QuietAir™ is a ResMed technology found on selected CPAP masks (via a QuietAir elbow, a QuietAir diffuser/vent, or a QuietAir vent ring) designed to make exhaled air quieter and less direct. The goal: reduce mask noise and the “blowing” sensation felt by you… and your bed partner.
On this page, we explain how it works, which masks use QuietAir, and how to choose a compatible mask based on your needs.

QuietAir: the basics (in 30 seconds)
A CPAP mask always includes an intentional leak (also called a “vent” or “diffuser”). It’s designed to flush out CO₂ and ensure effective therapy. It’s not a defect: it’s normal and essential.
The difference is how that air is released:
- Standard vent: exhaled air often exits as a more concentrated jet → can create noise and an uncomfortable draft.
- QuietAir™: air is diffused through many tiny multidirectional openings spread over a wider area → the flow is broken up, distributed, and typically quieter.

Why QuietAir can be a game changer (especially for couples)
QuietAir is designed to solve two very common irritants:
- Mask noise (often most noticeable around the elbow / diffuser).
- Exhalation draft that can blow toward your face, your eyes… or your bed partner.
On certain models, technical documentation reports measured levels around 21 dBA with QuietAir, with a noticeable difference versus a standard elbow (e.g., ~10 dBA depending on version/measurement).

Where is QuietAir located? (elbow, vent, ring…)
Depending on the mask, QuietAir can be integrated in different ways:
- QuietAir elbow: very common on full face masks.
- QuietAir diffuser / vent: common on nasal masks and some “top-of-head” masks.
- QuietAir vent ring: used on certain newer mask generations.
Important: depending on the bundle and region, some masks may come with a standard elbow or a QuietAir elbow. If your priority is maximum quietness, make sure QuietAir is included — or choose the compatible replacement part.

How to choose a QuietAir mask (quick tips)
You’re sensitive to noise
Choose a mask with a QuietAir diffuser and prioritize proper sizing/fit to reduce unintentional leaks (which can be noisy).
Your bed partner complains about the “air blowing”
QuietAir is often appreciated when exhaled air is directed toward your partner. A QuietAir design typically reduces that “jet” effect.
You move a lot during sleep
A stable mask + QuietAir is a great combo: fewer micro-leaks often means less overall noise. If you sleep on your side, consider minimal-contact designs too.

QuietAir FAQ (the real questions)
Does QuietAir reduce CPAP machine noise?
No. QuietAir targets mask noise (exhalation vent/diffuser). Machine noise depends mostly on the device model, environment, and humidification.
Can I block the vent holes if it bothers me?
No. These openings are essential for safety and effective therapy (CO₂ washout). If exhaled air bothers you, consider a different mask style, adjust fit, or choose a QuietAir version.
Does QuietAir mean “zero leak”?
No. There will always be an intentional leak. QuietAir simply makes it more diffused and often quieter.
