Best CPAP and BiPAP Machines (2026): Tested and Ranked
Last updated August 2026
If you want the best all-round CPAP machine, the ResMed AirSense 11 AutoSet is our top pick for quiet auto-adjusting pressure, a strong app, and integrated humidification. The Philips DreamStation 2 Auto CPAP is the runner-up. The one thing that matters most: a CPAP or BiPAP machine and its pressure setting require a prescription — see the medical note below before you buy.
An honest medical and prescription note
CPAP and BiPAP machines are FDA-regulated medical devices. In the US you legally need a valid prescription to buy the machine and masks, and your pressure setting must be determined by a sleep study and a clinician — not guessed at home. This page is buying guidance, not medical advice. If you snore heavily, gasp at night, or feel exhausted despite sleeping, talk to a doctor about a sleep study first. Never adjust prescribed pressures, self-diagnose sleep apnea, or stop treatment without your clinician. Replacement accessories like hoses, filters, and cleaning kits generally do not require a prescription; the machines and masks do.

How to choose a CPAP or BiPAP machine
Once you have a prescription, the choices come down to machine type, pressure mode, and comfort features.
CPAP vs. APAP vs. BiPAP. These are different therapies, and your prescription specifies which you need.
| Type | How pressure works | Typically prescribed for |
|---|---|---|
| CPAP | One fixed pressure all night | Standard obstructive sleep apnea |
| APAP (Auto CPAP) | Auto-adjusts within a range | Variable needs, position/stage changes |
| BiPAP | Separate inhale/exhale pressures | Higher pressures, exhale difficulty, certain conditions |
Machines like the AirSense 11 AutoSet and DreamStation 2 Auto are APAP units that also run in fixed-CPAP mode, so they cover the most common prescriptions.
Comfort features that improve adherence. The best machine is the one you will actually wear:
- Heated humidifier and heated tubing reduce dryness and “rainout” — the Fisher & Paykel SleepStyle builds humidification in.
- Expiratory pressure relief (EPR/Flex) eases the push-back when you exhale.
- Ramp starts low and rises as you fall asleep.
- Quiet operation — modern units run around 26-30 dB.
- App and data tracking so you and your clinician can see usage and events.
The mask matters as much as the machine
Comfort and therapy success live and die by mask fit. Nasal masks and nasal pillows (like the CPAP Nasal Mask with Headgear) suit people who breathe through their nose and want minimal contact. Full-face masks (the Full Face CPAP Mask Kit) suit mouth breathers and higher pressures. Keep spare headgear straps, a good 6ft hose, and a cleaning kit on hand — they are the parts that wear out first.
Common mistakes
- Buying a machine without a prescription or a fitted pressure. The wrong pressure makes therapy ineffective or uncomfortable.
- Neglecting mask fit. Leaks and pressure sores are the top reasons people quit CPAP. Fit and re-fit until it seals gently.
- Skipping humidification in dry climates or winter, then blaming the machine for a sore throat and dry nose.
- Poor cleaning. Hoses, masks, and water chambers need regular washing; dirty equipment risks infection and shortens part life.
- Not replacing consumables. Filters, cushions, and tubing degrade on a schedule — old parts leak and lose performance.
FAQ
Do I need a prescription to buy a CPAP machine? Yes. In the US, CPAP and BiPAP machines and masks are prescription medical devices, and your pressure setting must come from a clinician based on a sleep study. Accessories such as hoses, filters, and cleaning kits usually do not require a prescription.
What is the difference between CPAP and BiPAP? CPAP delivers one steady pressure throughout the night. BiPAP delivers two pressures — higher when you inhale and lower when you exhale — which helps people who need high pressures or struggle to breathe out against CPAP. Your doctor prescribes the one that fits your condition.
How do I choose the right CPAP mask? Match the mask to how you breathe and your pressure. Nasal masks and nasal pillows suit nose breathers who want a lighter feel; full-face masks suit mouth breathers and higher pressures. A gentle, leak-free seal matters more than the style — expect to try a couple before one feels right.
How often should I clean and replace CPAP parts? Wash the mask, hose, and water chamber regularly (rinse frequently, deeper clean weekly) with mild soap and water. Replace cushions and filters on the manufacturer’s schedule — often monthly for cushions and filters, and the hose and mask every few months. A cleaning kit makes this routine easier.
Can APAP machines work as a fixed CPAP? Yes. Most auto-adjusting (APAP) machines, including the models here, can also run in fixed-CPAP mode. That flexibility is why they suit the widest range of prescriptions — your clinician sets the mode and pressure range.

Bottom line
Start therapy with a prescription and a fitted pressure, then choose the machine that keeps you compliant. The ResMed AirSense 11 AutoSet is our overall pick for quiet, auto-adjusting comfort; the Philips DreamStation 2 and humidifier-focused Fisher & Paykel SleepStyle are strong alternatives. Invest as much attention in your mask and consumables as in the machine. For setup, mask fit, and maintenance, read our CPAP buying guide or compare every model in our reviews.
