· 9 mins read

Continuous positive airway pressure (CPAP) therapy is the most common and effective treatment for obstructive sleep apnea and other sleep disorders. CPAP machines rely on CPAP hoses to deliver the appropriate air pressure level for the user’s sleep apnea needs. However, failing to properly clean them can interfere with this function.

Continue reading to learn why, how and when you should clean your CPAP hose, and other tips for the maintenance of your CPAP machine.

Why You Should Clean Your

Regular cleaning of your CPAP mask and CPAP tubing is just as important as using your CPAP equipment every night. Cleaning your CPAP equipment and regularly changing the distilled water of its water chamber (or humidifier chamber) has several benefits, which include:

Infection Prevention

The wet and warm environment fostered in a CPAP hose is the ideal breeding ground for bacteria, mold, and other harmful microorganisms. If these germs aren’t removed, they can cause upper respiratory infections, such as sinus infections, and infections of the lower airway, such as pneumonia. 

Decreasing Allergic Reactions

Dust, pollen, dead skin cells and other allergens can accumulate in your CPAP hose, which can cause allergic reactions. Regularly cleaning your CPAP machine can help remove these potential allergens, therefore reducing the risk of allergic reactions.

Extending the Lifespan of Your CPAP Hose 

Dirt, oil, sweat, and dead skin cells build up in your CPAP tubing, and they can cause damage and break down over time. If you clean your CPAP hose regularly, its lifespan will increase, and you will avoid premature wear and tear. This can save you money since you won’t need to pay for costly repairs or replacement parts as frequently.

Improves the Performance of Your CPAP Machine

If your CPAP hose is not properly cleaned, the effectiveness of your CPAP therapy can decrease, and will make it harder for you to breathe at night. Regular cleaning of your CPAP hose ensures that you receive the right air pressure for your sleep apnea treatment.

Improved Quality of Sleep

When you have a clean CPAP hose, you can be sure that you are breathing clean, fresh air. This can help improve the quality of your sleep, since poor air quality can cause sleep disturbances and nighttime cough.

Avoiding Unpleasant Odors

If your CPAP hose hasn’t been cleaned for a long time, it can develop an unpleasant smell that will decrease the comfort of using your CPAP machine at night.

Preventing Dryness and Irritation

The buildup that happens in dirty CPAP hoses can impair the CPAP humidifier functions, resulting in dry mouth, and nose and throat irritation upon waking up. 

Regularly cleaning your CPAP hose not only facilitates the proper functioning of your CPAP machine, but it also improves your overall quality of sleep, health and well-being.

Cleaning Products for Your CPAP Hose

There are several CPAP cleaning supplies available, but not all of them are suitable for all your CPAP parts. You should always use fragrance and alcohol-free cleaning supplies that are approved to be used in your CPAP equipment, to avoid damaging your CPAP machine and leaving toxic residues behind. These are some of the most commonly used cleaning products:

Gentle CPAP Soap / Pre-wash Solution 

Mild soap or pre-wash solution along with warm water is a great combination to clean your CPAP mask, as well as your mask cushions, humidifier tank, disposable filters and hose. You can wash all your CPAP equipment with warm soapy water to disinfect it and avoid damaging its components. 

Dish soap is usually a great mild detergent to clean your CPAP equipment. However, in some cases these kinds of soaps can be too harsh for the silicone parts of your CPAP machines, so it’s better to try to stick with a special soap designed to clean your CPAP mask and hose.

Step-by-Step: How to Clean your CPAP Hose Effectively?

Cleaning your CPAP hose and the other parts of your CPAP machine is a simple process that can be done in a few simple steps. 

1. Unplug your CPAP machine:

Always make sure that your CPAP machine is fully unplugged before you clean it to avoid any malfunction.

2. Disconnect the hose from your CPAP machine:

Follow the manufacturer’s instructions for this step to ensure that you don’t damage your CPAP machine. Make sure that you disassemble every part of your CPAP machine, including the tubing, water chamber and mask.

3. Clean the hose with soap and water:

Fill a sink or bowl with warm water and a mild soap or cleaning solution. Then place your CPAP hose in the water and move it around for a few minutes.

