Disassemble the Mask: Remove the mask from the CPAP tubing and separate the headgear, cushion, and frame.
Wash with Warm, Soapy Water: Use mild soap and warm water to clean all mask parts. Avoid harsh chemicals that can damage the materials.
Rinse Thoroughly: Rinse all components under running water to remove soap residue.
Air Dry: Place parts on a clean towel and allow them to air dry completely before reassembling.
Weekly Deep Cleaning
Deep Clean: Perform a thorough cleaning by soaking mask parts in a solution of water and mild disinfectant.
Inspect for Wear: Check the mask for cracks, tears, or other signs of wear and replace parts as necessary.
Recommended Cleaning Supplies

Following these cleaning steps and using appropriate supplies will maintain your CPAP equipment's effectiveness and hygiene, ensuring comfortable and healthy sleep therapy.
Neglecting CPAP maintenance doesn't just affect hygiene — it reduces therapy effectiveness and can shorten the life of your machine. This guide covers every essential supply you need, how often to replace each one, and why it matters. Whether you're using a ResMed AirSense, a Respironics DreamStation 2, or a Fisher & Paykel machine, the same principles apply.
Your CPAP mask sits against your face for seven or eight hours every night. Without the right cleaning routine, bacteria, mould, and skin oils build up — shortening the life of your equipment and disrupting your therapy. This guide covers every major cleaning method, which ones actually work, which ones to avoid, and a simple schedule to keep your ResMed, Fisher & Paykel, or Respironics equipment in top condition.
Your CPAP machine is doing important work every single night. However, it can only do that work well if the supplies around it are clean, functional, and replaced on schedule. Neglecting CPAP maintenance doesn't just affect hygiene — it reduces therapy effectiveness and can shorten the life of your machine.
This guide covers every essential CPAP accessory and supply you need, how often to replace each one, and why it matters. We cover supplies for ResMed, Fisher & Paykel, and Respironics machines — including the DreamStation 2.
Why CPAP Maintenance Actually Matters
It's easy to overlook CPAP cleaning when the machine seems to be working fine. But over time, used filters restrict airflow, dirty tubing harbors bacteria, and worn mask parts leak air. All of these affect how well your therapy performs — even if the machine itself runs quietly.
Beyond effectiveness, there's a hygiene issue. Your CPAP circulates air through parts that collect moisture, skin oils, and in some cases mold, if not cleaned regularly. Staying on top of CPAP maintenance protects both the machine and your health.
The good news is that most CPAP upkeep takes less than five minutes a day. A consistent routine makes it easy.
CPAP Filters: Your First Line of Defense
CPAP filters stop dust, allergens, and airborne particles from entering the machine and reaching your airway. Most ResMed, Respironics, and Fisher & Paykel machines use two filter types.
Disposable filters — Replace monthly. These are thin, white foam filters that catch fine particles. They're inexpensive and should be swapped out on a set schedule, not just when they look dirty.
Reusable foam filters — Clean weekly, replace every six months. These thicker gray filters catch larger particles. Rinse them under warm water, let them dry completely, and reinstall.
If you live in a dusty environment or have pets, consider replacing both filter types more frequently. Restricted airflow from a clogged filter forces the machine to work harder and may affect pressure delivery.
CPAP Tubing: Often Overlooked, Always Important
CPAP tubing connects your machine to your mask. It seems simple — but dirty or cracked tubing is a surprisingly common source of both hygiene issues and air leaks.
How often to replace: Every three to six months, or sooner if you notice cracking, discolouration, or an unusual smell.
How to clean: Wash weekly with warm soapy water. Rinse thoroughly and hang to dry completely before reattaching. Never reattach damp tubing — moisture inside the tube creates the right conditions for mold growth.
Some users upgrade to heated tubing to reduce condensation in the tube overnight. If you wake up with water droplets in your tubing — a phenomenon called rainout — heated tubing solves the problem cleanly. This applies to ResMed AirSense machines as well as Respironics DreamStation and DreamStation 2 users.
CPAP Wipes & Daily Cleaning
CPAP wipes are designed specifically for mask cushions, frames, and machine surfaces. They remove facial oils and residue quickly without damaging silicone components.
Use CPAP wipes every morning after removing your mask. This simple habit extends cushion life significantly and reduces skin irritation caused by oil buildup on the sealing surface.
Standard household wipes, alcohol wipes, or baby wipes are not recommended. They can degrade silicone cushions and leave residues that irritate skin over time.
CPAP Cleaners: Do You Actually Need One?
CPAP cleaners — including ozone and UV-based devices — are marketed as a hands-free way to sanitize your equipment. They're popular, but worth understanding before you buy.
What they do well: Sanitize mask cushions, tubing, and water chambers without soap and water. Convenient for travelers or anyone who struggles with a manual cleaning routine.
What to know: Ozone cleaners require adequate ventilation after each cycle. Some manufacturers note that ozone can degrade certain materials over time with repeated use. UV cleaners are generally gentler on equipment.
Manual washing with warm soapy water remains the gold standard for daily cleaning. A CPAP cleaner works best as a supplement — particularly for weekly deep cleaning — rather than a full replacement for manual washing.

Pairing the Right Accessories With Your Machine
If you're using a ResMed AirSense 10 or AirSense 11, ResMed-branded accessories are always the safest compatibility choice. The same applies to Respironics users — including those on the DreamStation 2 — and Fisher & Paykel machine owners. Brand-matched supplies ensure correct fit, airflow, and warranty compliance. Third-party tubing and filters can work, but verify they match your machine's specifications before purchasing.

Frequently Asked Questions
How often should I clean my CPAP machine?
Wipe your mask cushion daily. Wash your tubing, mask frame, and humidifier chamber weekly. Replace filters and worn parts on the schedule above.
Can I use dish soap to clean CPAP equipment?
Mild, unscented dish soap is generally safe for tubing and humidifier chambers. Avoid anything with moisturizers, fragrances, or antibacterial agents, as these can leave residues or degrade silicone.
What happens if I don't replace CPAP filters?
Clogged filters restrict airflow, which can affect pressure delivery and make the machine work harder. They also allow more particles to bypass filtration and enter your airway.
Are CPAP accessories covered by insurance in Canada?
Many plans cover replacement parts on a defined schedule with a valid prescription. Check with your insurer for approved frequencies and dollar limits.
Do I need a CPAP cleaner or is manual washing enough?
Manual washing is sufficient for most users. A CPAP cleaner is a convenient supplement — especially for weekly deep cleaning — but it's not a replacement for regular manual care.
