Not regularly cleaning your CPAP tubing can lead to you being exposed to mold and bacteria which can lead to infections. This can also lead to allergies and even cause you to break down early, this may void your warranty so you’ll lose out on money.
You should aim to clean your equipment on a weekly basis at least, if you struggle with allergies or have regular respiratory infections then you may want to clean your equipment on a daily basis.
You should use mild dish soap, a soft cloth, and warm water to help clean your equipment. Make sure your equipment is turned off and unplugged before cleaning it and leave everything to dry thoroughly before using it again.
