Flexible Full Face CPAP Mask

The FlexiFit HC431 Full Face CPAP Mask with Headgear is one of Fisher Paykel's latest designs. The Fisher & Paykel FlexiFit mask's cushion seals under the chin to offer a stable seal around your face, while the Glider Strap maintains stability as you move throughout the night.

FlexiFit Technology

Fisher & Paykel's FlexiFit cushion allows the mask to contour to the surface of your face while providing an enduring seal. The inner layer of the mask remains stable, while the outer membrane presses gently against your skin.

Glider Strap

The Glider Strap connects the two layers of CPAP cushions. This allows you to move your head without disturbing the position of the cushion, which helps to keep the seal.

Unique Under Chin Design

Unique to the FlexiFit HC431, Fisher Paykel designed for this mask to have an under-chin strap. The under-chin design offers increased stability by adding another point of contact under your chin. With contact points on your forehead, chin, and a strap that wraps around your head, Fisher and Paykel has created a CPAP mask that effectively "locks" into place.

Efficient Air Diffusion

Made with tiny and directional holes to diffuse air away from you and your partner, the Fisher & Paykel FlexiFit's diffusion system ensures that your sleep apnea therapy will be quiet and noninvasive.


The crown shaped headgear offers enhanced stability and works in concert with the under-chin design of the mask. Perfect for patients who wake up often during the night, this mask also comes with quick-releasing straps that can be released in a single motion.

Key Features

  • FlexiFit Technology Contours To Your Face

Reviewers Tip:

People who wake up often during the night will enjoy this mask's one step, quick release headgear attachment that can be re-applied in the dark in just seconds!

One size fits all. The FlexiFit is designed to accommodate most facial shapes and sizes.

If it was after April 2006, yes. A new design was launched that month, and it is compatible with the latest FlexiFit CPAP mask model.

Can I wear this without the chin attachment?

No, the chin attachment is not removable and is a vital part of the mask.

RX Required.
