The ResMed AirFit F40 Full Face CPAP Mask is a minimal-contact, under-the-nose full face mask that keeps pressure off the bridge of the nose while sealing around the mouth. Its low-profile frame, soft silicone cushion, and easy on/off headgear make it a great choice for mouth breathers, side sleepers, and anyone who wants a clear line of sight and simple nightly use.

Key features & benefits

• Under-the-nose full face cushion helps reduce nasal-bridge pressure and red marks.
  

• Adaptive silicone seal conforms to facial contours for comfort and stability through the night.
  

• Open field of vision (no bulky forehead support) so you can read or wear glasses before bed.
