A straightforward guide on how to remove and attach the vent ring on your AirFit F40 mask.

Is there a "normal" vent ring? One that is not labeled, "QuietAir Vent ring". I don't feel a lot of air coming out of my "QuietAir Vent ring".

Thank you for reaching out. With proper care and cleaning as outlined in your user guide, the exhaust vents and anti-asphyxia valves should remain free of obstruction. Please make sure nothing is blocking these vents on your elbow attachment as they're designed to prevent rebreathing exhaled breath. If you don't see any obstruction but continue to have trouble breathing with your mask, please contact your medical equipment supplier for a full evaluation of your mask and elbow venting, along with further assistance as needed.
