If you are one of the 70 million Americans with a sleep disorder, you may depend on CPAP treatment. Modern machines are designed to be whisper quiet. You are supposed to be sleeping, so your CPAP treatments shouldn't disturb you. 

If you have a noisy CPAP machine, try these solutions to quiet it down. 

Check the Setup 

The easiest solution is the best place to start. Work your way through the connections looking for leaks. When air leaks out, it creates a louder-than-usual noise. 

Check the machine, mask, tubes, and humidifier. If you can make the room silent, you can trace the sound of the leak. Once you fix the connections, the sound should go away. 

The Machine Is Old 

A motor reaching the end of its useful life becomes louder. Your CPAP machine won't last a lifetime. If yours is between three and five years old, it's time to consider a replacement. 

The mechanical parts within the motor begin to wear out. This creates grinding, clicking, or whining noises. 

Water Build Up

If you have a humidifier attached to your CPAP machine, check the water tube. Condensation can build up within the tube when the air in the room is colder than the air in the tube. Those tiny water droplets moving through the tube bounce around and create a lot of noise. 

Water in the tube eventually makes its way to the mask. It then "rains" on your face while you are sleeping. If you feel water dripping on you, condensation build-up could be the source of your noise.  

Supply Replacement 

Occasional and barely there sounds could signify that it's time to replace supplies. These faint noises could be the water chamber getting a crack.

Or it could be the tube ends stretching. Finally, it could be something as simple as a chipped face mask. 

It's important to routinely replace your CPAP supplies. Doing so will help you avoid these minor pings and pops that can be annoying. 

Every Month 

You should replace the mask cushions or nasal pillow every month. These get heavy use by sitting on your face every night. While you are at it, replace the filters to keep breathing clean air. 

Every Three Months 

Once a quarter, you should replace the mask frame and CPAP tubing. This does not include the headgear. 

Every Six Months 

You should replace the headgear, chin strap, and humidifier water tube twice a year. However, if you do not keep these parts clean, you may need to replace them more often. 

Say Goodbye to Your Noisy CPAP Machine 

The approach you take to fixing your noisy CPAP machine will depend on the noises you hear. Start by looking for leaks in the connections. Then consider how old your machine is. 

Check your humidifier settings if you have one. Then set up a regular replacement schedule to prevent the parts from wearing out and getting noisy. 

Upgrade your CPAP machine and accessories to a quieter system.
