The ultimate guide to cleaning a CPAP machine (step by step)
CPAP Cleaning Supplies and Tools You Need
For individuals managing COPD, keeping CPAP equipment clean is essential - not just for the device's performance but also for avoiding respiratory irritation. The right cleaning supplies can make this task straightforward and effective.
Basic Cleaning Supplies
Start with the basics: warm, drinking-quality water and mild liquid detergent. These are great for removing oils, bacteria, and debris from your CPAP components.
When it comes to your humidifier chamber, distilled water is a must. Unlike tap water, which contains minerals that can accumulate and harbor bacteria, distilled water ensures your equipment stays clean and efficient.
Drying your CPAP parts is just as important as washing them. Use clean, lint-free towels to prevent scratches or fibers from sticking to delicate surfaces. Steer clear of paper towels, as they can leave behind particles.
For quick, daily mask cleanings, CPAP-specific wipes are a handy option. These wipes are typically free of alcohol and harsh chemicals, making them safe for regular use.
A soft-bristled brush is another essential tool, particularly for cleaning the inside of CPAP tubing. Brushes designed specifically for CPAP hoses are flexible and sized to clean thoroughly without causing damage.
What to avoid:
Some products can do more harm than good. Skip items like:
- Aromatic solutions or scented oils
- Antibacterial soaps
- Dish detergents
- Alcohol or bleach-based cleaners
- Strong-smelling products
These can irritate the lungs or damage your equipment [3].
CPAP Sanitizers and Additional Tools
While CPAP sanitizers using ozone or UV light might seem convenient, they come with risks. Some have been linked to respiratory issues and are not FDA-approved for people with COPD. Stick to FDA-authorized sanitizers if needed, but remember: nothing beats cleaning with mild soap and water.
"Exposure to high levels of ozone gas may worsen a patients' existing chronic respiratory diseases or increase the chance of a respiratory infection."
– Dr. William H. Maisel, Director of the Office of Product Evaluation and Quality in the FDA's Center for Devices and Radiological Health [4]
For a natural alternative, many CPAP manufacturers recommend diluted white vinegar. It's simple, effective, and avoids the risks associated with chemical sanitizers [2][5].
How to Choose Safe Cleaning Products
Safety should always be a priority, especially for those with COPD. Many store-bought cleaning products contain fragrances or volatile organic compounds (VOCs) that can aggravate symptoms [6]. Carefully read product labels and opt for options with minimal, gentle ingredients. Some safe choices include:
- White vinegar
- Baking soda
- Castile soap
- Lemon juice
- Hydrogen peroxide
When using any cleaner, work in a well-ventilated area. If you're sensitive to fumes, wearing a mask can help.
Russell Winwood, a COPD athlete, emphasizes the importance of simplicity:
"White vinegar, methylated spirits [denatured alcohol], lemon juice, and baking soda are all good household cleaners which normally don't cause reactions in respiratory patients" [8].
Stephanie Williams, a respiratory therapist with the COPD Foundation, agrees:
"There may be someone who has a sensitivity to even a natural substance, but in general, if people use vinegar solutions or citrus solutions to clean their homes, those are often less problematic than harsh chemicals" [8].
Research has shown that exposure to chemicals in cleaning products is linked to respiratory issues, including occupational asthma [7]. For COPD patients, this makes choosing the right cleaning products even more critical.
Daily CPAP Cleaning Steps
A daily cleaning routine for your CPAP machine doesn't take much time. As Jennifer Brubaker, PhD, APRN-CNP, a certified nurse practitioner and sleep medicine specialist, explains: "Most cleaning steps take less than a few minutes" [11]. The goal is to make it a regular habit, just like brushing your teeth or washing your face.
Taking Apart Your CPAP Machine
Before you start, always unplug your CPAP machine from the power source. This basic safety step protects both you and your equipment [11].
Begin by disassembling the parts that need daily cleaning. Start with the mask cushion, which is in direct contact with your face. Throughout the night, it collects oils, sweat, and dead skin cells, so it requires the most attention.
Next, remove the humidifier chamber. This component holds water and must be emptied and refilled daily to prevent bacteria and mineral buildup, which could impact your therapy.
Handle all parts carefully to avoid damaging seals or connections that are essential for proper functioning. Once everything is taken apart, you’re ready to clean and dry each piece.
Washing and Drying CPAP Parts
Clean the mask cushion with warm water and a small amount of mild, unscented dish soap [11]. Make sure to wash all surfaces thoroughly.
Rinse the mask cushion with warm, drinking-quality water to ensure all soap residue is removed [3].
