ResMed AirCurve™ 10 VAuto BiLevel Machine: A Complete Review

Table of Contents

If you were a ResMed S9 user in the past, you may love the new, advanced AirCurve™ 10 VAuto BiLevel Machine with HumidAir™ Heated Humidifier.

This model automatically adjusts on a breath-by-breath basis to deliver separate air pressures for inhalation (IPAP) and exhalation (EPAP). Users of the S9 machines may appreciate some upgraded humidification options ResMed has added by integrating its HumidAir™ heated humidifier—which can auto-adjust humidity levels based on the temperature of the room air—and the ClimateLineAir™ optional heated tubing.

In addition, the AirCurve™ 10 offers pressure relief technology to help mimic natural breathing and offers a special, advanced tool to help people with chronic breathing problems like COPD: the TiControl feature, which monitors the pattern of inhalation and exhalation to help prevent cycling.

These are just a few of the top-shelf features this sophisticated and popular machine offers. A whopping 37% of our BiLevel machine buyers select this model, for good reason: it comes with great comfort and convenience options and users say it provides an excellent night’s sleep. Says one user, “This is a huge improvement over the S9 series.” Another says, “I was a little hesitant to replace my S-9 VPAP, but this machine performs flawlessly and exceeded my expectations.”

To learn more about the ResMed AirCurve™ 10 VAuto BiLevel Machine and whether it might be the right BiLevel apnea machine for you, keep reading for a breakdown of the details and features.

Optimized Humidification with Climate Control

Humidified air is important to keep therapy comfortable and sinuses healthy. Recognizing this, ResMed designed the AirCurve™ 10 machines to include a built-in humidifier. Users can choose whether or not to use the humidification system and can use the display screen on the machine to adjust the humidity level, with 8 different levels to choose from. To further enhance the therapy by warming the air during delivery, ResMed offers an optional 78-inch (6.5-foot) ClimateLineAir™ Heated Tube.

These options are helpful, but what really sets the AirCurve™ 10 machines apart from other BiLevel machines with humidification is the automated Climate Control system. Just select “Auto” on the screen and the AirCurve™ 10 will optimize humidification with minimal rainout condensation, based on readings it takes of the room air temperature. You won’t need to wake up in the night to add or reduce humidity—the machine will take care of this for you.

Advanced Pressure Relief and Comfort Options

Another nice benefit of the AirCurve™ 10 machines is that it’s designed to deliver optimal therapy along with optimal comfort. ResMed uses an algorithm to monitor user breathing during therapy, so inhalation pressure and exhalation pressure can be adjusted automatically while users sleep. This feature, common on autoset BiLevel machines, gets a boost from a few extra comfort features to aid easier breathing:

  • Pressure relief system. If you’re using your machine in CPAP Mode, Expiratory Pressure Relief (EPR™) aids exhalations to bring your sleep breathing closer to natural rhythms. It adjusts pressure relief levels based on settings you choose (Level 1, 2, or 3), or you can shut it off.
  • Ramp. If you’re using CPAP Mode, ramp will incrementally increase air pressure until it reaches the prescribed pressure, so you can fall asleep naturally without feeling any discomfort. In the BiLevel and auto modes, the expiratory pressure will start low and increase gradually to the prescribed pressure.
  • Easy-Breathe. When used in S mode, AirCurve™ 10 offers an optional Easy-Breathe function that mimics the user’s own natural breathing pattern.

And to monitor for leaks, Vsync Technology checks your mask seal throughout the night and compensates by adjusting pressure as needed.

Special Settings for Respiratory Disorders

Perhaps one of the more unique features of this BiLevel apnea machine is the TiControl feature, which monitors users’ breathing patterns and can detect early or delayed changes from inspiration to expiration (called “cycling,” which leads to inefficient breathing). The machine sets a minimum and maximum time limit on inspiration, which helps to prevent cycling. If the user’s breathing is irregular or slow, the machine will alter its timing to deliver air pressure at a different cadence in order to get the user back within set limits. Users with COPD and obstructive lung disease can get more effective and comprehensive respiratory therapy as a result.

