Our Review

best cpap machineThe ResMed AirSense 10 is our winner among the machines we’ve reviewed here because it offers CPAP wearers exceptional value thanks to the built-in humidifier. In addition, the machine is packed with smart technology and the latest comfort features. It’s also one of the quietest CPAP machines on the market today, operating at 26.6 decibels—almost whisper quiet.

While not designed for portability, the AirSense 10 is light enough to go almost anywhere, and it’s small enough to fit in a suitcase. The AirSense 10 With Humidifier is smaller than the DreamStation Auto With Humidifier. The AirSense 10, DreamStation Auto, and all the CPAPs on this list are actually APAPs, which are machines that can automatically set the correct therapy pressure. This can mean fewer trips to the doctor to adjust your pressure, fewer copays, and fewer sleep studies!

The AirSense 10 also comes in a “For Her” model, the AirSense 10 AutoSet For Her, which is designed for a woman’s unique needs. The AirSense 10 AutoSet and the AirSense 10 AutoSet For Her are truly great sleep apnea machines. For anyone looking for a quality home unit, this is it.

Good For:

  • Those Who Like to Track Their Sleep Data
  • Those Who Experience Discomfort During Exhalation
  • Sleepers With Central and/or Obstructive Sleep Apnea

ResMed AirMini AutoSet

Lifestyle NeedsUltra-Portable Travel Machine
Size5.4 in L x 3.3 in W x 2.1 in H

Our Review

Simply put, people love the idea of a small, lightweight, and ultra-portable CPAP machine that can go anywhere and fits in the palm of the hand, which is one of the many reasons why the AirMini is so popular. If you’re a frequent traveler, this is the machine for you. However, due to its small size, it may be louder than your home unit. In addition for most CPAP wearers, the waterless humidification feature is a good substitute for tanked humidification.

Good For:

  • Travel-Friendly: Those Seeking a Portable and Lightweight Machine
  • Those Who Prefer Waterless Humidification

Philips Respironics DreamStation Go

Lifestyle NeedsUltra-Portable Travel Machine
Size5.9 in L x 5.9 in W x 2.2 in H

Our Review

With the advent of the DreamStation Go, Philips created a device with a number of features that wowed CPAP wearers and healthcare professionals alike. The biggest positive in the plus column was the range of battery and charging options, FAA certification, small size, and featherlight weight. The negatives include the fact that it has no built-in humidification and the machine’s noise.

The DreamStation Go is special because it’s the first CPAP machine to have a true color touchscreen display. It also makes use of Philips advanced pressure relief options and includes a slim tube and an integrated battery with fantastic run times. It’s a frequent traveler’s dream, and one you can take on the road easily.

Overall, there’s a lot to like about the DreamStation Go, and it’s easy to see why many CPAP wearers use it for their go-to travel machine.

  • Frequent Travelers
  • CPAP Wearers Seeking a Lightweight Machine
  • Those Who Experience Pressure Discomfort During Exhalation

Our Review

Overall, the Z2 Auto scores 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 updated 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.

Good For:

  • Frequent Travelers
  • Those With Difficulty Exhaling Against Pressure
  • Those Seeking a Ramp Feature

    Can this ever make one feel light headed — especially if the settings are too high– And how to correct accordingly ????

    Thanks for sharing these informations. I am a sleep apnea patient. I am searching for the best CPAP mask. I do not know anything about CPAP mask. Really liked the resmed airsense 10 review. I also agree, all the features of Airsense are really impressive. I can carry this outside also. Depending on the informations shared by you, resmed airsense 10 will be the best for me.

    • Hi Kate, we are very happy to hear that the article was helpful to you in making a decision on which machine may be best for you! Please feel free to reach us at: 1-800-356-5221 with any further questions, or concerns.

      Have a great day!

      • Hello, I just got a new cpap Dream machine it only has blue tooth, I don’t like that so much. And now after using it I started sneezeing and runny nose.

  3. I used my AirSense 10 with a Philips Dreamware full face mask last night for the first time. I’m really happy with the comfort of the mask and am encouraged that I’ll transition to using CPAP in a relatively short period of time.

