Step-by-Step Daily and Weekly CPAP Equipment Cleaning Protocol
A practical daily and weekly CPAP cleaning routine mask cushions, humidifier, tubing, headgear and filters with step-by-step instructions and common mistakes to avoid.
Keeping your CPAP equipment clean is an important part of maintaining comfortable therapy. Your mask sits against your face for several hours each night, while the tubing carries the air you breathe and the humidifier holds water. Over time, facial oils, dust, moisture and residue can build up on these parts. Regular cleaning helps keep your equipment in good condition and can also help your mask maintain a good seal. The good news is that a basic cleaning routine doesn’t need to take long.

Always check your specific equipment instructions. Exact instructions can vary between machines and masks. ResMed’s current cleaning guidance follows this general daily and weekly schedule, but always check the user guide for your particular equipment.
What You Need Before Cleaning
You don’t need specialist equipment for routine CPAP cleaning. Keep these items available:
Warm, drinking-quality water
Mild, fragrance-free soap or liquid detergent
A clean sink or basin
A clean towel
A soft cloth
A soft-bristled brush if your mask instructions recommend one
⚠ Avoid strong cleaning products. ResMed advises against products such as antibacterial soaps, bleach, alcohol-based cleaners and other harsh substances because they can damage mask components or leave unwanted residue.
Two separate routines that serve different purposes. Daily cleaning prevents facial oil and moisture build-up that affects seal quality night to night. Weekly cleaning addresses the deeper maintenance of structural components that accumulate residue more slowly.
Daily CPAP Cleaning Routine
A simple daily routine should focus on the parts that come into regular contact with your face or water. You can usually complete these steps in a few minutes.
1
Disconnect the Equipment
Switch off and unplug firstSeparate all removable components
Before cleaning, switch off and unplug your CPAP machine. Disconnect the mask and tubing from the machine. If your mask has several removable components, separate them according to the manufacturer’s instructions. Never put the CPAP machine itself into water.
2
Clean the Mask Cushion
Daily facial oils affect the sealWarm water + mild detergentCheck cushion material first
The mask cushion is the part that sits directly against your skin, so it should receive particular attention. Facial oils can build up on the cushion and affect how well it seals.
How to clean it: Place warm water in a clean sink or basin. Add a small amount of mild detergent. Gently rub the cushion with your fingers, paying attention to areas that contact your skin. Rinse thoroughly with clean water. Place it on a clean towel to air dry. Don’t scrub the silicone aggressively. Avoid stretching or twisting the cushion unnecessarily. ResMed recommends daily cleaning of silicone mask cushions with warm water and mild soap.
Important: Check your cushion material. Not every mask cushion should be washed in the same way. For example, the ResMed AirTouch F20 uses an UltraSoft memory foam cushion. ResMed specifically says this cushion should not be submerged or washed in water. Instead, it can be wiped with a dry cloth or suitable non-alcoholic wipe. Always follow the instructions for your particular mask.
3
Clean the Mask Vent
Inspect for dust or residueNever poke objects into vent holes
The vent allows exhaled air to escape from the mask. Inspect it regularly for dust, dirt or residue. If your mask instructions allow it, gently clean the vent and surrounding area. Don’t poke objects into the vent holes or damage the vent material. Some mask designs have specific cleaning instructions, so use the manufacturer’s guide when cleaning this part.
4
Empty the Humidifier
Empty every morning don’t top up old waterCheck for cloudiness, cracks, deposits
If you use a humidifier, empty the remaining water every morning. Don’t simply leave yesterday’s water sitting in the chamber and top it up with fresh water. Remove the water chamber, empty it and wipe it with a clean disposable cloth. Leave it open to dry away from direct sunlight. ResMed recommends this as part of its daily humidifier routine.
Check the chamber for: cloudiness, discolouration, cracks, deposits and leaks. If you notice damage, follow theanufacturer’s replacement guidance.
5
Allow Everything to Dry
Away from direct sunlightDon’t seal wet equipment in a bagGood airflow essential
Proper drying is an important part of cleaning. Place cleaned components somewhere clean and dry with good airflow. Keep them away from direct sunlight and excessive heat. ResMed specifically advises allowing mask components and tubing to dry away from direct sunlight. Don’t put wet equipment back together and immediately store it in a closed bag or container.
Weekly CPAP Cleaning Routine
Once a week, give your CPAP setup a more thorough clean. This includes the mask frame, headgear, tubing and humidifier chamber.
1
Disconnect and Disassemble
Unplug before disassemblyOnly remove parts the manufacturer says are removable
Unplug the machine and disconnect the mask and tubing. Separate the components according to your mask’s user guide. You don’t necessarily need to completely dismantle every tiny component. Only remove the parts your manufacturer says can be removed for cleaning.
2
Wash the Mask Frame
Warm water + mild detergentInspect while cleaning look for cracks and wear
Place the frame in warm water with a small amount of mild detergent. Gently clean it with your fingers or a soft cloth. Rinse thoroughly with clean water and place it on a clean towel to dry.
Check the frame while you’re cleaning it. Look for: cracks, loose connections, damaged clips, discolouration, and signs of wear. If a component is visibly damaged, don’t continue using it simply because it hasn’t reached its normal replacement date.
3
Wash the Headgear
Weekly collects sweat and skin oilsNo bleach, fabric softener or scented productsDon’t wring aggressively
Headgear collects sweat, skin oils and hair products over time. Once a week: place it in warm water with mild detergent, gently hand wash it, rinse thoroughly, don’t wring it aggressively, and leave it to air dry. Avoid bleach, fabric softener and strongly scented products. ResMed recommends weekly cleaning of CPAP headgear.
