Does it really matter if my CPAP equipment is a bit dirty?
As you use your CPAP equipment each night, you introduce your breath, dead skin cells and face oils on to the equipment. These things could live on the mask or start cycling through the machine and cultivate mould or bacteria.
Your CPAP will also pick up dust, allergens and germs from the surrounding area and could introduce them into your lungs. This could make it easier to catch an infection like a sore throat, sinus infection or nasal, eye irritation or other illnesses could also occur.
If you do not change the water in your CPAP humidifier every night or clean your breathing tube regularly it can collect dust, mould and bacteria. This warm space is an optimal environment for them to multiply.
