Cleaning your CPAP machine should be a regular part of your CPAP routine. Most machines will have a humidifier, tube and filter that require some level of maintenance. By cleaning and maintaining your CPAP equipment you can improve the lifespan and quality of your machine.

Cleaning Your Humidifier Tub

How Often: Every week


  • When cleaning your humidifier tub we recommend you fill it with white vinegar and let it soak for a few minutes. This will help remove any build up or stains from your tub.
  • After this, the humidifier can be washed in warm, soapy water and rinsed under fresh, running water. Specific soap for CPAP equipment can be found here.
  • Allow the humidifier to air dry.

Detachable humidifier tubs (such as that in the ResMed AirSense 10) may be able to go in the dishwasher.

CPAP Tubing


How Often: Every week


  • Remove the tubing from your CPAP machine. Wash it in warm, soapy water. You can use a tube brush to help clean if you wish. CPAP tubing brushes can be found here.
  • Rinse the inside and outside of the tube under running water.
  • Hang the tubing up to air dry.

When cleaning your tubing it is a good idea to go over it and check it’s integrity. For advice on how to check your CPAP tubing, Click here.



How Often: Most filters need to be replaced every 3-6 months.

It is advisable to take it out and give it a flick weekly as well.

Your CPAP machine will likely have a removable air filter. These filters prevent dust from entering your machines motor. Be sure to check your product manual for specific advice on your CPAP machine’s filter.
