Known as the QuietAir™ elbow, the F20 elbow is designed for peace and quiet. The QuietAir diffuser vent minimises noise and gently disperses exhaled air, making the AirFit F20 mask whisper-quiet at just 21 dBA of noise. <br></br>
Called the QuietAir™, the ResMed F20 Elbow features a super quiet elbow mechanism which diffuses the air, delivering improved comfort for everyone within earshot.
At only 21 decibels, which is the equivalent of a quiet rural valley or mountain slope environment, the ResMed QuietAir diffuser vent minimises noise and gently disperses exhaled air, making your F20 Mask quieter than any other mask before.
This means that it is 9 times quieter* and provides a 70% gentler exhaled air flow than ever before.
Without the QuietAir feature, the decibel rating of other CPAP masks reaches around 30 and over, which can make a difference in the bedroom at night.
