Collection: AirFit N30i Replacement Parts

The ResMed AirFit N30i is a nasal cradle mask with a tube-up design — the hose connects at the top of your head instead of your chin, which keeps it out of the way if you sleep on your side. It shares most parts with the AirFit P30i.

Nasal cradle cushion: sits under and around the nose rather than sealing over it. Replace every 1–3 months, sooner if it's gone stiff or won't hold pressure.

Headgear and frame: interchangeable with the P30i — if you own both, one set of headgear covers either. Expect to replace the fabric headgear roughly every 6 months.

QuietAir vent and elbow: the vent is built into the elbow on this mask family. A blocked or worn vent is a common cause of noise complaints from a sleeping partner.

Not sure if you have the N30i or the P30i? The N30i's cushion cradles under the nose; the P30i uses two small nasal pillows instead. Check your current cushion before ordering — the cushions aren't interchangeable, even though the rest of the mask is.
