How to Look After Your CPAP Machine and Mask

If you use a CPAP machine every night, looking after your equipment is an important part of maintaining comfortable and effective therapy. Regular cleaning can help keep your equipment hygienic, while replacing worn parts can help maintain a good mask seal and airflow.

Your mask, tubing, filters and humidifier chamber are all exposed to moisture, skin oils, dust and everyday wear. Over time, these components can deteriorate and may need to be replaced.

In this guide, we'll explain how to clean your CPAP equipment, when to replace common CPAP parts and the signs that your equipment may need attention.


Why Is CPAP Maintenance Important?

Your CPAP equipment comes into contact with your face and breath every night. If you use a humidifier, moisture can also collect inside the water chamber and tubing.
Regular maintenance helps remove:
Maintaining your equipment can also help keep your mask comfortable and reduce problems caused by worn or damaged components.


How Often Should You Clean Your CPAP Equipment?

A simple cleaning routine is usually easier to maintain than occasional deep cleaning.

Always follow the cleaning instructions provided with your specific CPAP equipment.



How to Clean Your CPAP Mask

Your mask cushion sits against your skin for several hours each night, making regular cleaning particularly important.

Step 1: Disconnect the mask

Disconnect the mask from the CPAP tubing and remove any components that are designed to be removed.

Step 2: Wash with mild soap

Wash the mask and cushion with warm water and a mild, fragrance-free soap.
Avoid harsh chemicals, bleach, alcohol-based cleaners and strongly fragranced products unless specifically approved by the manufacturer.

Step 3: Rinse thoroughly

Make sure all soap residue is removed.


Step 4: Air dry

Allow the components to air dry completely before putting your mask back together.
Avoid excessive heat or direct sunlight unless specifically permitted by the manufacturer.

How Often Should You Replace Your CPAP Mask?

The complete mask does not necessarily need to be replaced as frequently as the cushion.
As a general guide, inspect your mask regularly and consider replacement when you notice:

A complete CPAP mask may commonly last around 6–12 months, although this varies depending on the manufacturer, model, usage and condition of the mask.
If your mask is still in good condition and the manufacturer allows continued use, it may not need replacing simply because a certain amount of time has passed.

When Should You Replace Your CPAP Mask Cushion?

The cushion is usually one of the first parts of a CPAP mask to show signs of wear because it sits directly against your skin every night.
As a general guide, many mask cushions may need replacement approximately every 1–3 months, depending on the mask and manufacturer's recommendations.

If cleaning no longer restores the cushion's fit and seal, it may be time for a replacement.

When Should You Replace CPAP Headgear?

Your mask headgear can stretch and lose its original elasticity over time.
Consider replacing it when:
Depending on usage and the product, headgear may commonly need replacement every 6–12 months.
Avoid overtightening your headgear. A mask that is too tight can be uncomfortable and may actually make leaks worse.

How to Clean Your CPAP Tubing

CPAP tubing can collect moisture and condensation, particularly if you use heated humidification.
To clean your tubing:
If you regularly find water inside your tubing, you may be experiencing rainout. Adjusting your humidifier settings or using heated tubing may help.

As a general guide, CPAP tubing may need replacement approximately every 3–6 months, but the manufacturer's recommendations should take priority. Replace tubing sooner if it becomes damaged or develops a leak. 

How to Look After Your CPAP Water Chamber

If your CPAP machine has a humidifier, the water chamber should be emptied regularly.
Each morning:
Many CPAP manufacturers recommend distilled or demineralised water to reduce mineral deposits and scale. Check your machine's instructions for the specific water requirements.
Never leave old water sitting in the chamber for extended periods.

As a general guide, a CPAP water chamber may commonly be replaced every 6–12 months, depending on the manufacturer and condition. Replace it sooner if it becomes damaged, develops a leak or cannot be cleaned properly.

Don't Forget Your CPAP Filter

The CPAP filter helps reduce dust and other particles entering your machine.
Filters are often overlooked, but they should be checked regularly.

Disposable filters

Disposable filters should generally be checked regularly and replaced according to the manufacturer's instructions. Replace them sooner if they become visibly dirty, discoloured or clogged.
Never wash a disposable filter unless the manufacturer specifically states that it is washable.

                             Reusable filters







 Some CPAP machines use washable or reusable filters.
If your filter is designed to be washed:
Do not put a damp filter back into your CPAP machine.

How Often Should You Replace a CPAP Filter?

Replacement intervals vary significantly between CPAP machines and filter types.
A useful general rule is to check your filter at least monthly and replace it when it becomes dirty or according to the manufacturer's recommended schedule.
If you live in a dusty environment, have pets or use your CPAP machine in an area with a lot of airborne particles, your filter may require more frequent replacement.

Signs Your CPAP Equipment May Need Replacing

Sometimes your equipment will tell you when it needs attention.
Watch out for:
1. Your mask is leaking more than usual
A worn cushion, damaged tubing or stretched headgear can contribute to leaks.
2. Your mask feels different
If your mask no longer feels comfortable or sits correctly on your face, check the cushion and headgear for wear.
3. Your equipment looks damaged
Cracks, tears, holes and damaged connections are clear reasons to replace the affected component.
4. Your tubing feels stiff
Tubing can become less flexible over time and may develop small cracks or leaks.
5. Your water chamber is cloudy or damaged
Mineral deposits, cracks and leaks can indicate that the chamber needs cleaning or replacement.
6. Your filter is visibly dirty
A dirty filter should be replaced or cleaned if it is designed to be reusable.
7. You notice persistent odours
Clean your equipment first. If an unpleasant smell remains despite appropriate cleaning, inspect the component for deterioration and consider replacement.

How to Look After Your CPAP Machine

The CPAP machine itself generally doesn't need to be washed.
Instead:
Never immerse the CPAP machine in water.

Keep Your CPAP Equipment Clean and Dry

Moisture is one of the most common issues CPAP users encounter.
After cleaning your equipment, allow the mask, tubing and water chamber to dry completely before use.
If moisture regularly collects inside the tubing, check your humidifier settings and consider whether heated tubing may be appropriate for your setup.
