This just may be the best travel CPAP Machine Ever! The New The Z1 Auto CPAP machine builds on the form-factor of the Z1™ CPAP to deliver the world’s smallest, lightest, most integrated auto-cpap machine. At only 10 ounces the Z1 Auto is the best machine that Human Design Medical has released. When integrated with the PowerShell™ Battery Pack, the Z1 Auto delivers an amazing night’s sleep on a single battery charge.

The new Z1 Auto is the world’s smallest, lightest, most integrated auto cpap, with its proprietary breathing algorithm and sampling rate of several times per second it delivers extremely responsive and effective therapy at lower overall pressures than fixed-pressure cpap.

The result is more responsive therapy, a natural breathing pattern, and a more comfortable experience. Simple to use but yet powerful enough to give you the therapy you need.

More natural breathing:

The new auto algorithm in the Z1 Auto adapts to your breathing thousands of times per night to deliver a tailored therapy experience. The result is reduced overall pressures and a more pleasant experience.
  • Learns and responds to your breathing
  • Adjusts itself thousands of times per night
  • Delivers a more natural breathing experience

Super small. Totally integrated:

The Z1 Auto™ is the world’s smallest, lightest, most integrated auto-cpap machine. It was designed from the bottom up to be the ultimate travel companion for sleep apnea travelers.
  • Extremely lightweight at 10.4 ounces/295 grams
  • Fits in one hand
  • FAA approved for in-flight use

Features of the HDM Z1 Auto CPAP Machine


  • Extremely light: The Z1 Auto is the lightest auto-cpap machine available anywhere. At only 10 ounces it is a great everyday machine that is also ideal for travel.
  • Quiet: For a travel cpap the Z1 devices are very quiet. The FDA testing revealed a sound level of 26dB using the standard testing methods although we have heard of slightly louder results from users.
  • Z1 Auto CPAP: The Z1 Auto is an auto-cpap machine that actually adapts to your breathing requirements thousands of times per night. By reacting to your requirements, rather than just delivering one constant pressure, the Z1 Auto delivers therapy at lower overall pressures and delivers a better, more natural breathing experience.
  • Optional integrated battery: The Z1™ has an optional integrated battery system that we call the PowerShell™. It delivers a full night of cord-free power on a fully-charged battery, which makes this a Great Travel machine.
  • Free iOS mobile app for data and remote control: The Z1 Auto is data-capable and records all information on events and compliance. Download the free Nitelog™ mobile app for iOS and sync directly to your device with Bluetooth®. Review your data or share it with your doctor directly from the app. Nitelog™ can also serve as a remote control for your Z1 Auto.

Make it a Z1 Unplugged bundle? You have the option at check-out to add the Power Shell Battery Pack that comes with a battery that will last up to 8 hours at 10 cm of pressure. This machine offers freedom to patients who like to go camping, overnight trips, and other situations where you can't connect to power. The HDM Z1™ PowerShell™ with battery has it covered, giving you the freedom to live your life.

Choose your favorite CPAP Mask... Don't Worry it Is Compatible!

