Cleaning and Replacing CPAP Equipment

By Tracy R. Nasca - November 8, 2007

Your CPAP equipment is an important investment in your health.  Take good care of it. 

Most CPAP machines have a 2 year warranty.  If properly taken care of they can last a long time.  The outer casing of your CPAP unit should not require special maintenance.  If necessary, unplug machine, and wipe clean with a moist cloth using a mild pure soap detergent.  Dry the unit thoroughly.  Never submerge your CPAP in water.

Replace your CPAP filters when they become visibly dirty or torn.  Depending on your sleeping environment, replacement is suggested weekly-monthly.  Some homes have more dust than others, those with pets and households who have smokers will need to change filters more often.

Your mask is key to maximizing compliance, always hand clean and air dry. Daily, clean the soft cushion with a mild pure soap detergent, air dry.   Handle the delicate cushion gently to avoid tearing. Weekly, the mask frame and headgear should be hand washed in the same gentle manner.  Taking proper care, you should expect your mask to last 3-6 months before replacement is needed.  If cracking or deterioration occurs, replace promptly. If your mask was working well for you for several weeks or months, and you notice that mask leak is beginning to occur which requires you to tighten headgear to maintain a seal, this is your clue that its time to replace cushion, headgear or the whole mask system.

CPAP Tubing should be cleaned weekly and replaced annually or more often if visibly torn or dirty.  Clean with a mild pure soap detergent, rinse well, and hang to air dry. Dogs and especially cats love to play with CPAP tubing.  You may not be aware of small holes caused from claws or tiny teeth – check by turning on cpap, put on your mask and run your hand down the length of the tubing to feel for small leaks that you otherwise would not notice.  Holes in tubing CAN compromise your CPAP pressure.  Use an insulated tubing cover to protect and also to eliminate “rain out” effect from heated humidification.

Humidifiers play a role in patient comfort.  Distilled water is recommended by most manufacturers.  Do not reuse water, empty unused water each morning.  Clean water chamber with a 10 minute soak in a mild pure soap detergent, rinse well and air dry after each use.  Always fill your humidification water chamber away from your CPAP device.  Water spilled in your CPAP unit can cause damage and void warranty.

Cleaning Tips: Cut soap residue with a 1 part vinegar and 3 parts water solution if needed. Never use harsh soaps, chlorine bleach, antibacterial or alcohol based solutions. Aromatic solutions and scented oils should not be used.  Mask cleaning products are now available to make your life easier!
