The ResMed AirFit F40 Full Face CPAP Mask combines full-face CPAP coverage with an ultra-compact, under-the-nose design. The AdaptiSeal™ silicone cushion sits beneath the nose while covering the nose and mouth, helping provide a secure therapy seal with less facial contact.
A flexible frame, short tube, quick-release elbow, magnetic headgear clips and QuietAir™ diffused venting create a streamlined mask design for everyday CPAP therapy. The AirFit F40 is available with Small Wide, Medium and Large cushions and Small, Standard and Large headgear.
The AirFit F40 is designed for users who prefer a low-profile full-face mask with an open field of vision and an under-the-nose seal. ResMed specifies a 20 dBA sound power level with the QuietAir vent ring and a therapy pressure range of 4–30 cm H₂O.
