Quick answer: This is the genuine ResMed replacement cushion for the AirFit F30 compact full face mask — the under-the-nose cushion that seals below the nostrils and over the mouth. It's the part that does the sealing and wears fastest, so replacing it on schedule is the single most effective way to stop leaks and stop over-tightening your headgear. Available in sizes. Frame and headgear not included.
What's included
- 1 × AirFit F30 cushion (in your selected size)
Frame and headgear not included.
About this part
The cushion does the actual sealing work, and it's a consumable by design. The AirFit F30's cushion is the compact under-the-nose design — it seals below the nostrils and over the mouth, leaving the bridge of the nose untouched, which is what gives the F30 its clear field of view and low-profile fit.
But silicone softens, stretches, and loses its shape with nightly use, facial oils, and repeated washing. The wear is gradual, so most people don't notice the cushion itself — they notice they're tightening the headgear more and more to stop leaks. That's the tell: the straps aren't the problem, the seal is. A fresh cushion restores the original fit at normal strap tension.
Note — F30 vs F30i: this cushion is for the front-connecting AirFit F30. The AirFit F30i (tube-up) uses a different cushion — they're not interchangeable.

Care & replacement
Wash the cushion daily in warm water with a mild soap, rinse thoroughly, and air dry away from direct sunlight — facial oils degrade silicone fastest. Replace it roughly every 1–3 months, or sooner if it feels sticky or stiff, looks cloudy or discoloured, has lost its shape, or if you find yourself tightening the headgear to stop leaks.
Frequently asked questions
What's included? The cushion only — the frame and headgear are not included.
Which mask does it fit? The ResMed AirFit F30 compact full face mask (the front-connecting version).
Will it fit my AirFit F30i? No — the F30i (tube-up) uses a different cushion. This is for the front-connecting F30.
Which size do I need? Match your current cushion size (Small or Medium). Use the ResMed AirFit F30 sizing guide if you're unsure.
How often should I replace it? Commonly every 1–3 months, or sooner if it's discoloured, misshapen, sticky, or leaking.
My mask leaks — do I need a whole new mask? Usually not. A worn cushion is the most common cause of leaks, and replacing it costs a fraction of a new mask.
Do I need a prescription? Replacement cushions are generally available without a prescription. Contact us if you're unsure.
Can I get it delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