For the humidifier chamber, empty out any leftover water completely [9][10]. Wash it using the same mild soap and warm water solution, then rinse it thoroughly. This step is essential to prevent bacteria and mold from growing in stagnant water.
After washing, place the components on a clean towel in a shaded area to air-dry [11]. Avoid direct sunlight, as it can degrade the materials over time and shorten the lifespan of your equipment. Ensure all parts are completely dry before reassembling to prevent mold or bacteria growth.
Before bedtime, refill the humidifier chamber with fresh distilled water [9][10]. Following these steps will keep your CPAP machine clean and ready for use.
Extra Tips for COPD Patients
If you have COPD, there are a few additional steps you can take to protect your respiratory health. Jennifer Brubaker suggests incorporating mask cleaning into your morning routine: "I encourage people to make mask-cleaning part of their morning routine, similar to brushing your teeth or washing your face after you wake up" [11].
If you’ve been sick with a cold, flu, or respiratory infection, it’s especially important to clean all components daily until you’re feeling better [9][10]. This extra care helps protect your lungs from further irritation.
For a quick clean, you can use CPAP wipes [12]. While convenient, these wipes should not replace regular soap-and-water cleaning - they’re better as a backup option.
Lastly, keep track of your filters. Disposable filters should be replaced every two weeks, and reusable filters need weekly cleaning [12]. Staying on top of these replacements ensures your CPAP machine works effectively and safely.

Weekly Deep Cleaning Process
Daily cleaning keeps your CPAP in good shape, but a weekly deep cleaning is essential to tackle bacteria buildup and ensure your machine performs well over time - especially for those managing COPD. This process goes beyond daily care, adding an extra layer of hygiene that’s crucial for your health.
Soaking CPAP Components
Deep cleaning starts with soaking key components like the mask frame, headgear, tubing, humidifier tub, and reusable foam filters [14].
Begin by disassembling these parts from your CPAP machine. For the humidifier chamber, use a diluted vinegar solution - mix 1 part white vinegar with 9 parts water. If there’s stubborn buildup, adjust to 2 parts vinegar and 3 parts water, and let it soak for 30 minutes [13][14][15].
For the mask frame, headgear, and tubing, warm soapy water does the trick. Use the same mild, unscented dish soap you rely on for daily cleaning, letting the parts soak for several minutes. Afterward, rinse everything thoroughly with drinking-quality water [3][14]. This step removes any leftover soap or vinegar residue that could irritate your airways.
Once cleaned, allow all components to air dry completely. This prevents mold and bacteria from forming. After soaking and rinsing, you may want to explore additional cleaning methods.
Using CPAP Sanitizing Devices
Be cautious with CPAP cleaning machines that use ozone gas or UV light, as these are not FDA-approved [2]. Such devices can expose you to unsafe levels of ozone or UV radiation, which is especially risky for those with respiratory issues like COPD.
If you opt for a sanitizing device, ensure it’s FDA-authorized for reducing bacteria and use it only as a supplement to hand-washing [5]. Robert Miller, VP of Sleep Business at Apria Healthcare, advises:
"Because each CPAP brand is different, you should follow the manufacturer's directions for cleaning" [1].
Most manufacturers recommend sticking to hand-washing with mild soap or a diluted vinegar solution instead of relying solely on sanitizing devices. After sanitizing, inspect all parts for signs of wear to determine if replacements are needed.
When to Replace CPAP Parts
Weekly deep cleaning is a great time to check for wear and tear. Replacing parts on time keeps your CPAP functioning effectively and prevents disruptions in your therapy.
- Mask Cushion: Replace every 3–6 months. Look for cracks, tears, discoloration, or a weakened seal.
- Air Tubing: Replace every 3 months, especially if you notice cloudiness, cracks, or persistent odors.
- Humidifier Chamber: Swap it out if you see cracks, cloudiness, or mineral deposits that don’t come off with vinegar soaking.
- Filters: Disposable filters should be replaced every 2 weeks. Reusable filters need weekly cleaning and replacement if they no longer clean properly or show signs of wear.
| Component | Replacement Schedule | Warning Signs |
|---|---|---|
| Mask Cushion | Every 3–6 months | Cracks, tears, poor seal, permanent discoloration |
| Air Tubing | Every 3 months | Cloudiness, cracks, persistent odors |
| Humidifier Chamber | As needed | Cracks, cloudiness, mineral buildup |
| Disposable Filters | Every 2 weeks | Visible dirt, reduced airflow |
| Reusable Filters | As needed (clean weekly) | Won’t come clean, tears, deterioration |
Robert Miller highlights another benefit of regular cleaning:
"There is another advantage to keeping your CPAP machine clean: it helps keep your equipment working longer. And that can save you money" [1].
