Quick answer: This is the genuine ResMed replacement nasal cradle cushion for the AirFit N30 mask — the soft silicone cradle that sits under the nose, cradling the base and sides of the nostrils rather than sealing inside them. The cushion is the part that seals and wears fastest, so replacing it on schedule is the single most effective way to stop leaks and keep the N30's light, comfortable fit. Available in Small, Small-Wide, and Medium (color-coded). Frame and headgear not included.

About this part
On the AirFit N30, the cradle cushion is the seal — a soft silicone piece that rests under the nostrils and curves around the sides like a crescent, holding the seal without going inside the nose or pressing on the bridge. It's thinner against the nostrils and more substantial near the mask for support, and it's what gives the N30 its minimal, low-profile comfort.
Because it's in direct contact with the skin and airflow, it's the fastest-wearing part of the mask. Silicone softens, stretches, and loses its shape with nightly use, facial oils, and washing. The wear is gradual, so most people don't notice the cushion itself — they notice more leaks or that they're adjusting the headgear more to hold the seal. That's the tell. A fresh cushion restores the original comfortable seal.
Sizing: the N30 cradle cushion comes in Small, Small-Wide, and Medium, color-coded for easy identification. Getting the size right matters — the cradle needs to sit under the nostrils and seal without blocking them.
Note — N30 vs N30i: this cushion is for the front-connecting AirFit N30. The AirFit N30i (tube-up) uses a different cushion — they're not interchangeable.

Care & replacement
Wash the cushion daily in warm water with a mild soap, rinse thoroughly, and air dry away from direct sunlight — facial oils degrade silicone fastest. Replace it roughly every 1–3 months, or sooner if it feels sticky or stiff, looks cloudy or discoloured, has lost its shape, or if you find yourself adjusting the headgear to stop leaks.
Frequently asked questions
What's included? The cushion only — the frame and headgear are not included.
Which mask does it fit? The ResMed AirFit N30 nasal cradle mask (the front-connecting version).
Will it fit my AirFit N30i? No — the N30i (tube-up) uses a different cushion. This is for the front-connecting N30.
Which size do I need? Match your current cushion size — Small, Small-Wide, or Medium (they're color-coded). If between sizes, choose the larger. Use the ResMed N30 sizing guide if unsure.
How often should I replace it? Commonly every 1–3 months, or sooner if it's discoloured, misshapen, sticky, or leaking.
My mask leaks — do I need a whole new mask? Usually not. A worn cushion is the most common cause of leaks, and replacing it costs a fraction of a new mask.
Do I need a prescription? Replacement cushions are generally available without a prescription. Contact us if you're unsure.
Can I get it delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
