About this mask
The AirFit N20 is one of ResMed's most popular nasal masks — it covers the nose (not the mouth), for people who breathe through their nose during sleep. Its InfinitySeal™ silicone cushion is designed to adapt to a wide range of facial contours and seal across therapy pressures, so it fits many people well in few sizes. Paired with SoftEdge™ fabric headgear (rolled-edge straps that reduce facial marks), it's built for comfortable long-term wear.
