Description

The ResMed AirFit™ N20 nasal CPAP mask is designed for users who want a reliable seal and consistent comfort throughout the night. Ideal for sleep apnea therapy at varying pressure settings, this nasal mask combines advanced cushion technology with an intuitive design to help reduce leaks and improve overall therapy performance.

At the core of the AirFit™ N20 is the InfinitySeal™ cushion, engineered to maintain a secure seal across a wide range of CPAP and BiPAP pressure levels. Whether you shift positions during sleep or use higher therapy pressures, the cushion adapts to facial contours to help minimize air leaks without requiring excessive strap tension.

Magnetic clips allow for quick and simple mask removal and reattachment, while the quick-release elbow makes it easy to disconnect from your CPAP tubing during the night without removing the entire mask. The soft, flexible frame and plush headgear provide stable yet gentle support, making this nasal CPAP mask a dependable option for both new and experienced users seeking long-term comfort and performance.

Designed for ease of use, stability, and consistent sealing, the AirFit™ N20 supports effective sleep apnea therapy with minimal disruption to your nightly routine.
