Key takeaways
- Some CPAP parts need daily care, while others need a weekly or monthly clean, and the manufacturer's schedule should always be followed.
- Mild, fragrance-free soap, warm water, a clean towel and a basin are all you need for a proper clean.
- Bleach, harsh or perfumed household cleaners, alcohol-based solutions, dishwashers and washing machines should be avoided.
- Mask cushions are commonly replaced after 1–3 months, while masks and hoses generally last around 6–12 months.
To help keep your CPAP equipment hygienic and long-lasting, some parts need daily care, and others require a weekly wash. Cleaning is essential, and with the right routine, your CPAP care can also be simple and quick. A step-by-step breakdown of how to clean your CPAP equipment is below. You can also refer to the manufacturer’s manual, as each model differs.
Why regular CPAP cleaning matters
CPAP masks make direct contact with your skin, and moist air moves throughout the system each night. As a result, skin oils, dust, residue, and moisture can build up over time1. Cleaning CPAP equipment daily removes dust, microbes, debris, and mold, and keeps it fresh and comfortable.
What you'll need
You only need a few basic products to give your CPAP equipment a proper clean2. You might also choose to use CPAP-specific wipes for the daily mask wipe-down.
- Mild, fragrance-free soap
- Warm water
- A clean towel
- A basin
How often to clean CPAP equipment: daily, weekly and monthly
The components of your CPAP equipment can be taken apart for individual sanitising. In terms of how to clean CPAP equipment, the routine below acts as a general guide – but the manufacturer's schedule should always be followed.
| CPAP part | Cleaning regularity |
|---|---|
| Mask cushion | Every morning |
| Mask frame and headgear | Daily |
| Humidifier chamber | Daily |
| Hose | Weekly |
| Filters | Monthly |
Daily: mask cushion and humidifier chamber
To remove skin oils, wipe the mask cushion with warm water and mild soap each morning. Alternatively, you can use a CPAP-specific wipe. Empty the humidifier chamber to remove any water and let it air dry. Some manufacturers suggest distilled water in the humidifier to limit mineral build-up. Check your manual to see what applies.
Weekly: mask, headgear and hose
Every week, prepare a bowl of warm soapy water to wash the headgear and mask parts. You can handwash them before rinsing and letting each part air dry. Make sure to do so away from direct sunlight, as it can cause the silicone and plastics to degrade. Keep reading below for the hose cleaning guide.
Monthly: filters and a general once-over
It’s important to check cushions, tubing and seals every month for wear, discolouration and stiffness. This also applies to filters. Different filter parts need different cleaning methods – you can learn more in the filter section below. Monthly checks may differ depending on the CPAP equipment model, so it’s a good idea to check your manual’s schedule.
How to clean a CPAP hose, step by step
Cleaning the CPAP hose weekly helps keep it sanitised and safe to use.
- Detach the hose from the machine and mask
- Run warm water with a small amount of mild soap through it
- Rinse thoroughly until no soap remains
- Hang the hose away from direct sunlight – the shower usually works well
- Reconnect once fully air dried
Cleaning the humidifier chamber and the machine itself
The chamber helps to regulate airflow before it reaches your airway. It does this by holding water, so daily emptying is needed. Washing it weekly in warm soapy water before rinsing and air drying helps keep it hygienic. Remember to check whether your manufacturer's manual suggests using distilled water in the humidifier.
To clean the CPAP machine unit, unplug and wipe the exterior with a slightly damp cloth, keeping water away from openings.
CPAP filters: cleaning and replacing
There are two common types of CPAP filters, and each requires a different approach.
- Reusable foam filters: can usually be rinsed and fully air dried before refitting.
- Disposable fine filters: typically replaced every few weeks depending on dust and environment, and as per the manual.
What not to use on your CPAP equipment
Certain cleaners can damage or degrade parts3. When cleaning your CPAP equipment, avoid using these products:
- Bleach
- Harsh or perfumed household cleaners
- Alcohol-based solutions on CPAP masks or tubing
- Dishwasher
- Washing machine
What about ozone and UV CPAP cleaning devices?
The Therapeutic Goods Administration (TGA) has not approved or listed any ozone gas devices on the Australian Register of Therapeutic Goods (ARTG) as safe or effective for consumers to clean CPAP equipment. ResMed also advises against ozone cleaners and states that its warranty does not cover damage caused by them. ResMed’s user guides recommend cleaning with mild detergent and warm water only, so UV light devices are not recommended either. If you are unsure, check your CPAP manufacturer’s manual and warranty terms before using any cleaning device.
When to replace CPAP parts
CPAP components have varying lifespans. Mask cushions are commonly replaced after 1–3 months, whereas masks and hoses generally last around 6–12 months4. Your specific model’s supplier schedule can confirm when to replace each part. You can find replacement masks, cushions, and accessories in store and online at Blooms, as well as support for CPAP fit and set-up.
Frequently asked questions
How do you sanitize a CPAP machine?
Generally, no special sanitizing device is needed for routine care. Instead, clean your CPAP equipment using warm water and mild soap according to the recommended schedule. Always check your manufacturer's manual for any model-specific cleaning instructions.
How often should you clean your CPAP hose?
As general guidance, a CPAP hose should be washed weekly with warm water and mild soap. Some care guides also suggest cleaning it more often after a cold or when exposed to dusty conditions as part of good equipment hygiene.
Can I use vinegar to clean CPAP equipment?
A diluted white-vinegar soak is sometimes suggested as part of a weekly cleaning routine or for descaling a humidifier chamber. Always rinse thoroughly afterwards and check your manufacturer's manual first, as some brands advise against using vinegar.
What happens if you don't clean CPAP equipment?
Without regular cleaning, skin oils, dust and mineral deposits can build up on CPAP equipment. Components may develop unpleasant odours over time, and cushions, seals and other parts may wear out more quickly, affecting comfort and maintenance needs.
