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.

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.

Special Features

  • Lightest travel CPAP Machines: Weighing only 10.4 ounces, small enough to fit in the palm of your hand and conveniently in any suitcase or bag.
  • Auto Start / Auto Stop By Simply placing the mask on your face, the therapy will start when the device senses that you have started to breathe. When the mask is removed or there is a leak detected the Z2 will stop within seconds.
  • Z-Breathe Pressure Relief: Z-Breathe is a comfort feature making it easier to exhale temporarily reducing the pressure during exhalation. This helps a person have a more normal breathing pattern and makes it more comfortable to use. Z-Breathe has 3 settings so you can set it to suit your own personal needs.
  • Ramp Feature: The Z2’s Ramp feature allows you to start your pressure at a lower setting and ramp it up over time to let you adjust more gradually to CPAP therapy.
  • HME – Waterless Humidification: The Z2 comes with a small, portable humidification cartridge called an HME (Heat Moisture Exchanger). Inserted between the hose and the mask, it captures the moisture in the exhaled breath and releases it on the inhaled breath. does not require electricity or water.
  • Reduced Noise: The improved Z2 motor and firmware combination, along with the included Qtube, are designed to minimize both dynamic and static noise at the device and within the mask.
  • Power Supply: When traveling abroad the power supply automatically adjust from 100 to 240 volts. All you need to add is the proper plug adapter for the country you are visiting.
  • Optional Power Shell: The Z2 Auto CPAP is fully compatible with the optional integrated battery system called the PowerShell®. It delivers a full night of cord-free power on a fully-charged battery. The Extended Life battery is a rechargeable lithium ion battery that you can charge during the day for a night’s worth of therapy. The PowerShell is great for travel where power is limited or even off the grid.
  • Nitelog App Download the free Nitelog® mobile app for iOS or Android and sync directly to your device with Bluetooth®. Review your data or share it with your doctor directly from the app.
  • Auto-adjusting pressure: The Z2 measures breathing on a breath-by-breath basis and automatically adjusts to the correct therapy pressure.

  • FAA Compliant.

  1. Verified Customer

    Excellent – works like a dream (pun intended). Quiet, easy to travel with.

  2. Verified Customer

    I purchased to go camping but now use is all the time. Even though I am a Cpap user I have is set to change with my breathing and I feel I sleep better. To me, not any noisier then the machine I have now. I recommend you give it a try

  3. Verified Customer

    Nice portable size. It is not that loud. This will make traveling easier. I won’t have to lug my main machine everywhere

  4. Verified Customer

    This is my second Z series travel cpap, and I got a second one because I liked the first one so much!! I only gave it four stars because they still haven’t worked out the noise issues. Having said that, I hasten to add that the noise isn’t really bad at all, it’s just that I fail to understand why there’s any noise at all!! I truly love that it’s so small

  5. Verified Customer

    Great size and ease of use. Length of hose is fine. I did not get a battery unit. The noise is reportedly the same as my air sense but seems a little louder than that. I use white noise anyway so no big deal to me. The real sell for this was the travel size and ease of use. I travel very frequently and this will be much easier than lugging my air sense around. Still new so have many nights of testing ahead of me. So far so good

  6. Verified Customer

    Only tried it a couple of nights…works well. Was concerned about the noise, but with the included muffler, it was not really noticeable to me, although I do have a little hearing loss at my age (70). The transfer of data using bluetooth seemed to be a bit slow. The only drawback I can see is during long term useage and having to replace the humidifier module at about $5 per unit. They are supposedly only good for 5-7 nights. Don’t have the optional battery since it is a bit pricey. There is a 12 Volt adapter available, but it’s listed to charge the battery. Don’t know why it wouldn’t run the cpap too

  7. Verified Customer

    The Z2 unit itself is great. I was worried it would fall off the nightstand but when used with the battery pack it’s heavy enough to stay put. The only major downside is the number of parts. I fear that travelling with this many separate parts something could get lost or broken. My biggest fear is breaking or losing the small plastic adapter that connects the unit to the first hose. I wish it was like other units, that connect the hose directly to the unit. Otherwise, unit works well and is quiet. A second, minor concern is having to remove the Battery pack so it doesn’t discharge, but that’s a minor inconvenience that takes up space.

  8. Verified Customer

    The Z2 is a replacement for my Z1 that needed repair. I’ve tried it out and love the fact that all of the parts from the Z1 fit the Z2. I especially appreciate the upgraded feature of the auto start – just like my regular auto pap at home. I have been pleasantly surprised by home well the HE devices work. The Z1 has lots of travel miles on it and I’m expecting the same great sleep with my new Z2.

  9. Verified Customer

    I am very happy with my Z2! My travelling has become so much easier. I did not have any issues with machine or setup. It is a bit louder than my regular machine however it did not inhibit my sleep at all

  10. Verified Customer

    Love my new Z2…perfect size and absolutely quiet. Use it on the road and at home. Travels well! Worth every penny spent

  11. Verified Customer

    I bought this to replace my old travel cpap. This Cpap far exceeds my expectations! I took it on a weekend trip and found it very quiet and easy to use. I just put it on the bed next to me and the shorter hose was more than long enough. Also I found I didn’t need the extra moisture, it worked great without it.. I am very happy with my purchase!!!

