Tout savoir sur Resmed QuietAir Vent Ring AirFit F40
ResMed QuietAir vent ring for the AirFit F40 — the original vent part that diffuses the exhaled air through micro-holes instead of blowing it out in one stream, weighing 5.6 grams.
Micro-holes instead of a jet
QuietAir is a patented vent that spreads the exhaled air across many small holes rather than pushing it through a single opening. That removes both the hissing and the draught that otherwise lands on whoever sleeps next to you, and it keeps the mask quiet even at higher pressures.
The ring also sets the exhalation pattern the F40 is designed around, so it is not an optional extra — a blocked or cracked ring changes how the mask clears carbon dioxide. You replace it yourself in seconds without tools.

When should you replace it?
How often depends on use. Replace the ring as soon as you find cracks, discolouration, blocked holes or reduced airflow, so the mask keeps working to specification. See also the QuietAir elbow and the mask frame for the same mask, and more mask parts in our range.
