Auto CPAP Machine is an improved version of the Z1 Auto travel CPAP machine. The Z2 has an improved quieter motor with 29% less noise at the air intake than the original Z1.

This travel CPAP comes with a FREE Q-Tube to further reduce noise, and if you are not completely satisfied with this unit, return it within 14 days of purchase for a full refund! CPAP therapy on the go has never been easier, weighing at only 10 ounces makes it easier than ever to fit in any suitcase or bag.

Small but Powerful, the Z2 APAP machine can flow 4–20 cmH2O of pressure, satisfying the prescribed levels for most obstructive sleep apnea patients. The Z2 also utilizes HDM’s comfort-enhancing Z-Breathe™ technology, a proprietary algorithm that lowers CPAP pressure during exhalation based on your breathing pattern.

No special mask required: The Z2 Auto does not require a special mask or tube for use. You can use your favorite mask as long as it does not have a proprietary connection.

Integrated Battery Option: For travel off the grid or where power is limited, add on the optional PowerShell® with New Extended Life Battery at Check-Out, for a fully integrated battery option. The PowerShell’s Extended Life Battery is a rechargeable, lithium-ion battery which provides a full night’s therapy on a single charge. The Battery can be used only with the Z1 and Z2 Travel machines.

    I fly in and fly out for work and this machine has served me very well. You hardly even know it’s in your luggage. Has a smaller 4 ft tube but i switched it to a 6 ft as i prefer a bit more length. Very happy

    Purchased the Z1 Auto for a trip to the Kimberly and i love it! It’s so small you barely notice you have it with you. The battery system was perfect for nights when we had no power access and we were able to charge the battery from our 4wd as we drove from place to place. The machine is easy to use and operate. The noise level is slightly higher than my ResMed unit but not by much. I have a pressure of 9cm

    Perfect for hiking! We also got a medistrom 12v battery which we charge via solar whilst hiking. It takes about 6-7 hours to charge but it means you can go places where there is no power which is exactly what we do. The machine is super small and works perfectly. We just put it in the back pack and away we go. Delivery was fast (next day). Thank you

    I was hesitant to purchase based upon its small size – could something that small actually work – and the reviews about the noise. I ultimately purchased it anyway because I needed a lighter, smaller travel machine. I could not be happier. It is louder that my bedside CPAP but it is not nearly as loud as I feared. Importantly, it works and works well. I have been on the road for two weeks changing hotels almost daily and loading up on a plane. I can get the Z2 assembled or take it apart in less than a minute. It is small and light. It works well. The nitelog was a pleasant bonus. I downloaded the app and the first time had a good look at how my CPAP actually works. As an engineer that was more than interesting to me. I do one thing slightly different. I put the mask and electrical in the gray bag and I found another small bag to hold the machine itself. That lets me arrange them in my carry-on a little more conveniently. All-in, I was pleasantly surprised. I was a skeptic.

    I’ll give this product an overall review a 4 out of 5 stars for quietness, 5 stars for it’s size and convenience. Overall the product works as intended and expected the level of therapy is the same as my bulky home unit. I purchased this unit for traveling if you don’t mind the white noise but enjoy the convenience and space in your suitcase then this product is for you.

    Product seems to be just what I needed for traveling. Very small compact unit.

    Was expecting the only benefit from the Z2 to be its size for travel. The machine is much quieter than the reviews said. In fact it is quieter than my full sized ResMed machine. The Heat Moisture Exchange Unit is great. You don’t have to mess with water and the is no moisture on my face when I wake up. Downside is that you have to replace them! I would definitely recommend the Z2

    So far I love this machine…it is light and easy to use. I am very satisfied with what I received…very quiet and I am eager to use it on my next trip. This will be the first time having such a small unit it will be a pleasure to carry.

    I use a ResMed AirSense 10 AutoSet and was tired of lugging it around when traveling by air, so I wanted a smaller machine for travel. This manufacturer was recommended by my sleep doctor. I purchased the Z2 because it was supposed to be quieter than the Z1, and I used it several nights to test it. It is definitely not as quiet for me as the AirSense, but I did get used to it. My husband has not been bothered by the Z2’s noise in the room. I use a Dreamwear Nasal mask and had no problem with it. I did not use the Heat Moisture Exchange Unit. This fits nicely in my carry-on bag, so I’m looking forward to better travels.

    We are frequent travelers and the size of this machine is great. Tried it the first night and it made more noise than my regular and very quiet machine. However, it must be white noise as by the 2nd night I slept soundly. I do miss being able to use my usual wisp mask as the ones compatible with this machine are not as sleek nor as comfortable. However, I have overcome the noise and mask size and am looking forward to packing up for our next trip.

    Trucker from S.A this unit has been a godsend! Plugs directly into my 12v plug and runs like a dream! Unbelievably small which is great for the truck. Also very handy for holidays and travel. Cheers

    I was very sceptical that something so small could provide me with the same pressure settings that my large Resmed machine does but it has performed very well! It’s around 1/3 the size and weight which makes it very convenient when your going through airports etc. It’s also surprisingly quiet as i was under the assumption the travel machines are noisy. The only downside was the lack of a travel bag. Hopefully they introduce one in the near future. I’m a happy camper

    Positives – Incredibly small and light weight, easy to operate, pretty quiet, 12V options (very handy!), can use my own mask.

    Negatives – The 4ft tube is a bit small. I purchased a 6ft one for $20 online.

    I have taken it overseas twice now and it’s so much easier than travelling with the big clunky one. You don’t have to worry about different voltage overseas and you can use the battery system on the plane for night flights. Very cool

    I have both the Z1 and the Z2 and the Z2 is definitely quieter. The only thing i wish it came with was a bag but you can get any camera bag to suit. I use it with a ResMed P10 mask which is also very small and light weight. Have taken it overseas many times now and it’s very simple to use. Thank you
