The traditional nasal mask is a triangular mask fitting over the nose. The mask has a silicone or foam cushion that helps make the fit more comfortable. Nasal masks have many different styles that cater to a wide range of facial structures and features. They are better for higher-pressure settings than nasal pillows.
Newer nasal mask styles include a “cradle” style cushion, which nestles gently under the nose, allowing the bridge of the nose to be free of contact.
