CPAP mask cleaning

You made a smart and important decision involving your health the day that you decided to move forward and initiate PAP therapy for your sleep apnea. You have invested time and money when purchasing and acclimating to this device and supplies. Why not get the most out of that investment?

Without proper cleaning and maintenance, your PAP machine and supplies can grow harmful bacteria, and with COVID-19 amongst us it is important to be as healthy as we can be. Daily cleaning of your supplies is important to maintaining the longevity of your investment, but also to help keep your airway open while you sleep by maintaining a proper seal between your face and the mask. If your cushion losses the proper seal, airflow will start to push out the sides, and you no longer have a proper seal to maintain your open airway. This could lead to you stopping breathing, and defeat of the purpose of using the mask and device.

A vital part of maintaining the integrity of your seal is by cleaning it daily. You should wash the cushion in warm, soapy water using a mild dishwashing detergent (such as Purdoux soap) and allow to air dry, you can also use a PAP mask wipe (Purdoux PAP wipe) that is quick and convenient, you can find these in our online store. The soap, and/or PAP wipes acts as a grease cutter to wash away oils from your skin left on the mask. This can go a long way to extend the lifetime of your cushion and ensure an adequate mask seal.

Routine cleaning and replacement of your PAP supplies will keep you healthy in a time like this. You should replace the distilled water in your heated humidifier chamber daily. Do not allow this water to sit for extended periods of time, as bacteria love a warm, wet place to grow. If you are ill, daily cleaning of all your supplies is a good practice until your symptoms are gone.

Here is a guide to helping you understand the cleaning and maintenance of your PAP equipment.


  • Wipe mask interface with Purdox PAP wipes or wash with mild dish soap (such as Purdoux soap)

Weekly Cleaning

  • Water Chamber:
    • Fill sink with warm water and mil soap and submerge chamber for 15 minutes.
    • Rinse and allow to air dry


  • Hose:
    • Disconnect tubing from PAP machine
    • Gently wash in solution of warm water and mild soap
    • Submerge hose for 15 minutes; do not submerge electric connector
    • Rinse hose and hang to dry (on towel rack or shower rod)


  • Mask:
    • Submerge mask completely in warm soapy water for 15 minutes
    • Keep Velcro straps attached to headgear when cleaning, this will help the Velcro stay “sticky”
    • Rinse mask and allow to air dry


  • Filters:
    • Respironics: Rinse the filter with the dark blue frame with warm water only and let air dry completely
    • ResMed: Flick the dust from the filter once a week

It’s time to replace your mask, cushion, headgear and other supplies when you can no longer maintain a good seal despite regular cleaning and proper mask fit and placement. Regular replacement of all of your disposable supplies is an important part of keeping you healthy and the equipment working properly.
