Do CPAP systems really get dirty? Yes, they can harbor germs if they’re not cleaned. “The mask sits on the face, in contact with organisms on the skin. Over time, bacteria and oils on a dirty mask may give you a rash or infection on the skin,” says Dr. Epstein.
Another risk — one mentioned in some of those commercials — has to do with the bugs you may breathe in from a dirty water reservoir in the air pump. The water is needed to put moisture in the air you breathe through the mask. Otherwise, the air would be too dry.
“But if the standing water in a reservoir isn’t cleaned regularly, there is the potential for bacteria or mold to grow, which you could breathe in,” Dr. Epstein points out.
“Breathing in those organisms can make you sick or increase problems related to conditions such as asthma, reactive airway disease, or other lung conditions.” If you are frequently getting sick or your CPAP smells moldy, it could be a sign that the device is not clean.
