ResMed AirFit F20 Full Face Mask

One of the world's most trusted full face CPAP masks. The AirFit F20's InfinitySeal silicone cushion seals reliably across a wide range of face shapes and therapy pressures. Washable, proven, and simple to use. Small, Medium and Large.

The ResMed AirFit F20 is one of the most widely used full face CPAP masks in the world — and for good reason. Its InfinitySeal™ silicone cushion is engineered to maintain a reliable seal across a remarkable range of face shapes, therapy pressures, and sleeping positions, making it one of the most consistently dependable full face options available. If you breathe through your mouth during sleep and want a proven, washable, straightforward mask that simply works, the AirFit F20 is the benchmark.

Key Features

• InfinitySeal™ silicone cushion — designed to adapt to your facial contours and maintain a consistent seal during movement, even as you shift positions through the night; tested to perform reliably at both standard and higher therapy pressures
• Flexible fabric-lined frame — the soft, padded frame sits comfortably under the eyes rather than across the nasal bridge, providing an unobstructed field of vision and minimal facial contact
• EasyClick™ magnetic headgear clips — secure the mask quickly each night without re-threading straps; particularly useful for users with reduced dexterity in their hands or fingers
• QuietAir™ diffused venting — exhaled air is softly dispersed to reduce noise and airflow disturbance for both the wearer and their bed partner
• Open-frame design — keeps the visual field clear so you can comfortably wear glasses, read, or watch TV with the mask on before sleep
• Interchangeable with AirTouch F20 — the frame accepts both the standard InfinitySeal silicone cushion and the AirTouch F20 UltraSoft memory foam cushion, so you can trial both cushion materials on the same frame
• Three sizes — available in Small, Medium, and Large, with a one-size-fits-all headgear included
• Compatible with bi-level and NIV therapy — designed to perform across a wide pressure range, suitable for both standard CPAP and higher-pressure bi-level prescriptions

Who Is This For?

The AirFit F20 is the right starting point for most people who need a full face mask — particularly those who breathe through their mouth during sleep, whether consistently or when congested. Its broad fit range and forgiving InfinitySeal cushion make it a strong choice for both newly diagnosed patients setting up for the first time and experienced users who want a reliable, easy-to-maintain silicone mask. If you have a smaller face or finer features, the ResMed AirFit F20 Full Face Mask For Her uses a tailored frame sized for narrower facial profiles. If you'd prefer the feel of memory foam over silicone — or want to reduce your daily cleaning routine — the ResMed AirTouch F20 Starter Kit uses the same frame with a soft foam cushion instead.
