CPAP full face masks cover the nose and mouth and all, or part, of the face with side straps that keep the mask in place. Some hybrid face masks cover the mouth but also have nasal prongs that fit into the nostrils like a nasal pillow.

Nasal masks are triangular in shape and fit over the nose, covering the areas from the bridge of the nose down to the upper lip. They are popular among CPAP wearers because of the wide range of sizes and fits, making finding a perfect mask for any user very likely.

Nasal pillow masks are among the most popular mask choices for CPAP users because of their minimal design. Nasal pillows are the smallest of the CPAP masks and rest on the user's upper lip as it blows pressurised air through two soft nasal tubes that insert into the nostrils, and is secured by straps that go around the head.
