Maintaining the pump

The CPAP pump should be cleaned every day to prevent a build-up of dust and dirt. A clean, slightly damp cloth or an all-purpose surface wipe can be used. It is best to avoid chemicals such as bleach or ammonia.

Maintaining the filter

A CPAP pump has removable filter that traps particulates from the air

There is a small hole at the back of the pump where room air is sucked in through a small filter. The filter is made of spongy material that stops dust being pulled into the machine.

This should be dusted, vacuumed or cleaned with warm water and a mild detergent, depending on your CPAP model, on a monthly basis. Remember to thoroughly air-dry your filter before reuse.

Filters usually last between six months and a year but may need replacing more regularly. It is best to replace the filter before it becomes too clogged with dust.

Maintaining the mask

If there is a build-up of skin oil on the mask you may encounter problems:

  • Your mask may slip out of position, causing air to leak from the sides
  • You could get an infection
  • Your skin may become sore or break out in spots.

To prevent these problems your mask cushion needs to be washed daily with warm water and a mild detergent, then rinsed and left to dry away from direct sunlight. It is best to use a detergent that does not contain oil or fragrance.

Your headgear can be cleaned weekly in the washing machine at 30 degrees Celsius. The plastic frame can be washed weekly with warm water and a mild detergent.

Masks usually last between six and 12 months. Certain parts, such as the mask cushion, may need replacing more regularly.

Facial care

It is advisable to wash your face before putting your mask on to prevent the build-up of facial oil. It is also better not to wear face creams, moisturisers or any skin products underneath the mask.

If you have very sensitive skin, you can wear a mask liner between your face and the mask. This is a piece of cloth that can help to prevent the mask from rubbing against sensitive skin and is often used alongside an appropriate face cream.
