Under-the-Nose Comfort with a Classic Multi-Hole Vent

The Replacement AirFit™ N30i Multi-Hole Vent Cushion is designed to restore the comfort and performance of your AirFit™ N30i nasal CPAP mask. Its under-the-nose silicone design sits comfortably beneath the nostrils, providing a secure, comfortable seal while supporting effective sleep therapy night after night.
The cushion is the hardest-working part of your whole setup, and the first to wear out. Silicone gradually absorbs facial oils and hardens, losing the slight tackiness that lets it seal against your skin without pressure. Once that happens, the usual instinct is to tighten the headgear — which is what causes red marks and sore spots. Fitting a fresh cushion is the single most effective fix for a mask that used to seal and now leaks.
Made from soft, flexible, medical-grade silicone, the cushion reduces pressure on the nasal bridge while maintaining a reliable seal. Its integrated multi-hole vent lets exhaled air escape through an array of small vent holes in the front of the cushion, the original N30i vent design. It's quick to remove, clean and replace as part of routine maintenance, and is available in multiple sizes so you can find the most suitable fit while continuing to use your existing compatible frame.

If your cushion is overdue, the rest of the mask usually is too. These are the parts worth checking at the same time.
Regular cleaning extends the life of your cushion and helps maintain hygiene for safe, effective therapy.
A worn cushion is one of the most common causes of mask leaks and disrupted therapy — and one of the simplest things to put right. This under-the-nose cushion is built to the specification of your AirFit™ N30i mask system, with its multi-hole vent and a latex-free silicone build, so fit, seal, and comfort are exactly as intended, without the cost or hassle of replacing the entire mask. Whether you're refreshing a worn cushion or keeping a spare on hand, it's a straightforward way to keep your therapy consistent night after night.
This cushion is a component of a medical device intended for use as part of a complete, compatible AirFit™ N30i, AirFit™ P30i, or AirTouch™ N30i mask system for CPAP or APAP sleep therapy prescribed by a qualified healthcare professional. This listing includes the replacement cushion only — frame, headgear, elbow connector, tubing, and other CPAP accessories are not included and are sold separately.
Always confirm cushion size and mask compatibility before use, and inspect the cushion regularly for signs of wear, damage, or discolouration. Never block or cover the vent. If you experience skin irritation, persistent leaks, or any adverse reaction while using this product, discontinue use and consult your CPAP provider or healthcare professional.

What is the difference between the multi-hole vent and QuietAir™ cushion?
The multi-hole vent is the original AirFit™ N30i cushion design, where exhaled air escapes through an array of small holes on the front of the cushion. The QuietAir™ version uses a diffused vent that ResMed designed to be quieter. Both fit the same AirFit™ N30i frame. Choose the version that matches your current cushion or that your CPAP provider recommends.
How do I know if my current cushion is the multi-hole version?
Look at the front of your cushion, below the nose. The multi-hole version has a clearly visible group of small raised vent holes. The QuietAir™ version has a diffused vent panel instead of individual holes.
Which size should I order?
The easiest way is to order the same size as your current cushion. The size letter is printed on the side of the cushion: S (Small), M (Medium), SW (Small Wide) or W (Wide). If you are unsure, use the official ResMed sizing template, printed at 100% scale.
What is the difference between Small Wide and Wide?
Small Wide and Wide are designed for wider noses with a flatter profile. Small Wide suits smaller, flatter noses and Wide suits larger, flatter noses.
Is the frame or headgear included?
No. This listing is for one replacement cushion only. The frame, headgear, elbow and tubing are not included. The cushion fits onto your existing AirFit™ N30i frame.
Will it fit my mask frame?
It fits the ResMed AirFit™ N30i conduit frame in both small and standard frame sizes. The AirFit™ N30i and P30i masks share the same frame, so it can also be used on a P30i frame. It does not fit masks from other series, such as the AirFit™ N20 or N30.
How often should I replace the cushion?
ResMed recommends replacing the cushion monthly. Replace it sooner if you need to tighten the straps more often, it has lost its spring, therapy feels less effective, or it stays slippery even after cleaning.
How do I clean the cushion?
Clean it daily. Soak it in warm water with a mild liquid detergent, then gently clean it with a soft brush, paying attention to the vent holes. Rinse thoroughly and let it air dry out of direct sunlight. Avoid bleach, alcohol and scented or moisturising soaps.
How do I fit the new cushion?
Remove the old cushion from the frame, then fit each side of the new cushion onto the ends of the frame until it is held securely. Full step-by-step instructions are in the AirFit™ N30i user guide.
Is the cushion latex-free?
Yes. The cushion is made from soft silicone and is not made with natural rubber latex.
Is this a genuine ResMed product?
Yes. This is a genuine ResMed AirFit™ N30i replacement cushion.
