You should clean your mask daily. Facial oil and dirt can easily build up on your mask parts when they’re not cleaned properly, which can lead to skin irritation. The good news? Cleaning your mask doesn’t take long, so working it into your morning routine should be a breeze.


Time it takes: 5 minutes

Supplies you’ll need to clean your mask:

Sink or tub
Warm, drinking-quality water (86°F / 30°C)
Dish soap (if possible, mild antibacterial)
Daily step-by-step cleaning tips:

Unplug your CPAP machine from the power source.
Disconnect your mask and tubing parts from your machine.
Disassemble your mask into three parts: headgear, cushion and frame.
In the sink, clean your mask cushion and headgear to remove any oils. Gently rub with warm, drinking-quality water and mild soap.
Avoid harsh cleaning products, including dish detergents, which may damage the mask or leave harmful residue.
Rinse again thoroughly with warm, drinking-quality water.
Place the cushion and frame on a towel and allow the parts to dry away from direct sunlight on a flat surface.
