CPAP Care, CleaniNG and Replacement

Before Sleep:
  1. Clean area of face where mask will be placed to remove facial oils and improve mask fit. Use a pH neutral cleanser and avoid use of lotions and creams on this area.
  2. Lie down in bed and turn on power to CPAP system.
  3. Apply the mask, ensuring proper placement of headgear (straps) around the head. Fasten strap(s) to the mask frame ensuring straps are not twisted. Check mask placement to ensure it is centred on your face.
  4. Check for air leaks around the mask seal by feeling around the area. Note: Every mask has an exhalation port (usually a series of small holes) on the front where air can be heard and felt - this is a normal leak.
  5. If an air leak is felt around the mask, gently pull the mask away from the face while the air flow is on and reposition on the face to reduce the leak.
  6. If bothersome leaks persist after repositioning, gently tighten headgear straps equally on both sides.

Note: Over tightening headgear straps can worsen air leaks and lead to skin irritation.

In the morning:
  1. Remove your mask by un-clipping strap from the mask frame. Note: Removing the mask while straps are fastened will stretch headgear leading to more frequent replacement.
  2. Turn the system’s power off.
  3. Remove the humidifier chamber from the system and dispose the remaining water.
  4. Wipe the silicone cushion seal of mask with a damp cloth.

Note: Never move the CPAP system when the humidifier is attached and contains water.  Doing so may result in water damage to motor.


CPAP Cleaning

When cleaning your CPAP equipment use mild detergents that do not contain ammonia, bleach or antibacterial properties.

An alternative to soap is a solution one part vinegar to seven parts water. Remember, you will be inhaling whatever does not get rinsed off, so do not use chemicals or household cleaning agents and always rinse well. Allow everything to air dry before reassembling.

  • Fine Particle Filters (white disposable filters). Replace every two weeks.
  • Change the filter if it becomes grey or brown in colour (usually every two months). Environmental factors in your home will require the filter to be replaced more frequently (pets, cigarette smoke, excessive dust).
Humidifier Chamber
  • Daily – Empty the chamber to avoid bacteria growth. Use only distilled water in the humidifier.
  • Weekly – Wash once a week with warm soapy water, rinse well and place upside down.
  • Yearly – Replace humidifier chamber.
  • Weekly – Use a slightly damp cloth to wipe the CPAP unit. Unplug the machine before cleanings.
  • Daily – Wipe down the mask seal and forehead pads with a slightly damp cloth.
  • Weekly – Disassemble the mask and wash in warm soapy water. Rinse well. Leave parts to air dry before reassembling.
  • Every 6-12 months – Replace mask.
  • Weekly – Run warm water with a drop of soap through the tubing. Rinse well. Shake out excess water and hang the tubing in the shower to drip dry.
  • Yearly – Replace tubing.
