FlexiFit 431 Full Face Mask by Fisher & Paykel

Cleverly designed to ensure leak-free therapy, the Fisher & Paykel FlexiFit 431 Full Face CPAP Mask is a comfortable alternative to nasal masks and chin straps. 

It incorporates a unique under-the-chin cushion design, keeping your mouth closed and delivering a stable seal, regardless of jaw movement. 

Featuring FlexiFit technology, the silicone cushion adjusts to the unique contours of your face. The Glider Strap keeps the cushion in place, allowing for head movements without affecting your seal.

With multiple adjustment points, the FlexiFit headgear conveniently fits most head sizes. Plus, there’s no need for further adjustments after the initial mask setup. Thanks to the Easy-Release headgear strap, putting the mask back on only requires reattaching the headgear clip to the frame.

Frequently Asked Questions

How do I clean my F&P FlexiFit 431 Full Face Mask?

Weekly cleaning: headgear

Daily cleaning: frame, cushion, elbow, non-rebreathing valve

  1. Disassemble the mask.
  2. Soak the mask parts in warm water with mild soap. Avoid soaking for more than 10 minutes.
  3. Rinse all parts thoroughly under running water, squeezing out excess water from the headgear. 
  4. Lay parts out to air dry away from direct sunlight.
How often should I replace my FlexiFit 431 Full Face Mask?

To maintain the best fit and seal for your CPAP therapy, we recommend replacing the entire mask, including the headgear and frame, every 6 months.

The silicone cushion, however, may need to be replaced more frequently, typically every 2 to 3 months. Silicone naturally softens over time, which can affect its ability to create a good seal.
My FlexiFit 431 CPAP mask is leaking. What should I do? 
  1. Gently pull the mask away from your face and then release it, allowing the cushion seal to inflate and settle comfortably around your nose and mouth.
  2. Make sure to clean both your mask cushion and your face, as facial oils can interfere with the seal. 
  3. Ensure you're wearing your FlexiFit 431 mask according to the fitting instructions in the user guide. The way you put on the mask significantly impacts the seal.
  4. Adjust your headgear as necessary. 
  5. Try a larger or smaller cushion size. 
  6. Replace any worn out mask parts.

If your CPAP mask still leaks after following all those troubleshooting steps, a different mask style may be a better option. Feel free to contact RespShop for assistance in choosing a different mask.

Long time 431 Flex Fit mask user

I have been using a CPAP machine and mostly this Fisher Paykel Flex Fit 431 at least 20 years. I have tried other masks esp lately when I had to switch to a new Airsense 11 machine from a very old ResMed S9. Initially the CPAP folks sent an under the nose mask to match the Airsense 11 but I lasted 5 minutes with that. I was so used to my 431 that I have had a hard time adapting to much else. I did get my insurance to pay for a brand new frame 431 and new insert which I had been paying for and replacing for years on my dime. I made the mistake early on to change straps which I now know was a mistake. I did adapt ResMed straps for years. When they wear out and get looser I have leaking problems........we shall see what happens tonight when I finally figured out how to adjust the original strap. I think AI and info on the internet does help if you have problems. Oh and now apparently it's ok to use my 431 with my machine even tho they said it was incompatible. WOW

Best in years

I have been using this mask for about 3 years now and I love it. The mask sits under the chin so they're is no need to wear a chin strap. The full mask set comes with a small, medium and large mask so finding the right fit was easy and it made reordering a breeze.

Mask is on the larger side but it's very comfortable. Cushion has lots of surface area to spread out the pressure, so I don't wake up with any marks or lines on my face.

The headgear is a little cumbersome to get on and adjust, but once on it's very comfortable and supple. I've been able to get very good sleep with this mask.

This mask doesn’t seem to be very well known but I was looking for something of its design. In particular, I wanted to find a full face mask with a very large cushion in the idea that it would disperse the weight. This seemed to fit the bill and so I gave it a show. It’s been quite good and I don’t have any complaints about it to speak of.

Cushion. The cushion is very large, cradling around the chin and going up to the top of the nasal bridge, between your eyes. It’s not very sightly or convenient for line of sight, but I like it because it spreads the weight in a large area, particularly on the cheeks. I’ve been able to avoid any red lines while also having a very easy time breathing. The tube points straight down which isn’t my favorite but it doesn’t affect me much anyways.

Harness. The harness is pretty plain Jane, with two parallel bands on each side. It’s not particularly high-tech but it holds the mask on well and doesn’t cause any discomfort. The material could be a little more breathable but it’s not something that’s noticeably affecting my sleep.

This device is too small for the size of my top of nose to under chin. Will not work for me.

The mask is to big and I should have gotten a smaller one. Not your fault I should have gone with a smaller version or another mask that had a smaller version. I am waiting for the VA to send me another one that will be more comfortable to use.

so far so good the adjustments are good the option to size is nice with a small medium and large seal makes it simple to figure out. the release is a big part of this cpap world and this release is easy to release and reconnect.

My first night using this mask was ok, perhaps because I was too tired and not really noticed anything. On the second night, I noticed that the mask and headgear caused some sore on the bridge of my nose with some red marks and sore on the side of my face, and a little air leakage.

I found that if I adjust my upper and lower straps, then things will be ok. There will be no leakage, and no sore or red marks on the face. Tighten the straps just right then these problems will not be noticeable. An acquaintance suggested that I can also use the cushion one size smaller than the one I am using may also help reduce leakage problem. It helps. This is my first full face mask, so I can't compare it with other full face masks. For now, it's working for me now that I am getting used to it.

Does the attachment that goes across the bridge that is the connector brake? If so is it replaceable? How much if so.

Hello, I am sorry that piece you cannot replace. If that breaks you will need to replace the whole mask. Here is that link https://www.respshop.com/cpap-masks/full-face/fisher-paykel-flexifit-431-full-face-cpap-mask-p-522.html