Preventing Infections and Making Your CPAP Last Longer
Taking care of your CPAP equipment is essential for managing COPD effectively. Proper storage, handling, and cleaning can help prevent infections and ensure your machine lasts longer. This is especially crucial for COPD patients, as respiratory infections can worsen symptoms and lead to serious health issues.
Proper Storage and Handling
To keep your CPAP equipment in good condition, store it in a dry, well-ventilated area, away from direct sunlight. Excess heat and humidity can encourage mold and bacteria growth, which can harm both your health and the machine's performance [16].
Avoid airtight containers or plastic bags for storage, as they can trap moisture and promote mold growth. Instead, place your CPAP on a dedicated shelf or in a clean, dry nightstand drawer where air can circulate around it [16].
When traveling, use a ventilated travel case to protect your equipment. Always air-dry all components completely before putting them away. This small step helps prevent bacterial growth and extends the lifespan of your CPAP machine.
Proper storage also ties into using the right water for your CPAP humidifier.
Why You Should Use Distilled Water
Using distilled water in your CPAP humidifier is important to prevent mineral buildup and maintain hygiene. Unlike tap or well water, distilled water is free from minerals, bacteria, and other impurities that can damage your machine or pose health risks [17].
Minerals in tap water can create scale inside your CPAP, which not only harms the equipment but also provides surfaces where bacteria can grow. For COPD patients, this is particularly risky. Pathogens like Pseudomonas spp., NTM, and Legionella spp. are associated with many waterborne diseases, contributing to 120,000 hospitalizations, 7,000 deaths, and billions in healthcare costs annually in the U.S. [18]. Despite these risks, about 24% of CPAP users report using tap water in their humidifiers [18].
"Humidifier output quality depends on using distilled water to be used in those devices." - Centers for Disease Control and Prevention [18]
If distilled water isn’t available, you can temporarily use purified bottled water or filtered tap water [17]. However, boiling tap water isn’t a solution - it kills microorganisms but doesn’t remove minerals and salts [17].
Using proper water is just one part of maintaining your CPAP. Regular cleaning routines are just as important.
Daily vs. Weekly Cleaning Comparison
Balancing daily and weekly cleaning routines ensures your CPAP remains hygienic and functional. Each type of cleaning serves a specific purpose, helping to prevent infections and extend the life of your equipment.
| Cleaning Type | Components | Primary Purpose | Infection Prevention |
|---|---|---|---|
| Daily | CPAP mask and humidifier chamber | Remove moisture and surface contaminants | Prevents bacterial buildup from overnight use |
| Weekly | CPAP mask, tubing, and filter | Deep disinfection and thorough cleaning | Eliminates remaining pathogens and buildup |
Daily cleaning focuses on removing moisture and surface contaminants from the mask and humidifier chamber. This prevents bacterial buildup from overnight use. For best results, empty the humidifier each morning and let it air-dry [19].
Weekly cleaning involves a more thorough approach, targeting components like tubing and filters that don’t require daily attention. Soaking these parts helps eliminate bacteria and other pathogens that may linger over time [19][15].
These two routines work together to create a complete cleaning system. Daily cleaning addresses immediate hygiene needs, while weekly cleaning provides a deeper level of disinfection. For COPD patients, this consistent care reduces the risk of respiratory infections, which can worsen symptoms or lead to hospitalization.
Conclusion

Regular cleaning helps remove harmful pathogens that can worsen respiratory symptoms or lead to infections. By sticking to a consistent cleaning routine, you can protect yourself from complications while ensuring your CPAP device performs as it should.
Daily and weekly cleaning routines, as described in this guide, play a key role in extending the life of your CPAP machine - typically lasting three to five years with proper care [20]. Daily cleaning of your mask and humidifier chamber clears away surface contaminants, while weekly deep cleaning tackles bacteria and other particles that can build up over time. Skipping these steps can reduce the effectiveness and lifespan of your equipment.
For COPD patients with weakened immune systems, maintaining a regular cleaning schedule is even more critical. Proper hygiene can lower the risk of infections like pneumonia, which can significantly worsen respiratory conditions. This makes CPAP cleaning an essential part of managing your respiratory health.
If you’re finding it challenging to keep up with your cleaning routine or have questions about your equipment, reach out to your doctor or respiratory therapist. They can provide tailored advice, help you refine your cleaning schedule, and even suggest techniques to improve your breathing and overall therapy experience [21].
