Please note that CPAP mask customer reviews are typically great or terrible because either the mask works or does not work. Since we all have unique faces, it is a trial and error to find “the one” for each person. A mask that is terrible for someone could be the perfect mask for you or vice versa. Sleepnet masks are made in the USA with the latest technology, which provides the most comfortable mask. Four sizes available: S, M, L, XL. For a quick sizing guideline (no guarantee), the distance between the center of the eyes at the nasal bridge down to the concave part below the mouth should be around Small = 3.5″, Medium = 4.0″, Large, 4.5″, Extra Large = 5.0″.
