Nasal CPAP masks are worn over your nose and are connected to the CPAP machine by a flexible hose (tubing). They are triangular in shape and cover your face from the bridge of your nose to your upper lip. They attach to your head with four point headgear, meaning that the headgear attaches to the mask in four places and wraps around the back of your head. Nasal masks are ideal for those who breathe only through their nose at night, and because they are so minimal, they are the best CPAP masks for side sleepers. However, they can be used in conjunction with a chinstrap for people who partially breathe through their mouth and prefer the lower coverage of the nasal mask. Our nasal CPAP masks are available in cloth, silicone, or gel and are compatible with all CPAP machines. CPAP nasal masks are the most popular style of mask and fit and seal well without causing irritation. To care for your mask, wash it daily with warm water and soap and let it air dry, or use mask wipes. It is recommended that the cushion of the mask be replaced once every three months or sooner if it begins to lose its shape or seal. The entire nasal CPAP mask should be replaced once every six months or when it begins to leak or rip.
