Why the ResMed AirFit 20 Cushion Is Necessary
I’ve found that the cushion is the part of the mask that makes the biggest difference in comfort and performance. With the ResMed AirFit 20, the cushion helps create a reliable seal against my face, which means less air leaking out during the night. That matters because a good seal helps me get consistent therapy without constantly waking up to adjust the mask.
My experience is that the cushion also makes the mask feel much more comfortable to wear for long hours. Since it sits directly against my skin, having a soft, well-designed cushion reduces pressure points and irritation. For me, that comfort is necessary because if the mask feels too harsh, I’m less likely to wear it properly every night.
I also see the cushion as essential because it can wear out over time. Even if the frame and headgear are still fine, the cushion is what usually loses its shape first. Replacing it helps me keep the mask working the way it should, so my therapy stays effective and my sleep stays uninterrupted.
My Buying Guides on Resmed Airfit 20 Cushion
What I Look for in a ResMed AirFit 20 Cushion
When I shop for a ResMed AirFit 20 cushion, my first priority is comfort. I want a cushion that seals well without pressing too hard on my face. Since this cushion sits directly against my skin, I also pay attention to how soft it feels and whether it helps reduce red marks in the morning.
Why the Right Size Matters to Me
I’ve learned that getting the correct size makes a huge difference. If the cushion is too small, I may deal with leaks. If it’s too large, it can feel bulky and uncomfortable. I always check the sizing guide carefully before buying so I can get a better seal and a more restful sleep.

Durability and Replacement Timing
I also consider how long the cushion will last. Over time, I expect wear and tear, especially with regular cleaning and nightly use. I usually replace my cushion when I notice leaks, stiffness, or visible damage, because a worn cushion can affect both comfort and performance.
