ResMed AirFit N30i Cushion (Nasal Cradle)

Quick answer: This is the genuine ResMed replacement nasal cradle cushion for the AirFit N30i tube-up mask — the soft cushion that sits under the nose and also serves as the connecting link between the two sides of the SpringFit frame. The cushion is the part that seals and wears fastest, so replacing it on schedule is the single most effective way to stop leaks. Available in Small, Medium, Small-Wide, and Wide. Note: the N30i cushion is interchangeable with the AirFit P30i — but it’s different from the front-connecting N30 cushion. Frame and headgear not included.

What’s included

• 1 × AirFit N30i nasal cradle cushion (in your selected size)

Frame and headgear not included.

About this part

On the AirFit N30i, the cradle cushion does two jobs: it’s the seal (a soft silicone cradle that rests under the nostrils, curving around the sides without going inside them or over the bridge), and it’s also the connecting link that joins the two hollow side-arms of the SpringFit frame, carrying air to the nose.

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 seal.

Sizing: the N30i cradle cushion comes in Small, Medium, Small-Wide, and Wide (color-coded). Getting the size right matters — the cradle needs to sit under the nostrils and seal without blocking them.

Interchangeable with P30i: the N30i nasal cradle cushion is interchangeable with the AirFit P30i — so if you switch between the two masks, the cushions carry over. Note: it’s not the same as the front-connecting AirFit N30 cushion.

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.
