ResMed AirFit N30i Cushion

This is the silicone nasal cradle cushion for the ResMed AirFit N30i, the part that rests under your nose while the tube runs over your head. A new one gives back the soft, flexible seal that lets you sleep on your side or front without the mask pushing on your nose.

It comes in Small (63813), Medium (63811), Small Wide (63810) and Wide (63812), one cushion per order. The part numbers don't run in size order, so go by the size name when you reorder.

Key features:

• Standard or Small frame: Every cushion size fits both N30i frames, because ResMed sizes the cushion by your nose and the frame by your head.
• Open field of view: Nothing sits over your nose bridge, so glasses and late-night TV are easy, and ResMed recommends it for stomach sleepers too.
• Four sizes, no Large: ResMed makes this cushion in four sizes up to Wide, with no Large, which exists only on the AirTouch N30i fabric cushion.
• Tube over the head: On the N30i the tube meets the frame at the crown of your head and runs up and away from your face as you sleep.
• Same machine setting: Pillows remains the mask type to choose on an AirSense or AirCurve, which is ResMed's listing for the N30i cradle.

It suits N30i wearers whose cushion has gone stiff or cloudy, and anyone moving between sizes on the frame they already have. Mouth breathers who like an under-the-nose seal can find the same idea in ResMed's AirFit F30i full face mask.

Note: This cushion is for the AirFit N30i, not the AirFit N30 with the front tube. ResMed lists the N30i as incompatible with the AirMini.
