Quiet CPAP Machines for Quiet CPAP Therapy

What steps can you take to make your CPAP experience quieter? What are some of the quietest machines available today? How loud is a CPAP machine? Find answers to these questions and more in this article!


Using a CPAP machine is supposed to improve your quality of sleep, but some users find that the noise of their machine makes it difficult to sleep. If you’re looking for a quiet CPAP machine, you’re probably digging through reviews to find out what other users are saying.

The only problem – everyone perceives sound differently. This means that even when machines are advertised as being “quiet,” user reviews on quietness can vary, leaving you confused. When you’re trying to find the quietest CPAP machine for quiet therapy and a good night of rest, here are a few tips and ideas to keep in mind.



How Loud is a CPAP Machine?

Every CPAP machine comes with a decibel (dB) rating that’s specified by the manufacturer. Most CPAP machines are rated at about 30dB, which is equivalent to the sound of raindrops. For comparison, 20dB is like a whisper or softly rustling leaves, while 40dB is like the sound of your refrigerator humming. Of course, your perception of sound, as well as the conditions of your sleeping area, can make it tough to gauge.

When users switch to a new machine, it often sounds a lot louder at first when it’s really not. Every CPAP machine has its own sonic quality, so even though machines may have the same decibel rating, they still will sound a bit different. Sometimes it just takes a bit of time to get accustomed to the new sound.



5 Tips for Creating a Quiet CPAP Environment

So many different things can influence how loud your CPAP machine seems to you. Several different factors affect the sound of your machine, so there are several things you can do to create a quiet CPAP environment.

1. Change the Filter Regularly to Keep Your Machine Quieter

It’s so important to change your filter regularly to reduce the noise level and improve the performance of your CPAP machine. If your machine seems to get louder, it may need a filter change. Not only will filter changes reduce the noise level so you can sleep more soundly at night but a filter also keeps the dust and dirt out of your machine motor will prolong the life of your machine, too.

2. Keep Your CPAP Machine Away from Your Ears

In many cases, having your CPAP machine below ear level can reduce the noise. You don’t have to keep it on your nightstand next to your head. Keep it below your bed and it may reduce the noise and vibration. You can also go with a longer hose so your machine can be placed further away from your bed. Just remember that a longer hose increases the chance of rainout if you use a humidifier with your machine.

3. Consider a CPAP Machine with an Integrated Humidifier

Machines used with optional humidifiers often are reviewed as noisier, and some users decide to go with standalone humidifiers that can be placed further away from the machine. A quieter choice can be a machine that has an integrated humidifier since the sound is condensed a bit when the humidifier is attached.

4. Pair Your CPAP Machine with a Quiet Mask

You may be surprised to learn that a lot of the noise you hear at night as air traveling through the hose and into your mask. Your machine might be very quiet, but your mask could be noisy. Inform yourself on the best quiet CPAP masks for quieter CPAP therapy. You can also purchase masks that come with free returns so you can send them back if you’re not happy with the noise level.

5. Reduce Vibration and Sound by Placing Your Machine on a Soft Surface

Sometimes your breathing pattern or pressure settings may result in a louder machine. Lowering the intensity of the machine’s vibration by placing it on a towel or foam pad can reduce the noise.

    After Recent dream station purchase. Dr recommended no humidifier use.
    Noise from mask very loud without water chamber. Not the mask (Used several different masks and hearing every inspiration)
    . Provider nor manufacturer able to help.
    Any suggestions

    • I also use a DreamStation Auto (not the DreamStation Go) at home, and I experience some of the same noise. Unfortunately, there’s no way to eliminate the noise from your CPAP completely. In fact, you have one of the quietest machines on the market, so I’m not sure there’s a better option than what you currently have. Over the 2 years I’ve been in CPAP therapy, I’ve gotten used to the noise, and now can sleep whether I hear it or not. Adjusting to a new CPAP machine is never going to be easy, but when you finally do, the level of relief you’ll feel having your sleep apnea treated will be worth it.
