AirFit™ N30i Cushion

AirFit™ N30i Replacement Cushion | ResMed CPAP Mask Cushion

Sleep Through the Night — Without the Noise, Leaks, or Tangled Tubing

If your current CPAP cushion is causing leaks, leaving marks on your nose, or waking you up every time you roll over, it's time to replace it. The ResMed AirFit™ N30i Cushion is built for active sleepers who want comfort and compliance — not a fight with their mask every night.

Why Replace Your N30i Cushion?

CPAP cushions are the #1 reason for mask leaks, skin irritation, and pressure loss — and most people don't replace them often enough. ResMed recommends replacing your cushion every 1–3 months to maintain a proper seal, protect your skin, and ensure your therapy is actually working.

A worn cushion means:

• Leaks around the nose that reduce your therapy pressure
• Skin breakdown and irritation from degraded silicone
• Noise from air escaping that disrupts your sleep (and your partner's)
• Poor AHI data that skews your sleep report

A fresh cushion fixes all of this — usually overnight.

What Makes the N30i Cushion Different

Curved Cradle Design — Built for Side Sleepers

The N30i cushion uses a curved, under-nose cradle that sits below the nostrils — not over them. This means less facial contact, less pressure on the bridge of your nose, and a seal that holds even when you shift positions in your sleep.

57% Quieter Than the Previous Model

The AirFit N30i features QuietAir™ diffused venting technology, which disperses exhaled air through dozens of micro-perforations instead of directing it as a concentrated stream. The result: significantly less noise for you and the person sleeping next to you.

Soft Silicone That Moves With You

The flexible silicone cushion adapts to the natural shape of your face throughout the night. It's gentle enough for sensitive skin and firm enough to maintain a consistent seal — even at higher therapy pressures.

Top-of-Head Tube Connection = Freedom to Move

Because the N30i routes tubing up and over the head rather than out the front, you can sleep on your side, your stomach, or switch back and forth without tangling, pulling, or breaking the seal. This is the cushion that lets you forget you're even wearing a mask.

How Often Should You Replace It?

Following this schedule keeps your seal airtight, your therapy effective, and your equipment covered under most extended warranty conditions. Many provincial health benefit programs also cover regular cushion replacement — check your plan.

Which Size Do I Need?

The N30i Cushion is available in four sizes:

• Small — Narrower nose bridge, smaller facial profile
• Small Wide — Narrower nose bridge, wider across the nostrils
• Medium — Standard fit, most common size
• Wide — Wider across the nostrils, broader facial profile

Not sure which size? Your size should be marked on your current cushion. If not, refer to ResMed's sizing guide or reach out to our team — we're happy to help.

⚠️ Compatibility Note: This cushion is designed exclusively for the ResMed AirFit N30i nasal mask. It is not compatible with the N30 (without the "i") or any other ResMed mask model.

Frequently Asked Questions

Can I use this cushion on the N30 (non-i)? No. The N30i cushion is designed specifically for the AirFit N30i. The N30 uses a different frame and cushion system.

How do I know when it's time to replace my cushion? Watch for these signs: visible silicone cracking or yellowing, increased leak events in your app data, marks or irritation on your skin after use, or a noticeable increase in noise during therapy.

Does a new cushion fix leaks? In most cases, yes. Cushion degradation is the leading cause of mask leaks. If you've already re-fitted your mask and adjusted your headgear tension, a fresh cushion is almost always the fix.

Is this covered by insurance? Many private health benefit plans in Canada cover regular CPAP supply replacement. Contact your insurer with the product name and SKU (63813) to confirm coverage.