    My only concern with the AirSense 10 is the cellular communication of data. Without bluetooth, you don’t connect to the machine for data. You rely on the app to connect to your account, which has used a cellular signal to gather your information from the machine sitting right beside you. If you are in an area with poor cell service, that data might not have been transmitted.

    The documentation even says it could take an hour or more after waking for the app to have access to your sleep information. Really? With today’s technology? An hour or more? To gather data from a device sitting right beside you?

    ResMed needs to rethink that for the next iteration of their machine.

    • Hi Greg,

      Thank you for your feedback. I know that it must be frustrating knowing that you may not have access to your sleep data immediately.

      ResMed is always striving to come up with possible solutions to their customer’s frustrations. I reached out to ResMed directly and was advised that the data transfer does take at least an hour to transfer from device to the app, but it has nothing to do with the bluetooth, and the delay is with the machine itself.

      For further questions, or concerns please feel free to reach us at: 1-800-356-5221, or you may e-mail us at: cpap@cpap.com. Also, if you would like any further clarifications regarding the data transferring process, or time periods, you may reach ResMed directly at: 1-800-424-0737.

      Have a great weekend!

    • Hi Greg,
      I suggest you ask your provider to change the Essentials option from On to Plus in the clinical menu. You will then see additional information (AHI, leak, etc.) on the Sleep Report screen while you wait for the MyAir app to update.

  4. Being in the market for a new machine, I was interested to read this article on the best CPAPs. After reading it, however, I’m left wondering if the authors have actual experience with the equipment being written about. It’s hard to know whether I’m just reading a regurgitation of specs with some opinion about them, or a professional review information based on actual use. I was hoping for the later.

    Part of my concern comes from the AirMini review. Much made about the HumidX feature, which is certainly an interesting solution to providing humidification in a highly portable machine. Despite that, I was a bit surprised by the high rating for humidification. I have tried this machine and loved almost everything about it. While the machine itself was pretty quiet, the nature of the HumidX design creates a very loud Darth Vader sort of sound while breathing (at least with the P10 mask I used). For some it wouldn’t be an issue, but it was a showstopper for me. Had I not had direct experience with the machine, I would never have known about this issue from the review. That’s a glaring omission in the article, given it’s a key bit of information that could influence the reader’s decision. It creates a question about what other pros and cons are missing.

    To help inform the reader, please ensure the articles state whether a review is based on third party information or actual use. In the latter case, please include all key pro and cons.

    • Hi AJ, thank you for your feedback. I can totally understand where you are coming from with your concerns. However, the ratings for the machine that you are speaking about AirMini, specifically lists the drawback for the 30 Decibels (noise level) also, for noise the machine is rated very low with a score of 4 out of 10.

      The article goes even further stating that the noise tolerance level varies from patient to patient. Whereas, some folks may not be bothered by the sound level, others such as yourself will see the sound level as a deal breaker.

      This is why CPAP.com offers free 30 day returns on this machine. We certainly have no interest in making any false claims, or no desire to give the illusion that any of our products are rated higher than they actually are.

      Some of our articles are written by professionals, some by researchers and then others by actual CPAP users. If you scroll to the bottom of each article written, you will see a little bit of information about the Author.

      Thank you for your feedback and if you have any further questions, or concerns, please feel free to reach us at: 1-800-356-5221.

      Enjoy your day!

      • Hi Carol,

        Thanks for the response. I did note the decibel rating for the Airmini. With regards to tolerance, I didn’t find the noise level of the machine itself objectionable.

        The design of the masks with HumidX (at least for the P10 I tried) creates a very different noise signature from traditional masks. You’re right that some people will tolerate it, if for no other reason than this is an amazingly compact machine.

        I personally was surprised by how loud the mask was. If traveling with a partner, that could be a deal breaker.

        HumidX is a pretty nice solution to portable humidification and the article provides accolades there. But the noise issue created by HumidX needs to be included as well, in order to inform the reader of an potential issue that goes beyond the machine itself. Especially since the mask is a required part of the overall system.

    I have the Airsense 10. What is missing from all your reviews is quality; as in how long before it breaks. You should have done the work required to speak to the repair people because the Airsense 10 is well-known, and infamous among CPAP techs, to have the humidifier fail within a year.

