About the Multi-Hole Vent

The multi-hole vent is the exhalation vent component that sits at the base of the N30i cushion, allowing carbon dioxide to escape continuously during therapy. It uses a series of small holes to diffuse exhaled air away from the face, providing quieter exhalation than a single open port. The vent is a safety-critical component — ResMed's user guide requires that vent openings are kept clean, unobstructed, and undamaged at all times to maintain safe, effective therapy.

When to Replace

Inspect the vent regularly to ensure the holes are clear and unobstructed. Replace immediately if the vent is cracked, deformed, or if any holes are visibly blocked and cannot be cleared by cleaning. Clean with a soft-bristle brush (such as a soft toothbrush), rinse thoroughly under running water, shake to remove excess water, and air dry away from direct sunlight. Do not use a brush on the AirTouch N30i cushion itself — only on the vent component.