Great Choice for Gadget Geeks

Perhaps one of the biggest selling points of the AirCurve™ 10 VAuto is how it feels as an integrated package. Without the humidification chamber attached, the machine itself measures a neat 8”x4”x6”. The rounded front dial, color LCD display, and “Home” button make it resemble a bedside stereo more than a traditional CPAP or BiPAP. Design fanatics won’t be fooled, but this is a sleeker-than-average model, and users frequently comment that it’s more attractive than apnea machines they’ve used in the past.

The color LCD display is a user-friendly addition, with easy to use menus and an easy-grip dial. Navigating and selecting the settings if easy and intuitive. For example, the Mask Fit seal check gives you the “all clear” with a green smiley face or a “try again” red frowny face. You can choose a Leak Alert from the menu of options, and a SmartStart™ function enables therapy to begin as soon as the machine senses you breathing into the mask. These bells and whistles may not be necessary to a good therapy experience, but for users who value instant feedback and guidance about the process, they certainly make the process of adapting to apnea therapy more fool-proof (and more fun).

As for data tracking, the AirCurve™ VAuto records all therapy data on the machine’s onboard memory, which you can download to the included SD card. The machine holds a full year’s worth of compliance stats and keeps detailed data for the past 30 sessions, so users can check on their previous night’s sleep right from the machine’s display.

As one customer points out, “I like that the display gives me immediate feedback on my sleep the previous night – average number of events, number of hours of sleep, data about mask leaks, etc. And if I want to delve deeper into this data, I can log into MyAir and view more detailed data. No more pulling the data card and using ResScan!” Data is also uploaded automatically to the sleep clinic so your physician can review your information.

Considerations (Possible Drawbacks)

Are there any downsides to selecting a ResMed AirCurve™ BiLevel Machine for your sleep apnea therapy instead of a competitor’s BiLevel or BiPAP?

We’ve looked through dozens of user reviews, combined with customer service feedback and the manufacturer’s information. After a full review of the literature, we’ve compiled the following list of factors to consider:

  • The cost. It may not surprise you that this is one of the more expensive BiLevel apnea machines on the market. However, as customers frequently point out, this machine has “all the bells and whistles,” so you do get what you pay for. Fortunately, you can pay on a monthly plan, which makes the cost much more manageable for many people. The product also comes with a 2-year warranty, which is good news when you’re plunking down so much. (As usual, check to see what insurance will cover.)
  • The control screen isn’t very bright. While most customers like a control screen that doesn’t contribute to ambient light in the room, a few customers have complained that this screen doesn’t function well as a nightlight.
  • Operating instructions may be confusing. Most customers love the advanced features and controls of this model. However, some point out that instructions for options like Airline Mode may be confusing. Fortunately, you can call CPAP.com customer service or use the 24-hour CPAPtalk.com Support Forum to help troubleshoot these issues.


On the whole, users report loving this machine, for good reason; it comes equipped with a host of advanced comfort and convenience features, plus it delivers excellent, effective therapy. Though some may nitpick about the finer points of features and whether or not they’re necessary, for the most part, nearly every review and feedback we’ve seen have emphasized that users—even those who’ve used other CPAPs and BiPAPs in the past—slept better after trying this machine for a few days. Is it worth the high price? As one customer points out, since “you spend about 1/3 of your life sleeping, you might want the best possible.”

  1. i like the ResMed products, i just recently purchased the Aircurve 10V Auto and i like it. I do not like humidifier climate control, so i turned it off. The drawback to that is that i have dry mouth after using it for a couple of hours. i can’t stand heated air to breath so i like to turn it off but it creates a dry mouth dilemma. Any ideas for relieving this.

    1. Hi W. Todd Clark, what type of mask are you using? If you are not using a full face mask, you may consider one. Dry mouth is an indication that your mouth is falling open during your sleep. If you are currently using a nasal mask and would like to continue using it, you may consider doing so in conjunction with a Chinstrap.

