ResMed Nasal Cushion - AirFit N30i

The ResMed AirFit N30i Nasal Cushion is built for side and stomach sleepers who want a secure seal without a mask covering the face. The cradle-style cushion rests unobtrusively under the nose, using a soft gel material with a frosted surface for a more natural feel against the skin.

Is This the Right Cushion for You?

This is the right replacement part if you already wear an AirFit N30i, AirTouch N30i, or the N30i-compatible AirFit X30i, and need a fresh cushion or want to try a different size. Because this cushion is interchangeable with the AirFit P30i nasal pillows cushion on the same frame, it's also worth trying if you're currently on a P30i and want to test the under-the-nose cradle style instead of in-nostril pillows — no new mask or headgear required.

Why Choose the AirFit N30i Cushion

Built for Side and Stomach Sleepers

Because the cushion sits under the nose rather than covering it, it avoids the pressure points that can come from a full nasal or full-face mask pressed into a pillow while you sleep on your side or stomach.

A Softer Feel Against the Skin

The gel material's frosted surface is designed to feel less like hard plastic or silicone and more natural against the skin, which matters given how much of the night this cushion stays in contact with your face.

A Seal Built to Handle Movement

Sleep apnea therapy only works if the seal holds as you move, and this updated cushion design is built to resist leaks as you shift positions overnight, helping keep airflow and therapy consistent.

One Frame, Two Cushion Styles

Since the N30i cushion is interchangeable with the P30i nasal pillows cushion on the same frame and headgear, you can experiment with both styles — under-the-nose cradle or in-nostril pillows — without buying an entirely new mask.

Quieter With the Updated QuietAir Vent

As of 2021, ResMed updated this cushion, replacing the original plastic front panel with a silicone frame and the original vent holes with the QuietAir vent, which reduces noise emissions to a whisper-quiet level — worth knowing if you or a partner were sensitive to the sound on the earlier version.

Sizing

The AirFit N30i cushion comes in four sizes, color- and letter-coded on the side of each cushion:

Any of these sizes fits any AirFit N30i frame, so if your current size isn't giving you a good seal, you can order a different size and swap it onto your existing mask rather than buying a new frame.

Compatibility

This cushion is compatible with:

• AirFit N30i
• AirTouch N30i
• AirFit X30i

It's also interchangeable with the AirFit P30i nasal pillows cushion, since the P30i and N30i share the same frame and headgear.

Frequently Asked Questions

Will this cushion fit my AirFit P30i mask?

Yes. The N30i cushion is interchangeable with the P30i nasal pillows cushion, since both masks share the same frame and headgear.

How do I know what size to order?

Match the size you're currently using, indicated by the letter on the side of your existing cushion (S, M, SW, or W). If your current size leaks or feels uncomfortable, you can try a different size on the same frame.

What's different about the updated QuietAir version?

As of 2021, ResMed replaced the plastic front panel with a silicone frame and updated the vent design to QuietAir, which significantly reduces noise compared to the earlier version.

Does this work with the AirTouch N30i mask?

Yes, this cushion is compatible with the AirTouch N30i as well as the AirFit N30i and AirFit X30i.

How often should I replace this cushion?

Replace it when you notice reduced seal, visible wear, or discoloration — many users find replacing every couple of weeks with daily use keeps the seal performing consistently, though your timeline may vary.

Do I need a prescription to buy a replacement cushion?

No. Replacement mask parts like this cushion don't require a prescription. A prescription is only needed for the full mask and CPAP machine.
