The ResMed AirFit F40 Full Face CPAP Mask with Headgear is an ultra-compact full face mask that delivers full face performance in a minimalist, under-the-nose design. Clinically proven to achieve a 100% universal fit, the AirFit F40 features ResMed’s AdaptiSeal silicone cushion that softly conforms to your facial contours, maintaining a secure seal even as you change sleeping positions throughout the night.
The fully flexible mask frame is covered in soft nylon fabric padding and sits below the eyes, designed for comfort and to reduce facial marks. The under-the-nose design keeps your field of view open for reading or watching TV before bed, while the compact profile helps reduce feelings of claustrophobia compared to traditional full face masks. QuietAir diffused venting is integrated into the cushion for ultra-quiet operation at just 20 dBA, creating a peaceful bedroom environment for you and your bed partner.
Magnetic headgear clips snap on and off in seconds, making the mask easy to put on, take off, and reconnect in the middle of the night. The quick-release elbow allows fast disconnection for bathroom breaks without removing the mask. A flexible short tube with full swivel reduces drag and moves with you, supporting side, back, and stomach sleeping positions.
Available in three cushion sizes (Small Wide, Medium, and Large) and three headgear sizes (Small, Standard, and Large), the AirFit F40 is compatible with all CPAP and BiPAP machines using standard tubing. It is not natively compatible with the ResMed AirMini (requires the Zephair Universal Adapter).
AdaptiSeal silicone cushion softly conforms to facial contours, clinically proven to achieve a 100% universal fit for seal and comfort across a wide range of face shapes and sizes.
QuietAir diffused venting integrated into the cushion provides ultra-quiet operation at just 20 dBA sound power level, creating a peaceful bedroom environment for you and your bed partner.
Magnetic headgear clips snap on and off in seconds for quick, intuitive fitting and removal, with four adjustment points (two upper, two lower) for easy fine-tuning.
Fully flexible mask frame covered in soft nylon fabric padding sits below the eyes, reducing facial marks and providing a comfortable, low-profile feel.
Flexible short tube with full swivel and quick-release elbow reduces hose drag and allows easy disconnection for nighttime breaks without removing the mask.