      Please see the links below for more more information on dry mouth. Please feel free to reach us at: 1-800-356-5221, or you may e-mail us at: cpap@cpap.com.



      We wish you the best!


    1. Hi Nancy, i’m sorry that your AirCurve, machine didn’t work out for you. The ResMed AirCurve 10, is one of the highest quality machines, available. Perhaps, you would have had a more positive experience, with setting adjustments.

      If you would like to speak with us further regarding your machine options, please feel free to reach us at: 1-800-356-5221, or you may e-mail us at: cpap@cpap.com.

  3. First night of using the AirCurve10.
    The Good:
    Quite, smaller than previous units that I have used and very feature rich.
    The Not So Good:
    Have to wonder “Who is designing the IP/telecommunications interface”. Seriously??? Only a cellular interface??? What happened to WiFi??? My machine is showing only one bar of connectivity so I’m doubtful of its speed/abilities to work with the AirCurve site (Bend, Oregon near Deschutes River Woods).
    Please tell me I’m wrong and that you are not relying on cell coverage alone. If you are I’m suggesting you address the problem sooner than latter and have software development work more hand in hand with IT (5G will take longer than most realize in smaller communities despite what the carriers are advertising).

    1. Hey Richard, I’m glad to hear that you have found a great deal of good in your AirCurve machine. Unfortunately, CPAP.com have no hand in how data is transmitted through any machine.

      The AirCurve, has several ways to access data from the machine such as, MyAir (for patients), AirView (for doctors), ResScan (for doctors), or OSCAR (for patients), that use the SD card from the machine and doesn’t rely on connectivity at all.

      We certainly, appreciate your concern and feedback on this matter. We are confident, that our manufacturers will continue to remain up-to-date with the newest technology and the influence, such technology will have on their business in the future.

      For further questions, or concerns, please feel free to reach us at: 1-800-356-5221, you can ask for Carol.

      Best Wishes!

  4. Hi I am a BiPap user, and I have anResmed AirCurve 10 VAuto. I am having a serious problem with Bacteria in my machine I think.During the summer and since I live in a warm/humid state in the South; I have turned off humidification to the machine. Now that we are in winter I once again resumed with Distilled water in the Reservoir nightly.I have been cleaning mask and tubing per the instructions – and only once a week with the water reservoir since water was not used in summer. Shortly after I began using water I began to have problems.I would awaken one or two hours with a very nasty metallic taste in my mouth. I would change the reservoir, and the mask and hose. Washing and cleaning each of these I have now found this condition to become a nightly problem.
    I cleaned all components yesterday with white vinegar/water, then repeated with Joy Lemon  dish washing soap, and dried all components in my Hurrican Drier – running all parts through two full cycles. I still get this nasty taste, only to a lessor degree. Is there a way to clean the inner parts of my Bipap machine?
    Thank you.

    1. Hi Gary, I’m sorry that you’re experiencing a bad taste in your mouth. I haven’t been able to find any information to indicate that the taste is coming from your CPAP machine, or equipment. My suggestion would be for you to speak with your doctor regarding your concern.

      Also, please see the link below to view what other users are saying about the same problem you’re experiencing.

      Enjoy your day!

  5. I started using the Air Curve 10 Vauto about a month ago. My first machine had a whining noise so I was sent another this week and found the whining is louder on this one then it was on the first one. I’m on my 4th different type full face mask because I can’t get then to seal properly. They blow air in my face and at times sounds like I’m am near the ocean during a storm. My mouth is always dry now, and I get less sleep at night then I had with the CPAP S8 I had. I’ve talked with my DR who thinks I need the highest level of air 20/25, but it was trying to blow the mask off my face, so he set the levels to 15/20 which is more tolerable but I still can’t use this machine for more than 5 hours a night. I am on level 8 on the humidifier and am getting ready to go to level 10 because of the dry mouth I am experiencing. My machine provider has been very helpful and even came out to the house to check the machine, settings, mask seal and things, but I’m beginning to think the quality of this system isn’t as good as Resmed thinks it is.
