ResMed AirFit N20 Nasal CPAP Mask

One of Australia's most trusted nasal CPAP masks. The AirFit N20 features an InfinitySeal silicone cushion that adapts to your face, magnetic headgear clips, and a modular frame interchangeable with the AirTouch N20 foam cushion. Medium and Large.

The ResMed AirFit N20 is one of Australia's most trusted nasal CPAP masks — a proven, washable silicone mask built around the InfinitySeal™ cushion that adapts to your facial contours and maintains a consistent, leak-resistant seal across different sleeping positions. If you breathe through your nose during sleep and want a reliable, easy-to-clean mask from a platform with a long track record, the AirFit N20 is the benchmark.

Key Features

• InfinitySeal™ silicone cushion — the cushion is engineered to adapt to a wide range of facial shapes and maintain a consistent seal during movement; a flexible top section accommodates the natural contours of the nasal bridge while the lower section seals beneath the nose, giving reliable performance across different sleeping positions
• Washable and durable — the silicone cushion can be washed daily with mild soap and water and air dried; with proper care it maintains its shape and seal properties for the recommended replacement interval, making ongoing maintenance straightforward
• Plush open-edge headgear with magnetic clips — the soft, padded headgear is designed to be worn slightly loose, allowing the InfinitySeal cushion to do the sealing work rather than headgear tension; guided magnetic clips connect the lower straps to the frame quickly and securely each night
• Modular frame — interchangeable with AirTouch N20 — the AirFit N20 uses exactly the same frame, headgear, and elbow as the AirTouch N20; you can swap between the InfinitySeal silicone cushion and the AirTouch N20 UltraSoft foam cushion on the same frame at any time, making it easy to trial both materials without replacing the whole mask
• Quick-release elbow with 360° rotation — disconnect from the machine in one move for mid-night trips; the rotating elbow and tube swivel reduce hose drag and allow free repositioning without disturbing the seal
• Two sizes — available in Medium and Large; Small is available in the AirFit N20 For Her

Who Is This For?

The AirFit N20 suits nasal breathers who want a proven, washable silicone nasal mask with a broad fit range and a simple daily cleaning routine. It's a strong first mask for newly diagnosed patients and a dependable replacement for experienced users who know it works for them. If you'd prefer the feel of memory foam over silicone — or want to simplify your maintenance routine to a quick wipe rather than daily washing — the ResMed AirTouch N20 Starter Pack uses the same frame with a UltraSoft foam cushion instead. For smaller facial profiles, the ResMed AirFit N20 For Her is available in Small.