4
Clean the CPAP Tubing
WeeklyWater must pass through the insideNever use a washing machine or dishwasher
Your CPAP tubing should generally be cleaned once a week. Disconnect the tubing from the machine and mask. Fill a clean sink or basin with warm water and add mild detergent. Wash the inside and outside of the tubing. Rinse thoroughly, check for any remaining soap, and allow the tubing to air dry completely. Make sure water passes through the inside of the hose during cleaning.
ResMed recommends weekly cleaning for standard and heated air tubing. ResMed specifically advises against washing air tubing in a washing machine or dishwasher because it can damage the material.
5
Clean the Humidifier Tub
Weekly thorough cleanCheck instructions before using vinegar or dishwasher
Once a week, give the water chamber a more thorough clean. Wash it in warm water with mild detergent, rinse it thoroughly and leave it to dry. Some ResMed guidance also gives a diluted vinegar solution as an option for certain humidifier tubs. However, always check your specific water chamber’s instructions before using vinegar or putting the chamber in a dishwasher.
6
Wipe the CPAP Machine
Never submerge in waterClean, dry cloth onlyKeep water away from electrical components
The machine itself doesn’t need to be submerged or washed. Instead: unplug it, use a clean dry cloth to wipe the exterior, remove visible dust around the outside, and keep water away from electrical components and openings. ResMed recommends weekly cleaning of the machine exterior.
What About the CPAP Filter?
The filter doesn’t need to be washed unless the manufacturer specifically says that the particular filter is washable. Many CPAP machines use disposable filters, so the important routine is to inspect them regularly and replace them according to the manufacturer’s instructions.
Check, Don’t Wash Unless Your Filter Is Specifically Listed as Washable
Disposable and washable filters are not interchangeable check your machine’s user guide
Check for: dust, grey or brown discolouration, damage, moisture, and blockage. Never operate your CPAP machine without the appropriate filter installed. Your machine’s user guide should tell you whether the filter is disposable or washable and how often it should be replaced.

Common CPAP Cleaning Mistakes to Avoid
🧴
Using Strong Soap
You don’t need powerful antibacterial or scented cleaning products. Harsh products may damage silicone and other mask materials or leave residue. Use a mild product recommended by your equipment manufacturer.
🧪
Using Alcohol on the Wrong Mask
Alcohol can damage certain mask components. This is particularly important for memory foam cushions. ResMed advises keeping the AirTouch F20 memory foam cushion away from liquids and using only appropriate cleaning methods.
💧
Leaving Water in the Humidifier
Don’t leave old water sitting in the chamber indefinitely. Empty it each morning and allow the chamber to dry before the next use.
☀️
Drying Equipment in Direct Sunlight
Direct sunlight and excessive heat can accelerate deterioration of some CPAP materials. Air dry components somewhere clean and out of direct sunlight.
🚿
Washing the CPAP Machine
Never immerse the machine in water. Only clean the exterior as instructed by the manufacturer a clean, dry cloth is the appropriate method.
⚗️
Using Ozone or UV Cleaning Devices Without Checking
ResMed states that ozone and UV cleaning products have not been validated for use with its masks, and repeated ozone exposure may cause damage to ResMed machines. Follow the manufacturer’s recommended manual cleaning procedure.
How Long Does CPAP Cleaning Take?
☀️
Morning Routine
3–5 minutes
Clean the cushion, empty the humidifier and leave components to dry. The exact time depends on your equipment and how many components your mask has.
📅
Weekly Routine
Around 10–15 minutes
Wash the frame, headgear, tubing and humidifier chamber, then wipe the machine exterior. The exact time depends on your equipment and setup.
When Should You Replace a CPAP Part Instead of Cleaning It?
Cleaning can’t repair worn equipment. Inspect your supplies regularly and consider replacement if you notice any of the following:
Cracked silicone
Torn cushions
Persistent leaks
Damaged tubing
Stretched headgear
Broken frame components
A cracked humidifier chamber
A visibly damaged filter
💡 Cleaning and replacement are two separate parts of CPAP maintenance. If a component is damaged, follow the manufacturer’s replacement instructions rather than trying to repair it yourself. Regular cleaning and regular replacement work together one does not substitute for the other.
A Simple CPAP Cleaning Routine to Remember
You don’t need a complicated system. Think of it this way:
💡 The Two-Rule Cleaning Aide-Mémoire
Every dayFace + Water. Clean your mask cushion. Empty and check your humidifier. These are the parts most affected by daily use.
Every weekWhole Setup. Clean the frame, headgear, tubing and humidifier. Wipe the machine. Inspect the filter and equipment for damage.
Replacement Supplies from CPAPstudio
For replacement supplies, CPAPstudio has a range of masks, mask cushions, tubing, filters, headgear and CPAP accessories helping you find the correct replacement parts when cleaning reveals worn or damaged equipment.
Cleaning your CPAP equipment doesn’t have to become a time-consuming chore. A few minutes each morning and a slightly more thorough clean once a week can keep your equipment in better condition. For most standard CPAP setups, the key routine is simple: clean the mask cushion daily, empty the humidifier daily, and wash the mask frame, headgear, tubing and humidifier weekly. This broadly matches current ResMed and NHS guidance.
However, CPAP masks and machines aren’t all made from the same materials. Memory foam cushions, heated tubing and different humidifier systems can have specific care requirements. Always check the user guide supplied with your particular machine and mask before using a cleaning product or method.