Mysteries Solved. (What you & HDM need to know.)
Phil (USA) 12/2/2017 3:24 PM
Summary Recommendation: First replace the narrow slimline hoses. Get a 1' standard diameter hose for the Qtube muffler in advance. Then run the Z1 15 to 20 hours before trying to actually use it. Then and only then, it be a good travel CPAP. Plus: Small and lightweight. Although the muffler adds a little more bulk, see noise discussion below. Temporary Negative: Noise issue: The outside of the Z1 is very quiet and not the source of the widely reported noise problem. Many have reported a serious noise coming through the hose. I agree, at first there was a loud whirring noise coming from the air supply. Night 1, I could not sleep at all with the noise, and switched CPAPs. Night 2, I got 3+ hours of sleep before switching back to my regular CPAP. At that point, I gave up and resolved to return it. Night 3, I skipped it completely. Night 4, my wife convinced me to try again, and I got all the way through the night. Night 5 was good, and the Z1 did not seem as loud. The next morning, the whirring sound was essentially gone. The rushing air sound was about the same as my older S8 CPAP. So, after 20+ hours of use, the obnoxious whirring noise, had ended. Note that some new motors or blowers will do this till the bearings ‘wear-in’ or ‘run-in’ and the metal to metal bearing friction ends. I believe that is what happened. Improved quality control or a break-in procedure would solve many noise complaints. Qtube muffler: That is marginal at best, and did little or nothing for the whirring bearing noise. After finding and connecting a standard diameter 1' hose, the Qtube seems to help a little with the rushing air sound. Negatives: Air restriction: To make a small system, the small air output and delicate looking adapter are apparently needed. But the narrow diameter slimline tubes are simply stupid in my opinion. I am a 190 lb. adult male with good lung capacity. At first, I found myself inhaling so hard that I was literally fighting for air. (Try this: Stand or sit while holding a good flexable silicone mask loosely with one hand. Run the CPAP and breathe normally. A good cpap will cause slight flexing of the mask. The Z1 flexing / pulsing was tremendous at first.) I got rid of the slimline hoses on both the mask and muffler, and that helped a lot. Once the motor bearings ‘wore-in’, air flow improved to maybe 90% of ideal. There is still some pulsing of the air, but now it is similar to my older S8, and very tolerable. With the mask strapped on, pulsing is hard to detect. The Airsense 10 is so smooth that it makes both the other CPAPs seem crude. But the Airsense 10 is not small or light for travel. After many setting adjustments, it is now set for APAP-2, 8.0 to 9.0 cm, zero ramp. Air Flow bottom line. Get rid of the slimline hose(s), and the remaining small air outlet is not a big deal. Regular diameter short hoses can be found online (try CPAP2U). With a regular diameter hose, and the required motor ‘wear-in’, air flow is good for a large male with good lung capacity. It is not smooth as silk like the ResMed Airsense 10, but it is perfectly adequate for travel. Voltage requirement: At the same time as receiving the Z1, I also received a 12V DC lithium-ion power supply which I wanted to use for power outages. The included HDM 110v AC power supply puts out about 15v DC. 12+v DC from a car cigarette lighter receptacle also works if the battery is good. But below 11.9v DC, the Z1 will simply shut down. The Z1 requires 12v to 15v DC, and do not try to feed it anything less than a full12v. Some of the modern 12v battery operated power supplies do not produce 12v after a very short usage time. Just be aware that a solid 12v up to 15v is needed for DC operation. The overpriced HDM 12v DC plug adapter does nothing to boost or stabilize low voltage to a usable level, but it does have a heavier wire gauge, so that will help a little with a declining 12v battery. I did not try the HDM battery system. Electronics / Reading Data. You can set CPAP vs APAP, pressures (half cm increments), ramp time, and exhalation relief using the machine buttons. The clinical manual can be found online. You Can Not read results with the machine buttons. That is a problem. If you want to read your results, you must connect to a smart phone or windows computer. The Android app is unchanged in 2 full years since it’s first release, and has one of the worst Android App ratings. If you only use the Z1 for limited travel, then maybe reading results is not important. So far, I have not tried either electronic connection, but will eventually do so. Summary: Size and weight are terrific, especially compared to my first CPAP 20 years ago. Noise starts out being terrible. But after 20+ hours of ‘run-in / wear-in’, the ‘whirring’ noise problem ended on this Z1. Ditching the small diameter / slimline hose also helped for noise and was required for air flow. For my wife, there is no ‘outside noise’ issue. The Qtube muffler may not be worth the money or bulk. Air restriction was a problem at first. Again, the blower motor ‘wear-in’ time and conversion to standard diameter air hoses were both required. New out of the box, with the small diameter hose, it was like breathing through a towel or two. Now my Z1 air flow is good, and similar to my older ResMed S8 Elite, but not great like the Airsense 10. Voltage requirements are probably only a problem if you plan to camp or use a backup with an external battery. A full 12-15v DC is required. If you only travel to places with stable AC power like hotels, then this is not an issue. Additional required electronics is a negative. I want to read AHI once in a while, and am not happy a computer and/or smart phone (with a bad app) is required. Final Conclusion: At first, I decided to send the Z1 back. Now after 9 nights of partial or full use, and the above changes, I will keep it. It gets 4 stars because it is so small, light, and yes, now quiet. It will be good for travel, but not as a substitute for an Airsense 10 at home. The Qtube muffler might get returned, and a backup Z1 to air hose adapter will be ordered.

Works OK but hard to use
Carlos Sanchez (Bakersfield, CA) 7/14/2017 1:21 PM
I have used this machine while traveling for about 1 year now. I used to travel with my full size CPAP and this one is smaller and somewhat more convenient. Pros: Smaller, more convenient, it fits in my carry-on easier. Cons: Once you add the tubing, power supply, ducking station, batteries and mask, the smaller size of the machine is not really a benefit. They give you a 4' hose, which is too small. I use the normal 6' hose. The machine slides on top of the night table, which is very annoying. The power transformer has a very bright green LED that disturbs your sleep. The power ON button is the only way to turn the machine on and off. Auto ON is not available. You have to search in the dark for the ON button to start the machine. The ON button is in the middle of the 3 buttons and sometimes you pres the wrong button. Auto ON would be much more convenient. Auto OFF would also be convenient but it is not available. They send you a "adapter" to connect the normal 22mm hose to the machine. It is made of plastic and it broke making the machine useless during the trip and until I got a new one I had to tape the hose to the machine directly. That made the "travel" part much less convenient. I have no idea what the UP/DN arrow buttons do. Nothing as far as I can tell. BTW, the manual is useless. Conclusion: It works but it is not worth buying it unless you need an inconvenient second machine for $800.

Positive Review
RD (USA) 3/10/2017 10:52 AM
I was hesitant to purchase the z1 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. I got used to it pretty quickly. Importantly, it works and works well. I have been on the road for two weeks changing hotels almost daily and loading up on an airplane. I can get the Z1 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 for the first time had a good look at how my CPAP actually works during the night. 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 z1 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. This is a great product.

Small but loud
Michael (Australia) 9/30/2016 7:27 PM
The CPAP is as small and neat as it looks. The integrated power supply is also excellent. However it is rather noisy in comparison with other travel machines I have used and i have found it difficult to like for this reason.
