ResMed Airfit X30i Standard Oral Cushion

If your ResMed AirFit™ X30i mask isn’t sealing like it used to (or it’s starting to feel stiff, leaky, or just… worn-out), it’s probably time for a fresh Standard Oral Cushion. This is the replacement cushion that sits comfortably around your mouth to help create a reliable seal, so your therapy stays steady while you sleep.

The oral cushion is a key part of what makes the X30i feel more modern and less bulky than traditional full face masks. When it’s in good shape, it helps reduce leaks, improves comfort, and keeps your mask feeling stable, even if you’re an active sleeper or side sleeper.

Why You’ll Love It

Because a new cushion can feel like a full mask upgrade. A fresh X30i Standard Oral Cushion helps restore that secure seal and comfortable fit. Translation: fewer leaks, less adjusting, and more uninterrupted sleep.
