How We Really Clean a CPAP at Home (Real-World Routine vs. Manufacturer Guidelines)
By Clay RollysonThere's what the CPAP manufacturers tell you to do for cleaning… and then there's what people actually do at home. I'm Clay from CPAPmyway, and in this article (and the video below) I'm giving you an honest, real-world look at how my wife Caitlin and I clean and maintain her CPAP, side by side with the official guidelines so you can make your own call.
Fair warning: we don't follow every rule to the letter. But Caitlin has never had mold or mildew in her equipment, and it has never looked anything like some of the swamp-water machines that come through our store's door. If you're doing little or no maintenance right now, this routine is a big step up.

The Official CPAP Cleaning Guidelines
Before I get into our real-world routine, here's what the manufacturers recommend. This is the "by the book" standard, and it's the one you should start from.
| Part | Manufacturer Recommendation | What We Actually Do |
|---|---|---|
| Mask cushion | Clean daily | Wipe daily with a mask wipe (every morning) |
| Tubing / hose | Wash weekly in mild soapy water | Rarely wash it; focus on keeping it dry |
| Humidifier water chamber | Empty daily, wash weekly in mild soapy water | Empty and air dry daily, wash about monthly |
| Disposable filter | Change every 2 weeks | Follow the guideline |
| Washable filter | Rinse weekly | Follow the guideline |
| Water | Use distilled water | Softened well water from the bathroom sink |
Quick disclaimer: The "what we actually do" column is just that: what works in our house. It's not the manufacturer's recommendation, and it's not me telling you to skip steps. Follow your equipment's instructions first, and if you change anything, watch closely for odor, discoloration, or residue.
Daily: Wipe the Mask Cushion
This is the one step we never skip. Every morning, Caitlin takes a mask wipe and cleans the part of her mask that touches her face: inside and out, getting into all the little cracks and crevices. On a nasal pillow mask that takes a couple of seconds.
Why it matters:
- It removes face oils and buildup that break down silicone and hurt your seal.
- Doing it in the morning gives the cushion all day to dry, so it's clean and ready when you go to bed.
- Clean cushions last a lot longer. Oil is what makes silicone go soft, sticky, and leaky.
Use a wipe made for CPAP masks, not baby wipes or household wipes, which can leave residue or irritate your skin. Our favorite is the bubble pad in the CPAP Soap 90-day kit. It comes with 90 daily pads plus soap packets for the weekly wash. If you just want wipes, grab CPAP Mask Wipes or the Citrus II Mask Wipes.
The nasal pillow mask is where I see the worst neglect come through our door. If you use one like the AirFit P30i or AirFit P10, those little pillows sit right in your nostrils, so a daily wipe is a must.
The CPAP Hose: Our Honest Take
Here's where we break the rules: we almost never wash Caitlin's tubing.
Think about what's actually in that hose. As long as there's no condensation in it, it's just room air being pulled into the machine and pushed through the tube to your mask. Mold and mildew need moisture to grow. No moisture, no growth.
That changes the moment water gets in there. If you see water droplets or condensation (often called "rainout"), that hose needs attention.
And here's my contrarian opinion: if you're washing your hose weekly and not drying it completely, you may be creating more of a moisture problem than you'd have by leaving it alone. So if you wash it (which is the official recommendation), dry it thoroughly:
- Hang it vertically so water drains out both ends. A CPAP Hose Hanger or a doorway works great.
- Run the machine with an empty, dry water chamber for a while to push air through and dry the inside.
- Scrub with a long brush if you do see buildup. The CPAP Hose Cleaning Brush Set reaches the full length.
Want the whole setup in one box? The CPAP Clean Start Kit includes a wash basin, brush, and hanger.
Fighting condensation? Rainout usually happens when warm, humid air hits a cooler hose. A heated hose like the AirSense 11 Heated Tubing or an insulating Comfort Tubing Wrap helps keep it warm and dry. We're also working on a dedicated CPAP hose dryer, so stay tuned.
Daily: Empty and Air Dry the Water Tank
Every single morning, Caitlin pulls the water tank out of her AirSense 11, dumps the leftover water, opens it up, and sets it out to air dry. At night she refills it and slides it back in.
