If you’re like many people with sleep apnea, CPAP (continuous positive airway pressure) therapy helps you sleep better at night so you can feel better during the day.
But for some, CPAP therapy just plain stinks. Literally, “stinks.”
Robert Miller, Apria Healthcare Vice President of Sleep Business, says, “Over time, it isn’t unusual for your CPAP machine and accessories to give off unpleasant odors.”
Here are the reasons why your CPAP device may smell funny—and what you can do about it.
CPAP machines are potentially breeding grounds for these pesky particles. That’s because CPAP machines use moisture and heat. Bacteria, mildew, and mold thrive in this kind of environment—whether it’s in your mask, filter, tubing, or water reservoir.
Breathing in these organisms can cause nasal infections, sore throats, a runny nose, watery eyes, sneezing, coughing, dizziness, headaches, and pneumonia-like symptoms. Any and all of these effects can make breathing difficult.
If you notice the following, your CPAP machine may have bacteria, mildew, and mold growing on it:

It makes sense—if you use your CPAP every night, your mask is bound to get dirty. Because your mask touches your face, natural facial oils, bacteria, dirt, and dead skin cells collect on it.
The result: your mask begins to smell. Plus, a dirty mask can lead to leaks, which interferes with sleep, causes skin or eye irritation, and hampers the success of your CPAP therapy.
Here’s what you can do to reduce the harmful effects of a dirty mask:
CPAP filters perform an extremely important job: they capture and trap any harmful particles before they enter your CPAP machine and, more importantly, your lungs, which can make you sick.
CPAP filters tend to get dirty rather quickly, especially if your environment has higher levels of dust, debris, microorganisms, and smoke. Adds Apria’s Robert Miller, “The dirtier the filter gets, the less effective it is. And the smellier it becomes.”
Depending on your CPAP machine, it may have both reusable filters and disposable filters.
New products often emit strong, sometimes pungent odors due to the materials used to produce them. This is often referred to as outgassing (or offgassing).
Think of a new car’s smell. That new pillow smell. Fresh paint. All a result of outgassing. And in all these cases, at first the smell is smelly. The same is true of some new CPAP machines.
Typically, the odor will lessen over time. Also, running your CPAP machine for a few hours during the day in a well-ventilated area may reduce the odor more quickly.
Contact your doctor or the CPAP machine manufacturer for other ways to decrease the smell.
Yes, it’s important to keep your CPAP device and accessories clean. But not all cleaners are appropriate. Some contain harsh chemicals that create a potent odor, leave a sticky residue on the surface of your equipment, and even damage your CPAP device.
Keep it simple: clean your CPAP device and accessories using warm water and mild, scent-free soap. Never use harsh household cleansers, such as dish detergents, alcohol, bleach, or antibacterial soap.
If you do and your device smells, let it air out. Chances are, the scent will eventually recede. To ensure the odor doesn’t return, thoroughly rinse your device and all accessories in water.
Also, devices claiming to clean CPAP machines using ozone or UV light haven’t been approved by the FDA, so avoid using them.
The secret to keeping your CPAP device and accessories odor-free: clean them thoroughly and often. Remember, clean your CPAP mask daily and filters, tubing, and humidifier weekly. Apria’s Robert Miller advises, “Know the manufacturer’s recommendations for cleaning and replacement of your CPAP device and accessories, and follow them closely.”
You’ll soon be on the road to success. Sweet!
