You stop breathing for short periods, increasing the risk of health problems, including heart disease and stroke. Wearing a CPAP delivers continuous air to your nose and\/or mouth to keep your airways open.Here\u2019s what you should know about CPAP maintenance, along with a step-by-step guide to cleaning your CPAP machine.Why You Need to Clean a CPAP MachineFrequent cleaning of a CPAP machine is about more than just maintenance. It helps prevent bacteria, mold, and other microbes from contaminating the machine&#8217;s parts and making you sick.CPAP machines typically have these main parts:Motor or machine base \u2014 Draws air in and pressurizes it.Air filter \u2014 Purifies the air coming in from the machine.Mask \u2014 Fits over your nose, mouth, or both.Chin straps \u2014 Holds your mouth closed during CPAP treatment.Hose \u2014 Connects the mask to the machine. Pressurized air travels through the hose.Humidifier \u2014 Adds moisture to the air coming through the hose.Mold, germs, dust, and allergens can accumulate in the hose, mask, and other parts of the machine.\u00a0For instance, a dirty CPAP mask or hose may cause or worsen these or other health problems:Allergies or congestion from breathing in dust, pollen, or other allergens that collect on the mask.Asthma or lung infections from inhaling mold or bacteria growing in the hose or water reservoir. These can irritate your lungs or cause an infection.Skin infections or irritation from bacteria or oils that collect on a dirty mask.How to Clean CPAP Machine PartsYou may have seen ads for CPAP cleaning devices that use ozone gas or ultraviolet light. No experts have tested these, and they may not kill mold or bacteria.Health professionals and most CPAP manufacturers recommend following the guidelines for cleaning your machine and sticking to a regular CPAP cleaning schedule. The guidelines may include:Daily CPAP cleaningClean your CPAP mask and cushion every day, using warm, soapy water and a clean cloth, or special CPAP wipes.Weekly CPAP cleaningThe tubing or hose, humidifier tank, and filters need a thorough, deep cleaning once a week. The good news is it\u2019s easy to do with a few household supplies:A basin or tub large enough to hold the tubing and mask.Clean drinking-quality water or distilled water.A lint-free towel and a cleaning cloth.Mild, unscented soap or baby shampoo. Avoid harsh detergents or antibacterial soaps.White vinegar if you have a humidifier tank.Follow these steps to clean your machine weekly:First, disconnect it from any power source and remove any CPAP filters.Next, disconnect the air hose and tubing from the machine.If your device has a humidifier, remove the tank.Finally, separate the mask components, including the headgear, cushion, and frame.When you have separated all of the parts of your CPAP machine:Fill the tub with clean water and soap.Submerge the hose or tubing and all of the mask parts in the soapy water. Let these soak for 30 to 60 minutes, then rinse them well with clean water. Lay them on a clean towel and then let them fully air dry.If you have a humidifier tank, submerge it in a mixture of half soapy water and half vinegar to help prevent mold growth. Let it soak for 30 to 60 minutes, then rinse well with clean water and let it air dry.Clean any reusable filters weekly by submerging them in soapy water, squeezing them a few times, and then rinsing with fresh water. Let these fully air dry before putting them back into the CPAP machine.After everything dries, reassemble the parts and reconnect the hose or tubing to the machine. Put the dried reusable filter back in the machine.Common CPAP Cleaning MistakesImproper cleaning can reduce your machine\u2019s effectiveness, which, in turn, can harm your health and sleep quality. Using the wrong cleaning solutions may also damage your machine. Avoid these common CPAP cleaning mistakes:Cleaning your machine in the dishwasher or drying it with a hair dryer \u2014 The high heat from these can melt or damage parts. Always wash it by hand and let it air dry away from direct sunlight.Ignoring the filter cleaning \u2014 Dust and debris accumulate on the filter over time, which reduces the machine\u2019s effectiveness. These can also worsen allergies, asthma, or breathing problems.Not taking your machine apart before cleaning it \u2014 Leaving the hose or humidifier tank connected will prevent these items from getting a thorough cleaning.Reassembling the machine before all parts dry \u2014 This can lead to the growth of mold or bacteria.Skipping scheduled cleaning \u2014 Set aside a specific time each day to clean your mask, and the same day each week to clean the entire machine.Using harsh chemicals like bleach or ammonia, or scented soaps \u2014 These can leave behind residue, which damages the machine. Residue from harsh chemicals is also toxic to breathe in.When to Replace CPAP PartsThe mechanical part of a CPAP machine usually lasts three to five years. But other parts of the device need regular replacement. It\u2019s wise to consult your manufacturer\u2019s instructions for replacing CPAP filters, masks, and other parts, but in general:Cushions \u2014 Replace these every two weeks. They can break down and fail to form a tight seal.Filters \u2014 Replace disposable filters every two weeks and reusable filters every six months.Headgear and chin straps \u2014 These will stretch out over time, so replace them every six months.Humidifier chamber \u2014 Replace this every six months because minerals and impurities from water can build up and irritate your sinuses and airways.Mask \u2014 Replace this every three months to ensure a clean, tight fit.Tubing \u2014 This also wears over time, which affects your air quality, so replace it every three months.A CPAP machine is a vital medical device that can not only improve your sleep but also protect your overall health.