That's it. It takes ten seconds, and I believe it's the single biggest reason her equipment stays clean. Water sitting in a warm tank all day is exactly how you end up with the slimy, discolored chambers I see in the store.
If your chamber is already cloudy, cracked, or stained, it may be time to start fresh with a new AirSense 11 Water Chamber.
What About Distilled Water?
I'll be completely honest again: Caitlin fills her tank with water from the bathroom sink. We do have a water softener, but it's well water.
The official recommendation is distilled water, and I'm not advising you to switch. Here's the real trade-off as I understand it:
- Distilled water has no minerals, so it won't leave white scale on the heater plate or inside the chamber. That's why manufacturers recommend it.
- Tap water contains minerals that can build up on the metal heater plate and chamber faster. How fast depends a lot on your local water quality.
I think the reason it works for us is the daily dump-and-dry. Nothing sits around long enough to grow. If you're somewhere without access to distilled water for a night or two, it's not the end of the world. But distilled is still the standard, and it's what you should use whenever you can.
Washing the Water Chamber
The guideline is to wash the chamber weekly. Honestly, we do it about once a month. When we do, we use mild soapy water. One CPAP Soap packet mixed into a gallon of water is made exactly for this, and gentle dish soap works too.
- Mix the soap in warm water (a CPAP Wash Basin keeps it separate from the kitchen sink).
- Wash the chamber, plus any other washable parts.
- Rinse very well so no soap residue is left behind.
- Let everything air dry completely before you put it back on the machine.
Why Moisture Is the Real Enemy
If you take one thing away from this article, make it this: keep your equipment dry when you're not using it.
We're in Florida. If you leave something damp sitting around down here, it turns into pond water almost immediately. (Leave it long enough and you might find an alligator living in it.) Mold, mildew, and bacteria all need moisture to grow. Take away the moisture and you take away most of the problem.
That's the thread connecting everything in our routine: wipe the cushion in the morning so it dries all day, empty and dry the tank every morning, and keep the hose dry.
And don't forget your filter. It's what keeps dust and debris out of the air you breathe. If your machine uses disposable filters, the guideline is a fresh one every two weeks. AirSense 11 replacement filters come in multi-packs so you always have one on hand.
Tips for Truckers and Travelers
I know a lot of over-the-road truckers watch our channel, and you don't exactly have a bathroom sink and drying rack in the cab. You can still do the most important step: in the morning, dump the water out the side of the truck, open the tank, and let it sit open in the sleeper for the day. Add a quick mask wipe, and you've covered the two habits that matter most.
Quick Recap: By the Book vs. Real World
Here's the whole routine at a glance. Save it or pin it somewhere you'll see it near your CPAP.

CPAP Cleaning FAQ
How often should I clean my CPAP mask?
Manufacturers recommend cleaning the mask cushion daily. The easiest way is a quick wipe with a CPAP mask wipe each morning, so the cushion can air dry during the day and is ready at bedtime.
Can I use baby wipes on my CPAP mask?
We don't recommend it. Baby wipes and household wipes can contain lotions, fragrances, or alcohol that leave residue on silicone or irritate your skin. Wipes made for CPAP masks, like the bubble pads in CPAP Soap, are designed for the job.
Do I really need to wash my CPAP hose every week?
The manufacturer guideline is weekly. In our experience, the bigger issue is moisture: a hose that stays dry is far less likely to grow anything. If you wash it, hang it vertically and dry it completely before using it again. If you ever see condensation in your hose, clean and dry it right away.
Do I have to use distilled water in my CPAP humidifier?
Distilled water is the manufacturer recommendation because it has no minerals to leave scale on the heater plate and chamber. Tap water can cause mineral buildup faster, depending on your water quality. Use distilled whenever you can.
Why should I empty my CPAP water chamber every day?
Standing water in a warm chamber is the perfect place for slime, mold, and bacteria to start. Dumping leftover water every morning and letting the chamber air dry open is the simplest habit you can build to keep it clean.
How often should I change my CPAP filter?
For disposable filters, the guideline is every two weeks, or sooner if it looks discolored. Washable filters should be rinsed weekly and fully dried before going back in the machine.
What's the best way to dry a CPAP hose?
Hang it vertically over a doorway or on a hose hanger so water drains from both ends. You can also connect it to your machine and run air through it with an empty, dry water chamber to finish drying the inside.
