ResMed AirFit N20 Cushion

On the ResMed AirFit N20 nasal mask, the silicone cushion is the part that wraps around your nose and keeps the air where it belongs. Replacing it brings back a soft, even seal, so the mask stays comfortable on gentle strap settings.

It comes in Small (63550), Medium (63551) and Large (63552), with one cushion in each order. It pushes into the N20 frame you already have, so your headgear and elbow carry over unchanged.

Key features:

• Shared with For Her: The AirFit N20 for Her uses these same codes, and since that mask comes in Small only, its match is 63550.
• One code per size: ResMed sells this cushion under the same three numbers in its US and UK shops, so there is one part per size to look for.
• Below the eyes: The N20 frame sits under your eyes, a fit ResMed suggests for side sleepers, glasses wearers and anyone reading in bed.
• Latex statement: Natural rubber latex is not used in the N20, according to its user guide, and ResMed's UK cushion listing agrees.
• Same machine setting: ResMed has you leave AirSense and AirCurve machines on Pillows for the N20, even though it is a nasal mask.

It suits N20 wearers whose cushion has lost its softness, and anyone moving to a new size without replacing the frame. If you would rather have nothing around the bridge of your nose, the AirFit N30i cradle sits just beneath it.

Note: This cushion is for the AirFit N20 family. The AirFit N30, N30i and P10 use different cushions, and the N20 vents through its elbow, not its cushion.