    So the CPAP devices that have a separate humidifier, or another technology that doesn’t require an ability to steam water, has a clear advantage in the real world. Moreso once you realize that your $900 CPAP machine is gonna give you a sore throat every morning once the humidifier inevitable fails. And getting it replaced, even under warranty, takes weeks.

    • Hi Pat, i’m sorry you’re experiencing issues with your Airsense 10 with built in heated humidifier. It is not our experience that humidifiers fail with the AirSense 10, or any other, within the warranty period. While certainly it can happen, it is not the norm. At CPAP.com, we do as much troubleshooting over the phone to diagnose what the issue is with the machine – In some cases, our warranty period can be less than a week turnaround, and of course we offer loaner machines during this time, if they are needed.

      That being said, for some people the ability to simply remove and replace the humdifier can be an added benefit – though, truth be told, sometimes its harder to troubleshoot because the issue is actually with the machine itself and not the humdifier.

      Did you purchase your machine from CPAP.com? If so, I will be more than happy to assist you with any technical concerns that you have. Please contact us at: 1-800-356-5221 and ask for Carol.

      Have a great day!

  6. Hi, I’m looking to replace my CPAP and I would like to have an every day machine which I can use in several travels I must make every year. Is this machine souhaitable for everyday use?

    i have been diagnosed to have OSAS recently. I am from India and i have met a person with nidex cpap machine ( SEFAM) made in france, and taking its demo. any idea how is the machine.

    • Hi Dr. Sonu Sharma, my apologies, but I’m having trouble with locating a Nidex CPAP machine. Please provide additional details about the machine (ex. model number, name of machine, manufacturer).

      For further questions, or concerns, please reach us at: 1-800-356-5221, or you may e-mail us with additional information at: cpap@cpap.com.

      Have a great day!


    I will offer this warning to persons that may travel or even relocate and are looking at the Resmed. We purchased the Resmed 10 Auto and found the machine to be excellent as well as quiet. The service where we purchased the product was knowledgeable and outstanding. We moved from Canada to the US less than a year into its use. After a month here, the machine developed a wheezing sound, that according to online searching is quite a normal occurrence. The machine came with a 2-year warranty, but no one here will do the over the counter exchange while the machine is being serviced. The lack of after-service assistance is unacceptable. Because of this issue, I would not recommend this machine to anyone. They’re after purchase assistance is non-existent!

  9. Is this a review that only uses specs from the manufacture/box/Internet. Has your staff tried these?

    • Hi Dan, the article is providing information from first hand knowledge. We do trial the machines, but the information is based on customer feedback also.

      For further questions, or concerns, please feel free to reach us at: 1-800-356-5221, or you may e-mail us at: cpap@cpap.com.

      Have a great day!

  10. I order a clap cleaner from common on 5-15-20 and have not received my cleaner yet order #1256 and paid 64.95 I can’t believe I have not received it

    • Hi Mary, I’m sorry to hear that you haven’t received your order after such a long period, but please contact the company you placed the order with for an update on the order status.

      For other questions, or concerns, please reach us at: 1-800-356-5221.

    I’ve been on PAP therapy for over 20 years and I’ve had several different machines, including CPAP, BIPAP and BIPAP ST. Now, my doctor wants me to use an ASV, to help with my CSA.

    I have to agree with the rankings of the brands of the PAP machines ranked by this website.
    I’ve always had ResMed brand of machines, with the exception of my BIPAP ST, when I thought I’d try to try something new. I chose Phillips Respironics Dream Station. Not only was it huge, taking up much space, the machine did not have an automatic on/off feature, once the mask is applied and removed. For compliance reasons, I love that feature on the ResMed Air Curve 10. The Dream Station power button also needed to be held down for a few seconds to power on/off, which was very annoying. Lastly, the supplied hose material had very thin plastic and ripped much to easily. It was a horrible experience.

    I was able to return it and go back to ResMed, which has.much better features, reasonable size and better materials, by far. If you’re unsure which brand to buy, always go with ResMed. You won’t be sorry…