  12. Verified Customer

    This is an outstanding product for travel use – it is so small, works perfectly, and is very quiet, so I am very pleased

  13. Verified Customer

    This is a nice travel machine, compact with attachments. Not as quiet as a house machine but you should not expect that it would be. For what it is designed to do it does well. I am going to buy another as spare

  14. Verified Customer

    As a 20 year cap user, this is my 3rd travel machine and 6 machine overall. This machine is very small and quiet. The moisture recapture device works for me. I have tested and can get 2 nights sleep from one full battery charge. I have a friend who has another brand of travel that doesn’t allow battery power and that would not work for me as I backpack Customer service is always knowledgeable and helpful and deliveries are quick. Long time mirage swift user. Good mask.

  15. Verified Customer

    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 purchase the Z2 Auto again

  16. Verified Customer

    I’ve used a cpap for many years and needed a smaller travel cpap. After reading reviews and features I decided on a HDM Z2 in part because of its compatibility with standard hose and masks. My (lifetime) prescription was already on file at . I received the box several days after ordering. The unit is small and quiet. With the Qtube muffler it is *very* quiet. I’m considering purchasing a 6′ hose instead of the 4′ one included. Also plan to buy a small padded case for the device, power supply, hose and mask because it did not come with one. I’ve tested for a couple of nights and am so far very pleased

    I have been using it a week and the size is great. It makes a funny high pitched sound for about 30 seconds when I start but after that QUIET. A big plus, but it does not have a true humidifier and I realized I really prefer the real deal. My mask will not accommodate the self-humidifier using your breath. It works well but like a real humidifier. I am keeping it for travel. It works great and I slept well with it. I recommend it.

  19. Verified Customer

    I never before even considered taking a machine with me when I traveled. This is small, light and easy to take anywhere

  20. Verified Customer

    So far this product is meeting all my expectations. It is quiet, easy to use and provides all the stats I need. I probably would use it full time if I had an humidifier with it. At this point it is my go to travel machine. I noticed one small glitch this morning. When crossing months it didn’t seem to record data properly

  21. Verified Customer

    I do a lot of RV camping and don’t like to take my home CPAP because of size and possible water mess from the humidifier. I always wanted to try a travel CPAP but have never had luck using one without a humidifier. I saw this one provided humidified air without a water chamber and thought I would give it a try. To my surprise it worked great. Been using it a week straight while camping at the beach and have had no problems. If you have the same concerns as I did, give this one a try.

  22. Verified Customer

    It is a little noisier than the Air Mini but that may be because, combined with my mask, there is a higher air flow. However letting me use my preferred mask, instead of the nose pillows, makes it MUCH better

  23. Verified Customer

    I use my home machine with a 12 volt adapter in my truck camper. This works fine, but I wanted to get back into backpacking and needed a smaller lighter machine. I also was looking for a 12 volt machine. I think the z2 is the only one that is 12 volt. Most others are 24 volt. It should use less battery than my home unit The machine works well and I purchased the medstrom 12 volt battery to go with this machine, instead of the proprietary z2 battery system for a few reasons(see review on battery page). The features of the z2 are the same as my home machine and performs the same. It is a bit louder, but not bad at all. the supplied muffler tube helps alot in quieting it. It dosnt have a humidifier. Most travel machines dont. U cant use the heater and humidifier on battery anyway. It would use 4 or 5 times the battery if you did. So I dont use that feature while camping anyway. I find I dont use the humidifier or heater in the summer months becouse of the humidity level in the air. I did purchase the small inline humidifier filter thing, but haven’t tried it yet. Very happy with the system. With the machine, battery, mask, hoses and cords I was a litle over 3 pounds. I was able to get 3 nights with this system all 3 nights were 8 hours

  24. Verified Customer

    I love to travel and have used a Cpap for over 15 years. My children lived out of the continental US. I bought machines to leave at their homes to avoid the clumsiness of toting a machine through the airport. I have looked at purchasing a mini machine for several years but just couldn’t go that extra step of expenditure. So now I wait until travel is severely curtailed and bite the bullet- go figure! I LOVE IT – the size is great – I was concerned about noise level based on different reviews so specifically selected the Z2 with the help of Steve in customer service. It is white noise if anything. I never camp or backpack so the need for a battery was not priority but maybe later! Don’t wait – you will not regret your purchase

  25. Nick

    I have had a Z1 for 6 years. It was great for traveling. Recently I purchased the Z2 model. The Z2 is a significant update to the Z1. I have used the Z2 once so far and I am more than pleased with the Z2. The auto feature is really nice. The machine seems quieter than the Z1. I am looking forward to using the Z2 for years to come

  26. Verified Customer

    Love it so far. Whistles a bit but I think I will get over that.

  27. Verified Customer

    Previously, I used Z1 auto. Z2 auto is a big improvement of Z!, it is much more quiet. All the bugs of Z1 were rectified.

