ResMed AirFit F20/F30 QuietAir Elbow

QuietAir is a new diffuser vent within the mask elbow. Featuring small multidirectional openings over a widespread area, QuietAir breaks up exhaled air so that it's spread out lightly. While it releases the same amount of air per breath as our existing standard elbow, it's much quieter and gentler.
