How to properly clean CPAP equipment

Sleep apnea support Nov, 02 2023

Use our cleaning checklist to prolong the lifespan of your device

Now you have decided to treat your sleep apnea with CPAP* therapy, it is important you further safeguard your health - and the life of your equipment - by regularly and thoroughly cleaning your mask, seal, tubing, and device.

Sweat, oil, and dead skin cells can accumulate on your mask and tubing, so it is important to clean them daily to reduce dirt, allergen, or pathogen build-up. It is advisable to clean your mask headgear weekly.

Water in the CPAP machine and water chamber can also become a breeding ground for bacteria and germs, so they should be cleaned at least once a fortnight to avoid the risk of infection and disease as well as to prevent odours.

Read on for our cleaning suggestions but remember to refer to the user instructions that came with your CPAP equipment for more specific guidelines.
