If you want “silent nights,” you should look for machines that make less than 30 dB of noise, which is about the same as the sound of leaves rustling.

“The ResMed AirSense 11 and ResMed AirSense 10 are the quietest models on RespBuy, followed by the BMC G3 A20, which is also very quiet. Even though they are usually a little louder than full-size home machines, travel units like the ResMed AirMini and BMC M1 Mini are still very quiet.” – Rakesh Chavan, New Delhi

The Quiet Leaders (for full-size and home use)

1) ResMed AirSense 11 AutoSet—whisper-quiet at about 27 dB

The newest flagship from ResMed is always around 27 dB, which makes it one of the quietest machines you can buy right now. That’s quieter than most sounds in the house, which is great if your partner is a light sleeper.You can buy the AirSense 11 AutoSet 4G at RespBuy.

Best for: People who want the quietest experience and modern comforts like a touchscreen, the myAir app, and smart pressure response.

2) ResMed AirSense 10 AutoSet — ~27 dB class that has been tested

The AirSense 10 from the last generation is still a quiet classic. Standard ResMed PAPs are rated at about 27 dB. This is a great choice if you want the best quiet without having to buy the newest model.You can buy the AirSense 10 AutoSet Tripack at RespBuy.

Best for: People who want to save money but still want “library-quiet” operation and ResMed reliability.

3) BMC G3 A20 — ≤28 dB with noise reduction that works in stages

The BMC G3 A20 says it can be as quiet as 28 dB thanks to its multi-stage noise reduction. This puts it right behind the ResMed duo and still firmly in the whisper-quiet range.You can buy the BMC G3 A20 Auto CPAP at RespBuy.

Best for: People who want quiet therapy with strong comfort features (like pre-heat and heated tubing options) at a good price.

A quick note about Philips: The official specs for the DreamStation 2 say it has about 27 dB, but you should check to see if it’s still available and what the situation is before you buy it. RespBuy’s live catalogue has DreamStation Auto and DreamStation Go. If you’re only looking at noise levels, ResMed A11/A10 and BMC G3 already meet the “quietest” brief.

The Quietest Ways to Travel (Portable/On-the-Go)

Travel machines are smaller and a little louder than full-size machines, but they are still made to be used in hotel rooms and on planes without bothering other people.

4) ResMed AirMini: about 30 dB and fits in your pocket.

The AirMini makes about 30 dB of noise, which is still “whisper-quiet,” but it’s a little louder than the A10/A11 because it has a small turbine. There are good reasons why this is the most popular travel CPAP in the world.You can buy the AirMini Travel Auto CPAP at RespBuy.

Best for: People who travel by plane or train a lot; works with HumidX (waterless) and myAir app.

5) BMC M1 Mini: a small APAP that makes less than 30 dB of noise

The BMC travel APAP is very light and has a sound level of less than 30 dB, which is similar to the AirMini. This is the best quiet travel option that isn’t ResMed. You can get the BMC M1 Mini Travel Auto CPAP at RespBuy.

How to Pick Your “Quiet” CPAP (Tips for India)

• If you want complete silence at home, choose the ResMed AirSense 11 first, or the AirSense 10 for value; both are around 27 dB. The BMC G3 A20 (≤28 dB) is a strong option that is quieter than most.
• If you travel a lot, the AirMini or BMC M1 Mini will keep you around 30 dB in a small space. This is great for flights and Indian train rides where space and outlets are limited.
• Power cuts and voltage: Think about getting a CPAP power bank or DC adapter. These are useful during the hot summers and monsoons in India when outages are common. RespBuy shows you backup options.
• Masks are important: A mask that doesn’t fit well makes more noise than the machine itself. A ResMed AirFit/AirTouch or compatible BMC mask that fits well cuts down on hissing and “whoosh” sounds a lot. (Also, make sure the tubing fits tightly in the humidifier port.)

A quick list of things to do to make noise go away (works for any machine)

1. To stop small leaks, put the hose and water chamber back in place.
2. Place the machine so that its back vents aren’t against a wall.
3. Use a hose cover to reduce vibration.
4. Check the filters every month to make sure they are clean. Clogged filters make fans work harder (and louder).
5. Humidifier settings: If they’re too high, the gurgle will get worse. Set them low for India’s humid nights.
