How to Clean Your CPAP Properly
Share
Keeping your CPAP equipment clean is one of the most important parts of successful sleep apnea therapy. Regular CPAP cleaning helps prevent bacteria buildup, improves comfort, extends the life of your machine, and protects your health. Whether you use a standard sleep apnea machine, a BiPAP machine, or a modern device like the AirSense 11, learning how to clean your CPAP properly will help you get the best results from your therapy.
In this guide, we’ll walk you through how to clean a CPAP machine step by step, explain how often to clean CPAP equipment, and share best practices recommended by manufacturers like ResMed.
Why CPAP Cleaning Matters
Your CPAP machine pushes air directly into your airway every night. Over time, moisture, skin oils, and dust can accumulate in your CPAP tubing, mask, and humidifier chamber. Without proper cleaning, these areas can become breeding grounds for bacteria, mould, and allergens.
Dirty CPAP equipment may lead to:
- Sinus infections
- Respiratory irritation
- Increased congestion
- Unpleasant odours
- Reduced therapy effectiveness
Routine cleaning of your CPAP equipment keeps your breathing air clean and protects your long-term health.
How Often Should You Clean Your CPAP?
One of the most common questions patients ask is how often to clean CPAP equipment. The answer depends on the part, but consistency is key.
Daily Cleaning
- CPAP mask
- Mask cushion
- Humidifier water chamber (rinse and air-dry)
Weekly Cleaning
- CPAP tubing
- Headgear
- Machine exterior
- Filters (check and replace as needed)
If you’re wondering how often you should clean your CPAP hose, most manufacturers recommend at least once per week, or more often if you live in a humid environment or have allergies.
How to Clean a CPAP Machine Safely
Before cleaning any CPAP equipment, always unplug the device and disconnect all parts. Never submerge the main machine unit in water.
Step 1: Disassemble Your Equipment
Separate the following parts:
- CPAP mask and cushion
- CPAP hose or standard CPAP tubing
- Humidifier chamber
- Headgear
- Filters
This allows you to clean each component thoroughly.
Step 2: Use Warm Water and Mild Soap
The best way to clean CPAP equipment is with warm water and gentle, fragrance-free soap. Avoid antibacterial soaps, harsh detergents, or alcohol-based cleaners.
Good options include:
- Mild dish soap
- Baby shampoo
- CPAP-approved cleaners
This method works for cleaning CPAP machines, masks, and tubing safely.
How to Clean CPAP Hose Properly
Knowing how to clean the CPAP hose correctly helps prevent mould and residue buildup.
Standard Method
1. Fill a sink or tub with warm water.
2. Add a few drops of mild soap.
3. Submerge the CPAP tubing completely.
4. Swish water through the hose.
5. Rinse thoroughly with clean water.
6. Hang to air-dry.
For ResMed CPAP hose models and heated hoses, always check manufacturer guidelines before soaking.
How to Clean Heated CPAP Hose
Heated tubing should be washed gently and never submerged for long periods. Use warm water, mild soap, and allow extra drying time.
How to Clean a CPAP Hose with Vinegar
Some users prefer cleaning CPAP with vinegar for natural disinfecting.
Vinegar Method
1. Mix one part white vinegar with three parts water.
2. Soak the hose for 20–30 minutes.
3. Rinse thoroughly.
4. Air-dry completely.
This method works for cleaning a CPAP hose with vinegar, but it should only be used occasionally. Frequent vinegar use may damage materials over time.
How to Clean a CPAP Mask and Cushion
Your CPAP mask touches your face every night, making regular cleaning essential.
Daily Mask Cleaning
- Wash with warm water and mild soap
- Gently rub the cushion
- Rinse thoroughly
- Air-dry away from sunlight
This method works for nasal mask, full-face mask, and ResMed mask models.
Using a CPAP mask cleaner or CPAP mask cleaner wipes can be helpful when travelling, but they should not replace regular washing.

Best Soap to Clean CPAP Mask
Choosing the best soap to clean CPAP mask equipment helps prevent irritation and damage.
Recommended options:
- Unscented dish soap
- Baby shampoo
- CPAP-specific cleaners
Avoid:
- Bleach
- Vinegar (daily use)
- Essential oils
- Alcohol wipes
- Antibacterial soaps
These harsh products can degrade silicone cushions and cause skin irritation.
How to Clean CPAP Water Tank (Humidifier Chamber)
Your CPAP humidifier adds moisture to therapy air, but it can also trap minerals and bacteria.
Cleaning Steps
1. Empty any remaining water daily.
2. Wash with warm water and mild soap weekly.
3. Rinse thoroughly.
4. Air-dry fully before reuse.
If mineral buildup appears, occasional vinegar rinses may help. Always use distilled water to reduce deposits.
This applies to most CPAP humidifier models, including AirSense 11 chambers.
Cleaning CPAP Machine Exterior and Filters
While you should never wash the main device unit, keeping it clean is still important.
Exterior Cleaning
- Wipe with a dry or slightly damp cloth
- Avoid moisture near vents
- Keep dust away
Filter Maintenance
Check filters weekly. Replace disposable filters every 1–3 months, and wash reusable filters as instructed.
Proper filter care improves air quality and extends machine life.
What CPAP Cleaner Does ResMed Recommend?
Many users ask: what CPAP cleaner does ResMed recommend?
ResMed advises using simple soap and water for routine cleaning. They do not recommend ozone-based CPAP cleaning machines or UV-based devices, as these may damage equipment and void warranties.
ResMed encourages manual cleaning for safety and long-term durability.
Are CPAP Cleaning Machines Safe?
CPAP cleaning machines use ozone or UV light to sanitize equipment. While marketed as convenient, many manufacturers, including ResMed, do not officially support these devices.
Potential concerns include:
- Equipment damage
- Residual ozone exposure
- Warranty voiding
- Incomplete cleaning of visible debris
Manual CPAP machine cleaning remains the safest and most reliable method.
CPAP Cleaning for BiPAP Machines
BiPAP and CPAP machines share similar cleaning requirements. If you use a BiPAP machine, follow the same schedule for masks, tubing, humidifiers, and filters.
The only difference may be specialized tubing or humidifier parts, so always check your user manual.
Best Way to Clean CPAP While Travelling
When travelling, cleaning CPAP equipment can be challenging.
Helpful travel tips:
- Bring travel-sized mild soap
- Pack CPAP wipes
- Use distilled water when possible
- Air-dry parts overnight
This helps maintain hygiene even on short trips.
Common CPAP Cleaning Mistakes to Avoid
Many users unintentionally damage their equipment through improper cleaning.
Avoid:
- Putting parts in the dishwasher
- Using bleach or harsh chemicals
- Drying in direct sunlight
- Skipping weekly hose cleaning
- Reassembling while wet
These mistakes shorten equipment life and reduce therapy effectiveness.
Creating a Simple CPAP Cleaning Routine
A consistent routine makes CPAP cleaning easy.
Example Weekly Schedule
Daily:
- Wash mask
- Empty humidifier
Weekly:
- Clean tubing
- Wash headgear
- Wipe machine
- Check filters
Monthly:
- Replace filters if needed
- Inspect equipment for wear
Sticking to this schedule keeps your CPAP supplies in excellent condition.
When to Replace CPAP Equipment
Even with perfect cleaning, CPAP equipment wears out.
Typical replacement schedule:
- Mask cushion: Every 1–3 months
- Tubing: Every 3–6 months
- Filters: Every 1–3 months
- Headgear: Every 6 months
- Humidifier chamber: Every 6–12 months
Regular replacement improves comfort and hygiene.
