Keeping your CPAP equipment clean is essential for effective sleep apnoea therapy. Daily use naturally leads to the buildup of moisture, skin oils and airborne particles. Without proper cleaning, this can affect mask sealing, airflow quality and overall comfort.
The good news is that CPAP maintenance is simple once you follow a regular routine.
Why CPAP Cleaning Is Important
Routine cleaning helps to:
• Maintain proper airflow performance
• Reduce bacteria and odour buildup
• Prevent mask leaks caused by skin oils
• Extend the lifespan of equipment
• Improve comfort during therapy
Clean equipment also helps prevent irritation of the skin and airways.
Daily CPAP Cleaning Routine
A quick daily clean makes the biggest difference.
Each morning:
• Disconnect the mask cushion from tubing
• Wash the mask cushion using warm water and mild soap
• Rinse thoroughly to remove residue
• Allow to air dry away from direct sunlight
Avoid using strong detergents, alcohol or bleach.
Weekly CPAP Cleaning Routine
Once per week, perform a deeper clean.
Clean the following components:
• CPAP mask frame and headgear
• Tubing or heated hose
• Humidifier water chamber
Steps:
• Soak parts in warm soapy water for 10 to 15 minutes
• Gently clean with hands only
• Rinse thoroughly
• Hang tubing to dry completely
Ensure all components are fully dry before reconnecting.
Cleaning the CPAP Machine Exterior
The machine itself should never be submerged in water.
Instead:
• Wipe the exterior using a slightly damp cloth
• Keep air intake areas dust free
• Ensure filters are clean and properly installed
Always unplug the device before cleaning.
CPAP Filter Maintenance
Filters protect both you and the machine.
Check filters regularly:
• Disposable filters should be replaced every 1 to 2 months
• Reusable filters should be rinsed weekly and fully dried
• Replace sooner if exposed to dust or pets
Blocked filters reduce airflow efficiency.
Humidifier Care
Humidifiers improve comfort but require attention.
Best practice:
• Empty remaining water each morning
• Use distilled or purified water where possible
• Dry the chamber daily
• Clean weekly to prevent mineral buildup
Never leave stagnant water inside the chamber.
Replacement Schedule for CPAP Parts
Cleaning alone cannot prevent normal wear.
Typical replacement intervals:
• Mask cushions: every 1 to 3 months
• Filters: every 1 to 2 months
• Tubing: every 6 to 12 months
• Headgear: every 6 months
• Water chamber: every 6 to 12 months
Replacing worn parts helps maintain a reliable seal and consistent therapy.
Should You Use CPAP Cleaners or Sanitisers?
CPAP cleaning devices and wipes can help simplify maintenance, especially for frequent travellers or busy users. However, they should complement regular washing rather than replace it.
Always follow manufacturer recommendations for compatibility.
Common Cleaning Mistakes to Avoid
Avoid these frequent errors:
• Using harsh chemicals or antibacterial sprays
• Reassembling equipment while still wet
• Skipping weekly deep cleaning
• Ignoring filter replacement
• Washing headgear too aggressively, which reduces elasticity
Simple habits prevent most equipment problems.
Travel Cleaning Tips
When travelling:
• Carry CPAP wipes for quick cleaning
• Allow equipment to dry before packing
• Store machine in a protective travel bag
• Keep spare filters available
Maintaining hygiene while travelling ensures uninterrupted therapy.
Final Thoughts
Regular CPAP cleaning and maintenance protect both your health and your equipment investment. A few minutes of daily care improves comfort, reduces leaks and helps your therapy remain effective night after night.
Consistent cleaning routines make CPAP therapy easier, safer and more reliable over the long term.
