CPAP Cleaning Tips

     Simple Steps to Clean CPAP Machine

1. Disassemble the parts of the CPAP machine. Unplug your CPAP machine from its power source, as there may be a danger of electrical shock if you do not. Disconnect your mask from the CPAP tubing. If your mask has a headgear, remove or detach it. If there are other pieces that are easily reattached, these also can be separated. Remove the CPAP tubing from any connectors, the humidifier output, or from the CPAP machine itself, if it connects directly. If you have one, remove the water chamber from the humidifier unit of the CPAP machine, and separate it into its pieces if these are present (and if this is easily done). Most modern water chambers open but may not separate into different parts.

1. Take a soft cloth and wet it with warm water. Gently wipe down the external surface of the CPAP machine to remove dust. (Again, make certain it is unplugged while cleaning.)
2. Fill a small sink, tub, or basin with warm water. Add a small amount of gentle dish soap. Some will even use a little vinegar in the water (diluted to a ratio of 1:1 with water), but this is optional. Submerge the mask, headgear, tubing, and any connectors in the warm soapy water. Allow it to soak for a short period of time (about 30 minutes). Alternatively, wipe out the mask with a soft cloth and warm water, and swish soapy water through the tubing. Allow everything to air dry on a towel or by hanging (such as over the shower curtain rod in the bathroom). These items should ideally be cleaned every day, but make an effort to do it at least weekly. The humidifier's water chamber should be cleaned with hot water and mild soap. It should also be allowed to air dry.

      Note: Remember to only put distilled water in the humidifier. If you don't, there's an increased risk of                        illness as well as the probability that hard minerals will build up on your equipment.

          The humidifier should ideally be cleaned weekly.

4. Some CPAP machines have filters in place. It will be important to review your manufacturer’s instructions or ask your equipment provider about how these should be maintained. Some can be rinsed but others must be replaced, and the timing of this will vary depending on the environment you use the machine in. The replacement of disposable filters should generally be done at least monthly and perhaps as frequently as every 2 weeks.

5. Finally, after everything has been allowed to air dry, reassemble the various parts. Apply the headgear to your mask, hook the mask back onto the tubing and any connectors, and connect the tubing back to the humidifier or directly to the CPAP machine. Turn the machine on briefly and listen for any air leaks that weren’t there previously. 

If you find that your sleep apnea symptoms ​have returned or you feel like your machine isn’t working right, bring it in to your equipment provider or sleep specialist and have things checked out.

The risks associated with CPAP therapy are minimal, but keeping your equipment clean with these instructions may help to ensure your long-term health and benefit from the therapy. Don't waste your money on a highly advertised cleaner or sanitizer that adds little to the safety or cleanliness of CPAP use.
