How to Clean A CPAP Machine: Step-by-Step Guide for Beginners

Cleaning a CPAP machine is simple and should be done regularly using warm water, mild soap, and air drying to keep your therapy safe and effective. By washing key parts like the mask, tubing, and humidifier chamber on a routine basis, you can reduce germs, prevent odours, and support comfortable sleep. For Australians new to CPAP therapy, learning the correct cleaning method early helps build healthy habits that last.

Why cleaning your CPAP machine matters

Your CPAP machine pushes air directly into your airway for several hours each night. Moisture from breath and humidification can allow bacteria, mould, and mineral build-up if parts are left unwashed. Poor hygiene may cause congestion, throat irritation, chest discomfort, or unpleasant smells. Regular cleaning also helps parts last longer, which saves money over time, including accessories such as the ResMed CPAP Chin Strap, which benefits from regular care to maintain comfort and effectiveness.

Australian climates can vary widely, from dry inland areas to humid coastal regions. Higher humidity may increase the chance of mould growth, making routine care even more important.

What you need before you start

You do not need special chemicals or complex tools. Most people already have what is required at home.

• Mild dishwashing liquid without fragrance
  
• Warm water
  
• A clean sink or basin
  
• A soft cloth or sponge
  
• A towel for drying
  
• A clean surface with good airflow

Avoid bleach, vinegar, alcohol, antibacterial sprays, or harsh cleaners. These can damage materials and leave residues that may irritate your airway.

Daily CPAP cleaning routine

A short daily routine keeps your mask fresh and comfortable.

Step 1: Unplug and disconnect

Switch off your CPAP machine and unplug it from the power point. Remove the mask from the tubing.

Step 2: Wash the mask cushion

Separate the cushion from the mask frame if possible. Wash it in warm water with a few drops of mild soap. Gently rub away facial oils.

Step 3: Rinse thoroughly

Rinse under clean running water until no soap remains. Soap residue can cause skin irritation.

Step 4: Air dry

Place the cushion and frame on a towel away from direct sunlight. Allow them to dry naturally.

This daily habit can reduce mask leaks and improve comfort. If you are unsure which parts of your mask can be separated, the team at Sleep Warehouse can help you identify the correct method for your model.

Weekly CPAP cleaning routine

A deeper clean once a week keeps the full system hygienic.

Step 1: Disassemble all washable parts

Remove the mask, tubing, and humidifier chamber from the machine. Check the manufacturer guide if unsure.

Step 2: Wash the tubing

Fill the tubing with warm soapy water, cover each end, and gently shake. Rinse thoroughly with clean water.

Step 3: Clean the humidifier chamber

Wash the chamber with warm water and mild soap. If you notice white residue, this is often mineral build-up from tap water.

Step 4: Rinse and inspect

Rinse all parts well. Check for cracks, stiffness, or cloudiness, which may mean replacement is needed.

Step 5: Air dry completely

Hang the tubing over a shower rail or towel rack so water can drain out. Let all parts dry fully before reassembly.

What not to clean with water

The main CPAP unit should never be submerged in water. If dust collects on the outside, wipe it with a dry or slightly damp cloth. Always unplug before cleaning.

Filters should be checked weekly. Products like the AirSense 11 CPAP Filter help keep dust and allergens out of your machine and should be replaced or cleaned as directed, disposable filters need regular replacement, while reusable filters can be rinsed and air dried.

How often should CPAP parts be replaced

Even with good cleaning habits, CPAP components wear out over time.

• Mask cushions usually every 3 to 6 months
  
• Tubing every 6 to 12 months
  
• Filters every 1 to 6 months depending on type
  
• Humidifier chamber every 6 to 12 months

Australian dust levels, pets, and bushfire smoke can affect filter life. Regular checks help maintain airflow quality.

Travel and cleaning tips

When travelling within Australia or overseas, pack a small bottle of mild soap and a clean towel. If water quality is uncertain, bottled or distilled water is a safer choice for washing and humidifier use. Allow extra drying time in humid areas.

When to consider professional help

If you notice ongoing odours, frequent congestion, or visible mould that does not clear with washing, parts may need replacement. A hard reset of your cleaning routine may not be enough.