  28. Verified Customer

    works well on first night

  29. Verified Customer

    Great product to bring on your travels. Tucks away in any bag.

  30. Verified Customer

    Easy to set up and quiet when I was using it. This is so much nicer than packing and toting my regular machine. I’m glad I bought it

  31. Verified Customer

    Size is much more manageable than standard cpap machines for travel. I gave it a test run at home ,seemed to work well. A little more noise than my full size but not terrible. I will know better when I’m back out on the road again. A travel case included would’ve been nice though

  32. Verified Customer

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

  33. Verified Customer

    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.

  34. Jenny Davis

    Excellent! Was lucky enough to pick one up just before restrictions ended and we have been travelling Victoria with it and i love it! It’s so small and the little battery is perfect. You can even charge up your phone using it. It all packs up in the neat little bag and is very easy to use. It turns on and off automatically. Very happy to recommend it to others. Works great with my ResMed Nasal pillow p10 mask

  35. Verified Customer

    I frequently travel for work. This unit has served me well in North America and as I travel thru Europe

  36. Verified Customer

    had a first generation Z1 and although pleased with the compact size, I was disappointed with the noise level (as was my wife…). The Z2 delivers the same travel convenience and is quiet enough to even use daily. A significant improvement and definitely worth the investment for travellers

  37. Verified Customer

    So far the Z2 has worked well, just as advertised. It’s great for travel! Thanks to Nick for the great Videos.

  38. Verified Customer

    Very very satisfied with product And the company . Highly recommend.

  39. Verified Customer

    The size of the machine is as advertised and will be very convenient for travel. Set up is intuitive. I was surprised the setting is 4cm as that is not my prescription however it is advertised to change to the needed pressure through out the night. It is louder than my home machine but not so much as to disturb sleep. Got what I asked for, reasonable price. Would recommend to others

  40. Verified Customer

    Good for traveling due to small size and working fine. Strongly recommended to travelers

  41. Verified Customer

    Run on 12 volt. Don’t need converter. Soooo quiet. HME provides moisture.

  42. Verified Customer

    I purchased the Z2 Auto CPAP for my husband who is a frequent traveler. It arrived the next day as I was packing up to leave by noon. I wanted to make sure that he would be able to operate it so I called CPAP, and they talked me thru set up and setting , 3 times????. He LOVES IT! I call it “Mini Me”. We have 2 other employees who have purchased them as well. We give the Z2 5+

  43. Verified Customer

    I have been using my new Z2 Auto Travel CPAP Machine for 2 weeks and love it! It is so quiet and lightweight. I can’t wait to take it with me traveling. I should have bought this years ago.

  44. Verified Customer

    I bought the Z2 Auto Travel CPAP Machine about 6 months ago for use on an overseas trip. My regular machine just takes up too much space in my luggage. Before I made the purchase, I read all the reviews and I wasn’t sure if it would really work well for me because 1) no humidifier and 2) the filters were expensive. I bit the bullet and made the purchase and I gotta say that I am 100% satisfied with it. I love the small size – it’s abut the size of large TV remote & probably twice as thick. I just place it on my bed each night. The hose is short but with the machine on the bed, it’s plenty long enough. It came with a MUFFLER because some people claimed it was too loud. I didn’t like the Muffler because when it is connected to your hose it is uncomfortable to sleep with and it is heavy. I removed this piece and discovered the machine is not loud at all -but that is just me. (no louder than my full-size CPAP) Now I hesitated about this purchase because of the cost of filters….$5.00 ea. and only good for about 5 days. I mean, why didn’t they make them so you could just pop that sponge out and wash it and re-insert it??? Well let me tell you that is exactly what I did!! I used a skinny, long piece from a water pick (I used the rounded, blunt end) and pushed that sponge right out of the filter housing which is a hard, sealed plastic case. I washed it, and let it air dry. Then I used the same poker and pushed that sponge right back into that hard plastic case. It was easy & it popped right into place. (there are holes on either end of the plastic case. I guess you could use a cotton swab, anything thin & strong enough to push the sponge in and out without damaging it. There are holes on either end of the filter. On one side the opening is larger than the other. I pushed from the small hole through to the larger hole. I only purchased 2 filters because I figured I would only use the machine when I traveled or went camping. These are good big sponges so I figure they will last for awhile as long as I remove, clean and sterilize them (in vinegar water). I love my Z2 Auto Travel CPAP so much that I am using it almost every night, it’s so comfortable. One more thing….I haven’t missed the humidifier at all. I thought for sure I would have a dry throat in the morning but never did. I am so glad I made this purchase. Now I am saving up to buy the battery that goes with it. LOVE MY Z2 AUTO TRAVEL CPAP!!!

  45. Verified Customer

    Used machine for 4 days, couldn’t ask for better service. Noise level is low and size is very good for travel. I would recommend for people looking for a good travel unit

  46. Verified Customer

    Nice machine, quick and simple to assemble/disassemble. I’m sure I’ll get a lot of use from it once it’s safe to travel again.
