In this article, we are going to focus on four important topics on Cpap machines.

CPAP machines are designed to improve the quality of your sleep. Unfortunately, a noisy machine can affect the quality of your sleep and make it possible for you and your partner to get a good night’s sleep.

Humans perceive sound differently. Therefore what could be noisy for you could be quiet for another person.

If you’re on the hunt for the quietest CPAP machine, there are essential factors that you should consider. If you adhere to these tips, you’ll be able to get a silent machine and learn how to quiet a noisy one.

Are Cpap Machines Loud?

All CPAP machines have sound decibel (dB) ratings recorded by the manufacturer. Most of these CPAP machines have a sound rating of 30 decibels and are considered as loud as the sound of raindrops.

To get a better understanding:

  • Snoring sound ranges typically between 60-90 decibels
  • Humming fridge generates about 40Db
  • Whisper or rustling leaves produce about 40 decibels
  • Vacuum cleaners (70 decibels)
  • Chainsaws (100 decibels)

They aren’t that noisy. In some cases, snoring can be as loud as laundry and other household chores.

But because the person’s perception of sound is always different, it can be almost impossible for your gauge.

In most cases, after switching to a new machine, it’ll feel louder than the previous one.

In addition, every machine has different sonic quality even at equal decibel rating.

Cpap Machine Making High Pitched Noise

Two machines with equal decibel ratings (say 28 decibels) can have different sound pitch also known as sonic quality.

The difference in sonic quality can make different people perceive the sound it generates differently.

A perfect example is the Transcend and DreamStation Go.

The Transcend is rated 26 dB, and DreamStation Go is 30 decibels.

While Transcend may seem like the best deal, you’ll be surprised to learn that most people don’t like the high pitched sound Transcend makes.

DreamStation has a sound decibel rating of 30 dB, but most people are comfortable with it because it doesn’t produce high pitched sounds.

However, you should know that it’ll take time before you get used to the sound of your new CPAP machine/

In addition, a little background noise doesn’t have to be bad for you. Some people will do fine with some background noise while others can’t fall asleep with even the slightest sound.

How to Make a Cpap Machine Quieter

Some factors can affect how quiet or loud your device is. Below are some quick fixes you can implement to make your machine quieter.

Filter Maintenance

It’s always advised to replace the filter frequently. This will help reduce noise levels and also improve its performance.

Replacing the filter regularly will also keep dust and dirt out of your motor hence prolonging its lifespan.

Integrated Humidifier

According to different reviews, we collected online, CPAP machines with optional humidifiers are noisier than ones with an integrated humidifier.

For this reason, most users have resorted to using CPAP machines that have standalone humidifiers that can be stored far away from the machine itself. (Read my guide on quiet humidifiers)

But a quieter option is investing in a CPAP with an integrated humidifier.

CPAP Muffler

Just like a car requires a muffler, and a generator requires a silencer, it also needs a muffler.

The recommended option is the Q-Tube Inline muffler that will help reduce unwanted noise by dampening sound generated by air as it travels from the hose to the mask.

Quiet Mask

You will be shocked to learn that most of the noise you hear at night is a result of air through the hose to the mask.

Your CPAP mask could be the cause of unwanted noise. If that’s the case, opt for a quiet mask to help you reduce noise.

On Making a CPAP Machine Quieter

Although every person has a different perception of sound, it’s possible to find a quiet CPAP machine or quiet your noisy machine

I just got a philips dreamwear nasal pillow. The noise created by the slot on the gel pillow is the problem. Put a 8mm or 1/4 machine screw about 1/2 in. long made either nylon (license plate screw) or stainless so it does not get rusty.

For my S9 I used an oversized plastic box from Walmart and lined it with cotton blankets which hopefully will minimize any off-gassing from the box's plastic.
