How to Clean and Replace CPAP Supplies: A Simple Schedule
Cleaning and Replacing CPAP Supplies
When CPAP stops feeling comfortable, the machine is rarely the problem. It's usually a worn cushion that leaks, a clogged filter, or a water chamber that needs a clean. Here's a simple routine to keep your equipment working, and when to replace each part, in plain language, from our team.
Your CPAP mask sits on your face for hours every night, and the air you breathe passes through the filter, tubing, and water chamber first. Skin oils break down the cushion, dust builds up in the filter, and moisture collects in the tubing. Parts that are past their prime cause the problems that make people give up on therapy: air leaks, red marks, dry mouth, odors, and noise. A few minutes of cleaning and replacing parts on schedule keeps therapy comfortable and effective. This guide covers what to clean daily and weekly, how often to replace each part, and which supplies we have ready to ship.
In a hurry? The short version
- Every day: wipe the mask cushion, empty the water chamber, and let everything air-dry.
- Every week: wash the mask, tubing, headgear, and water chamber in warm water with mild soap.
- Replace on schedule: cushions and disposable filters monthly or sooner, tubing every 3 months, headgear and water chamber every 6 months.
- Easiest place to start: AirSense 11 filters, 20-pack, $7.49. Or see all supplies.
Signs a part needs replacing
How often to replace each part
| Part | Typical replacement | Why it wears out |
|---|---|---|
| Full face mask cushion | Every month | Skin oils break down the silicone and it stops sealing |
| Nasal cushion or nasal pillows | Every 2 weeks to 1 month | Small contact area, so wear shows up as leaks quickly |
| Disposable filter | Every 2 weeks to 1 month | Traps dust and pollen; a clogged filter makes the motor work harder |
| Reusable filter | Every 6 months (rinse weekly) | Foam or mesh wears and tears over time |
| Tubing | Every 3 months | Moisture and tiny cracks build up inside the hose |
| Mask frame | Every 3 months | Clips and joints loosen, causing leaks |
| Headgear and chinstrap | Every 6 months | Elastic stretches, so you overtighten to compensate |
| Humidifier water chamber | Every 6 months | Mineral buildup and scratches that are hard to clean |
This is the replacement schedule Medicare uses, and many private insurance plans follow something similar. Your coverage may differ, so check your plan. If a part shows wear sooner, such as a new leak or a tear, replace it right away.
Your cleaning routine
✓Every day
- Wipe the mask cushion to remove skin oils
- Empty the water chamber, rinse it, and let it air-dry
- Refill with distilled water before bed
- Hang the tubing so water drains out
✓Every week
- Wash the mask, tubing, and water chamber in warm water with mild, unscented soap
- Hand-wash the headgear and let it air-dry
- Rinse a reusable filter and let it dry fully
- Check the disposable filter and replace if it's gray
!Avoid
- Bleach, alcohol, or scented soaps that damage silicone and irritate your airway
- The dishwasher, unless your manufacturer says it's safe
- Drying parts in direct sunlight, which degrades plastic
- Tap water in the humidifier, which leaves mineral deposits
!Before using ozone or UV cleaners
- The FDA has not cleared ozone or UV devices for cleaning CPAP equipment
- Some can damage parts or void your machine's warranty
- Soap and water is what manufacturers recommend
- Check your machine's manual before using any cleaning device
5 steps to a weekly deep clean
Unplug and take it apart
Unplug the machine. Separate the mask into cushion, frame, and headgear, and disconnect the tubing and water chamber.
Wash in warm, soapy water
Use a few drops of mild, unscented dish soap. Gently wash the cushion, frame, and water chamber. Swish soapy water through the tubing.
Rinse well
Rinse every part with clean water until no soap remains. Leftover soap can irritate your skin and airway.
Air-dry completely
Lay parts on a clean towel, out of direct sun. Hang the tubing so water drains out. Make sure everything is fully dry before reassembling.
Check for wear as you reassemble
Look for tears, stiffness, cloudiness, or stretched straps. This is the easiest moment to catch a part that needs replacing.

⚠️Important to know
- Don't stop using CPAP because of discomfort. Leaks, dryness, and red marks usually have a simple fix. Talk to your sleep doctor or call us.
- Never change your pressure settings yourself. Your prescription sets them, and only your provider should adjust them.
- If you're sick, clean your mask and tubing daily until you recover, and follow your doctor's advice about therapy.
- Only use cleaning methods your manufacturer approves, so you don't damage parts or void your warranty.
Frequently asked questions
Why does my mask leak even though it used to fit?
Most often the cushion has worn out. Silicone breaks down over a few weeks of use and stops sealing. Replace the cushion first. If it still leaks, check the headgear for stretched elastic, and make sure you're using the right cushion size.
Do I need distilled water?
Yes, distilled water is recommended. Tap and bottled water contain minerals that leave white deposits in the water chamber and can shorten its life.
Can I use baby wipes or regular soap?
Use mild, unscented soap. Scented soaps, alcohol, and many household wipes can leave residue that irritates your skin and airway, and can break down the cushion faster.
Will insurance pay for replacement supplies?
Many plans, including Medicare, cover replacement supplies on a set schedule, often with a prescription and proof that you're using the machine. Coverage varies, so check with your plan.
Can I use my HSA or FSA?
CPAP supplies are generally eligible for HSA and FSA funds. Check with your plan administrator to confirm.
How do I know which filter or cushion fits?
Look for the model name on your machine (for example, "AirSense 11") and on your mask frame (for example, "AirFit F20"), plus the cushion size. Bring the part in or send us a photo and we'll match it.
What if my mask just isn't comfortable anymore?
If a new cushion doesn't fix it, a different mask style may suit you better. See our guide to choosing a CPAP mask.
