Fisher & Paykel FlexiFit 431 Full Face Under The Chin CPAP / BiPAP Mask

The Fisher & Paykel FlexiFit 431 Full Face Under The Chin CPAP / BiPAP Mask is one of the few masks ever designed with a true under-the-chin seal. Unlike traditional full face masks that sit above the chin, the FlexiFit 431 extends underneath the chin to provide additional support and help reduce air leaks caused by jaw drop during sleep.

This unique design makes the FlexiFit 431 an excellent choice for CPAP and BiPAP users who experience mouth leaks, struggle with maintaining a mask seal, or find themselves constantly tightening their headgear throughout the night.

The patented FlexiFit cushion automatically adapts to the contours of your face, while the Glider Strap technology allows natural movement during sleep without compromising the mask seal. The result is a stable, comfortable fit that remains secure even at higher therapy pressures.

Many CPAP users experience air leaking from the bottom of their full face mask when their jaw relaxes during sleep. While chinstraps may help, they are not always effective. The FlexiFit 431 addresses this issue directly with its innovative under-the-chin design, helping create a more reliable seal and reducing therapy interruptions. Ideal for CPAP and BiPAP users who experience mouth leaks, jaw drop during sleep, lower mask seal leaks, or mouth breathing, as well as those requiring higher therapy pressures and looking for an effective alternative to a traditional chinstrap.
