ResMed AirFit N20 Nasal Cushion

The AirFit N20 cushion is the silicone part of ResMed's N20 nasal mask that actually touches your face. A replacement restores the easy, leak-free comfort of your first night, and the rest of the mask stays in service.

Pick Small, Medium or Large in line with what you wear today. The cushion pushes straight into your existing frame while the headgear and elbow stay untouched, and For Her wearers will find their own option above.

Key Features:

• Moves as you move: Shaped loops in the InfinitySeal membrane flex with you, so rolling from your back onto your side leaves the seal intact.
• Light on the face: A compact cushion over the nose keeps the mask small and light, leaving your mouth free and your view open for reading.
• Quiet as new: Breath leaves through tiny holes in the elbow, not the cushion, so swapping cushions never changes how quiet the N20 runs.
• Latex free: No natural rubber latex goes into the N20, as ResMed confirms in the user guide written for this mask.
• Room to breathe: Your mouth stays uncovered, so you can talk, sip some water or read in bed with the mask already on.

It suits AirFit N20 wearers whose cushion has started to leak, leave red marks or feel slippery, or who are simply due a fresh one. It is also the easy way to try a new size if your current one has never sealed quite right.

Note: Before ordering, look for the N20 name on your frame. Only N20 frames, AirFit or AirTouch, standard or For Her, accept this cushion.

Finding your size

First time on the N20? Print ResMed's fitting template without any scaling, then measure its ruler to be sure the sheet came out true. Hold the cutout over your nose and see which outline matches without covering your nostrils.

Sizes do not carry over from one mask model to another, so measure again whenever you change masks. A mirror helps here, so you can see exactly where each outline sits against your nostrils.

Silicone or memory foam

ResMed builds the N20 two ways around a single frame. The AirFit version wears this silicone cushion, the AirTouch version a memory foam one, and the two cushions swap freely.

Silicone suits anyone who likes a daily wash, since foam is never soaked. Foam has a softer, plusher feel against the nose, which makes it worth a try if silicone has never quite agreed with you.

Changing the cushion

Press the buttons on the elbow to take it off, then hold the frame and pull the old cushion away. The new cushion only goes in one way, so push it into the frame until it sits flat all round.

Clip the elbow back on and put the mask on by placing it over your nose before pulling the headgear over your head. That keeps the new membrane from folding on the first night.

Here's everything that comes in the box.