4. Use your CPAP cleaning brush:

Insert a CPAP hose cleaning brush into one end of the hose, and push it carefully all the way through the other end of the hose. Move the brush back and forth several times to remove any buildup that may have formed.

5. Rinse your CPAP hose with water:

Once you are done with the brush, rinse your hose thoroughly with water until all the debris and soap have been washed away from the inside and outside.

6. Hang the hose to dry:

you can hang your hose to air-dry in a towel rack or shower rod. You need to wait until the hose is completely dry to reconnect it to the CPAP machine.


When cleaning your CPAP hose, you can also take the time to clean the other parts of your CPAP machine. However, with CPAP cleaning machines you can clean all your all CPAP supplies at once:

  • •Clean your CPAP mask: You can use CPAP mask wipes or a damp cloth to keep your CPAP mask clean and free of debris that accumulates over time.

  • •Clean the water chamber: You’ll need to empty the water chamber, and then clean it with a mix of mild soap or cleaning solution and warm water. Then, you have to scrub the chamber thoroughly, and rinse it with water. Dry it with a clean towel, and then you can fill it again with distilled water

It’s important to fill your CPAP water chamber with distilled water instead of tap water, since distilled water doesn’t contain the minerals you can find in other types of water, which can create buildup inside your water chamber and damage your CPAP machine.

CPAP Hose Cleaning Frequency: How Often Should You Do It?

As a general recommendation, your CPAP tubing should be cleaned weekly. Other CPAP parts that should be cleaned weekly are reusable filters, CPAP masks and headgear. Your CPAP mask cushion should be cleaned daily. 

How often you should clean your CPAP machine is going to depend on several factors:


If you use your CPAP machine every night, you should do a weekly cleaning of your CPAP hose. However, you can do it more sparingly if you use it less frequently.


If you live or store your CPAP machine in a dusty or humid place, you may need to clean your CPAP hose more frequently. If your CPAP machine is in a humid place or is constantly getting covered with dust, debris buildup inside the hose can increase, which in turn will increase the risk of respiratory infections.

Health conditions:

If you have a weakened immune system or are currently suffering from an upper or lower respiratory infection, daily cleaning of your CPAP machine is recommended to reduce the risk of catching an infection or worsening the current one.

The water tank of your CPAP machine should be cleaned weekly, but you need to change the distilled water inside of it daily. If you are using disposable filters, you should check them every week, and change them when they appear dirty or according to manufacturer’s instructions. 

General Maintenance of Your CPAP Machine

As for the general maintenance of your CPAP machine, this is how often you should check the different parts of your CPAP device:

  • •Check the mask cushion and pillows for deterioration monthly.
  • •Check the humidifier or water tank for cracks and pits monthly.
  • •Check the CPAP tubing for holes and tears every three months.
  • •Check the mask headgear or chin strap for loss of elasticity every six months.
  • •Check the reusable filter at the back of your CPAP machine for buildup dust and debris every six months.
  • •Get the pressure of your CPAP machine tested at an accredited outlet every two years. 


Below, we give you the answers to some of the most common questions CPAP users currently ask about the cleaning of their CPAP hose:

What Happens if I Don’t Clean My CPAP Hose?

If you don’t clean your CPAP hose regularly, bacteria, mold and other microorganisms can accumulate in the hose and cause upper and lower respiratory infections, such as sinusitis and pneumonia, as well as other health problems related to the respiratory system and the skin. 

Furthermore, if your CPAP hose has too much buildup from being dirty for long periods of time, there can be damage and leaks in your CPAP system. This will not only harm your CPAP hose, but also your pocket as you’ll need to replace them more often, and the effectiveness of your CPAP therapy, as the CPAP machine won’t be able to consistently deliver the right air pressure level for you.

How Often Should I Replace My CPAP Hose?

CPAP hoses should be replaced every three months, but this can change according to its usage and condition. As time passes, your CPAP hose can become damaged, which makes it less effective, as leaks can form, and increases the risk of infection since germs have another point of entry to the CPAP system.

Can UV Light and Ozone be Used to Clean a CPAP Machine

UV light and ozone can certainly be used to clean a CPAP machine, as long as they are used correctly. These methods are great for killing the bacteria and other germs present in your CPAP machine, but they are not as effective at removing buildup dirt and oils.
