CPAP machines are effective in helping people with sleep apnea achieve quality sleep. CPAP machine maintenance is essential to maximizing its benefits. It’s normal to feel hesitant when first using a CPAP machine, but with time, it becomes easier — and the benefits make it well worth the adjustment. CPAP machines come with a wide range of benefits, including curtailing the risks of developing Alzheimer’s, diabetes, high blood pressure, and of course, daytime sleepiness.

Here are four simple CPAP machine maintenance tips to keep your device clean and maximize its power in helping you reach deep, restorative REM sleep.

Clean your CPAP machine

The most crucial aspect of CPAP machine maintenance is keeping it clean. Remember, you breathe in whatever passes through the machine, so it’s essential to clean the machine and all its components at least once a week.

Here’s a step-by-step breakdown of how to clean your CPAP machine.

Step 1: Gather your cleaning supplies

You don’t need special cleaning devices or supplies for proper CPAP machine maintenance. 

To properly clean your CPAP machine, you’ll need the following: 

  • Soft cloth.
  • Warm water.
  • Mild dishwashing detergent.
  • A sink or basin.
  • Towel.

Although they can make it more convenient to clean your machine, devices such as ozone gas and UV light have not been proven to effectively kill germs. On the contrary, the FDA actually cautions against them based on reports of asthma attacks, headaches, and breathlessness from CPAP users after using them. 

Although it takes a bit more effort, sticking with everyday household items for cleaning is safe, effective, and all you really need.

Step 2: Disassemble your CPAP machine

  • Unplug your CPAP machine.
  • Detach the mask from the tubing.
  • Remove the headgear from the mask.
  • Separate tubing from any and all connectors.
  • Empty the water from the humidifier unit.

Step 3: Wipe the outside of the machine

Wipe the exterior of the CPAP machine with a damp cloth to remove dust and dirt buildup.

Step 4: Wash all components

  • Fill a sink or basin with warm, soapy water.
  • Submerge the mask, headgear, tubing, and any removable connectors in the soapy water.
  • Soak for 30 minutes, occasionally swirling the water to get the soapy water through the tubing.
  • Thoroughly clean the water chamber.
  • Wash the sponge filter if it’s reusable.
  • Hang components on a towel rack to dry or lay them on a clean towel if needed.

Never wash CPAP components in the dishwasher. The high temperature can damage components, which means you will have to replace them sooner.

Step 5: Put your CPAP machine back together

Because all parts need to be thoroughly dry before putting the machine back together, it’s a good idea to wash all the components in the morning or early afternoon. That way everything has a chance to dry before you go to bed in the evening. Once all the parts are completely dry, reassemble the CPAP machine. 

Once reassembled, turn the machine on and check for air leaks before using it again.

Replace mask cushions every three months

It’s a good idea to replace your CPAP mask cushion every three months, as they wear out over time. Moreover, masks accumulate germs and bacteria more easily the longer they are used.

Cleaning your mask daily can help it last longer. Washing your face each night before bed helps reduce facial oil buildup on the mask. If you use lotion or moisturizer, allow it to fully absorb into your skin before wearing the mask.

Know when to wash and replace filters

Different CPAP machines use different types of filters. Replace disposable filters at least once a month or more frequently if you’re using your CPAP machine in a dusty or smoky environment. You may also want to change them out more often during cold and flu season.

Wash non-disposable filters at least once a week along with the rest of your CPAP equipment. Even with regular cleaning, you should replace non-disposable sponge filters every three months.

Replace the water every day

If mold or mildew develops in your machine, removing it is nearly impossible, and it often requires full machine and accessory replacement. To prevent buildup, replace the water in the humidifier compartment daily.

Always use distilled water in the humidifier compartment. Minerals in tap or even filtered water can accumulate over time, potentially damaging the CPAP machine’s motor. 

Get a good night’s sleep with regular CPAP machine maintenance

Don’t let poor CPAP machine maintenance compromise your health or worsen conditions. Regular cleaning helps prevent illness and ensures optimal performance. With regular CPAP machine maintenance, you can safeguard your machine from germs and mildew and enjoy restorative sleep each and every night.
