Caring for your equipment


    Maintaining and caring for your equipment is essential so that you can get the most out of your therapy.

    Mask care


    You may not realise it, but over time your skin releases facial oils that can reduce the quality and performance of your seal and mask. So after wearing your mask, clean it thoroughly to remove any facial oils.

    Clean the cushion of your mask every morning, after using it at night. That way, you will have a clean, dry mask ready to use for your next night. Cleaning your mask will also remove facial oils to optimise your mask's seal.

    To clean your mask, hand wash it each day with mild soap. Avoid harsh cleaning products, which may damage the mask, or leave harmful residue. Allow to dry away from direct sunlight.

    For more information on how to clean and care for your mask, please refer to your mask user guide.

    Device care

    To be able to deliver consistent, quality therapy, your device needs to be well maintained. A blocked air filter may impact on the pressure delivered to you. It's important to examine the air filter for holes or dust build-up on a monthly basis. Refer to your user guide for specific recommendations on how often you should maintain your device.

    Humidifier care

    Maintaining your humidifier is important in order to achieve optimal therapy and prevent the build-up of deposits.

    After each use, we recommend that the water tub should be washed out with a mild detergent and warm water. Then it should be thoroughly rinsed and dried, away from direct sunlight. The tub should also be checked once a month for wear and deterioration. If any component has cracked or become cloudy or pitted, the tub should be replaced.

    Please note that this cleaning information is only a summary. For more detailed information, please refer to your product user guide.


    It's important to replace your mask regularly to ensure that you maintain comfortable, reliable therapy every night.

    Some indications that it might be time to replace your mask (or parts of it) are if you:

    • have to tighten the straps very often
    • notice the mask has lost its spring
    • feel your therapy may be less effective than usual
    • find that the cushion is still slippery, even after cleaning it
