AirFit™ N30i

Freedom nasal mask

AirFit N30i is a ResMed Freedom mask designed for active sleepers. Allowing greater freedom of movement for sleep apnoea patients, it features a supple under-the-nose cushion to eliminate red marks on the nasal bridge and an integrated QuietAir vent to offer peaceful night-times.
Product codes: S/SML (63817) M/STD (63819) W/STD (63820) SW/SML (63818).

Designed for active sleepers


The tube-up design of the N30i is engineered to allow patients to sleep in any position without compromising seal or comfort.

The self-adjusting conduit frame helps deliver a snug fit, and the tube-up design with 360(degree symbol) rotation capability keeps pace with every twist and turn. If patients get up during the night, the quick-release elbow is a practical feature.

Quiet nights with QuietAir

A QuietAir vent is integrated into the AirFit N30i’s nasal cushion, gently diffusing exhaled air to limit noise output.1
This whisper-quiet vent emits just 21 dBA2 for a relaxing bedroom environment.

Modular design compatible with AirFit P30i nasal pillows cushion

A modular setup means AirFit N30i and AirFit P30i mask cushions can be used with the same frame type. Switch easily between nasal (N30i) and pillows (P30i) cushions when you need to alter the seal or change contact points.
