The AirFit F40 covers the nose and mouth while remaining very low on the face, so the field of vision remains clear and you can keep your glasses on to read or watch TV in bed. The AdaptiSeal silicone cushion conforms to the contours of the face and maintains contact when the head moves.

• The flexible frame has few adjustment points, so it's easier to put on at night
• Magnetic clips attach and detach in seconds, even in the dark
• The short tube pulls less on the mask when you turn from side to side during the night
