ResMed AirFit N20 InfinitySeal™ Replacement Cushion
Refresh the seal, restore the silence, and reclaim the comfort that made your AirFit N20 a bedtime favorite. This genuine ResMed cushion features the patented InfinitySeal™ silicone architecture, shaped with varying zones of thickness: a soft contour that rests gently on the bridge of your nose, reinforced side‑walls that anchor the seal when you shift positions, and a flexible under‑lip that adapts as pressure changes through the night.
In an international study, the InfinitySeal cushion fit 99.4 % of faces on the first try, giving users of every facial profile the confidence of a dependable seal without overtightening headgear straps.ResMed Middle East Available in three interchangeable sizes—Small (#63550), Medium (#63551), Large (#63552)—the cushions snap into any AirFit N20 or AirTouch N20 frame (including the N20 for Her) in seconds, so you can experiment with sizing or share a mask frame with a partner who uses a different size.
Because silicone gradually loses elasticity, ResMed recommends replacing the cushion every 30 days (or sooner if you notice leaks or skin irritation). A quick swap keeps therapy pressures accurate, maintains the N20’s open‑field‑of‑vision design, and helps you wake up refreshed night after night.
