Our Review

The 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

One of our top picks for the best fixed-pressure CPAP machines is the Luna G3 CPAP Machine With Heated Humidifier. Brand new to the market from 3B Medical, a manufacturer committed to performance and innovation, this device combines comfort and convenience and is ideal for newly-diagnosed patients and veteran users alike.

Not only is the Luna G3 CPAP outfitted with a humidifier, which helps prevent dry mouth and sinus-style headaches, but it also has a preheat feature that lets you warm the humidifier before you crawl into bed for added comfort. Plus, the included AutoHumidity control lets you maximize your moisture settings without causing rainout.

Since the modem is built into the device, the Luna G3 CPAP takes up less space on your nightstand, too—but just because it’s small doesn’t mean any features were sacrificed.

From the user-friendly screen display, you can easily access sleep reports, view the time and temperature, and receive helpful replacement reminders for CPAP supplies like tubing and air filters. Additionally, you can use your Wi-Fi to store and send your sleep data to your healthcare provider, allowing them to stay up-to-date on your progress, needs, and goals. This feature can even potentially cut down on doctor visits and co-pays since your provider can view your sleep reports digitally. 

Good For:

  • Light Sleepers
  • If You Are New to Sleep Apnea Therapy
  • Those Who Prefer Heated Humidification

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

Lifestyle NeedsUltra-Quiet, Built-In Humidification
Size10.78″ L x 6.24″ W x 3.34″ H

Our Review

The DreamStation 2 from Philips Respironics is an excellent option for those who are recently diagnosed with sleep apnea and newly acclimating to sleep therapy equipment. Designed with your comfort in mind, this machine has simplified the user experience without compromising top-tier features. Plus, it’s 29% smaller than former models so it takes up less space on your bedside table.

Enjoy the comforts of moistened, pressurized air without adding bulk to your nightstand or your suitcase, thanks to the integrated humidifier. With five heat settings to choose from, you can make personalized adjustments to your humidification to prevent dry mouth and nasal soreness—which is especially helpful if you live in or frequently travel to a temperate region.

Additionally, this machine is equipped with a Ramp Plus feature that lets you ease into your sleep therapy at a lower pressure setting as you drift to sleep. The DreamStation 2 will make automatic adjustments after 30 minutes to meet your pressure needs so you can sleep soundly knowing the machine will instinctively make adjustments on your behalf.

Other popular features of this device include its intuitive color touchscreen that lets you easily navigate the menu to modify your sleep therapy settings as well as its sleep data tracking system via the DreamMapper app, which allows you to view information about your previous night’s sleep.

Overall, the DreamStation 2 boasts tech-savvy settings that boost user efficiency, increase your comfort, and keep you informed on your sleep apnea treatment so you can sleep well and stay well.

Good For:

  • Those Who Are New to CPAP
  • Those Who Want an At-Home and Travel Machine All in One
  • Those Who Like to Track Sleep Data
  • Light Sleepers

Human Design Medical Z2 Auto Travel CPAP Machine

HDM Z2 Auto Travel CPAP Machine
PriceAround $529
ManufacturerHuman Design Medical
Lifestyle NeedsUltra-Portable and Quiet
Size10″ in L x 8.5″ in W x 4.5″ in H

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
