  • Fit well

    It fit well but it hard to tell how well it works cause I need a better CPAP machine

  • it works

    I have been using the Flexfit for 10 or more years, my only problem is with the idiotic people at Medicare and the insane requirements to file a claim with them. Anyone that wants Medicare for all should have to suffer through a year with Medicare and they would rapidly change their mind. PS it is a great mask, no problems with the Flexfit.

  • Mask rating

    Mask strap is hard to attach into the female clip. Maybe with time I will get the hang of it. Also, the female clips seem to be attached to each other with a plastic wire ( it mat be metal wire with a covering of plastic, do not know ). If plastic, what, if any, problems have you encountered with this product ?

    The mask did not fit at all. I tried the small. medium and large cushion and none of them made a seal. A very uncomfortable mask.

  • Difficult to get a good seal.

    It seems difficult to get a really good seal.

  • A very good mask for the money for the money!

    The Flexfit 431 is a really good mask with the 3 sizes included so you can get a good fit without having to buy 3 different cushions. One thing I would like to see would be a foam cushion for the 431 Flexfit. I had a slight problem with sealing around my cheeks and think the foam would help with the sealing on the face. I like the way the cushion had the piece under the chin to help hold the mouth closed as I am a "mouth breather".

    It didn't fit very well. It would be better if I could heat the plastic to form to my face better.

  • Not for me

    I am used to F&P Simplus mask and this one is just too rigid for me. It still has good cushioning, but being larger than the Simplus it just isn't as comfortable to me. However, I do honestly believe F&P have the best and most comfortable CPAP masks on the market today. I will be returning this one, however.

  • very dissatisfied

    I tried this product once before. The air leaked out at only 11.5 CM H2O (low pressure). Eventually the frame cracked making it useless. The mask part aged and went gummy. I meant to order a different mask this time, but made a mistake.

  • Good Price, Speedy Delivery and Convenient

    I've used a CPAP for years. Local costs for supplies are outrageous. CPAPExchange made the purchase easy, the prices were as good as any I've found, and my order was received in a few days. Highly recommended.

  • It dosen't work

    I can not keep the air from blowing out the sides no matter what size I use or how tight I make the mask. I guess it can't take 17 lbs. pressure. Tried for two weeks. NO GOOD.

  • Very good mask

    This mask fits very well and has minimal leaks. Comes with the best headgear I have used. Lots of adjust-ability for a custom fit. Had to work with it a bit to get the correct fit, but once dialed in, this is a very comfortable mask.

  • Poor review

    It does not fit right and looses air during the night. I wore it one night and I had to strap it down so hard to work it left marks on my face for three days.

  • Just Keep Adjusting

    Finding the right fit for this mask is difficult, largely due to the fact that there are 6 points of adjustment. I have yet to find a solution that is entirely leak free, but after 2 weeks it is finally not drying my eyes out every night.

  • FlexiFit 431 Full Face Mask

    THE MOST comfortable and quiet mask I have ever used. The headgear actually makes sense, and is adjustable to just the right position and snugness for a comfortable fit. I'll be back!! Excellent!!

  • FlexiFit 431 Full Face CPAP Mask

    This mask is very soft and comfortable; however, it is too soft. The mask cushion collapses serveral times per night. The noise that resulted from this woke me up many nights. If you try this mask, purchase the insurance with it in case it does not work for you. This mask is being returned. I am returning to my Quattro Mask.

  • flexfit 431

    I am having a problem with leaking after the pump reaches top pressure. Am waiting for appt with my sleep doctor to see if a reduced pressure is in order. I'm using the medium pillow, the other two are out of question.

  • FlexiFit 431 Full Face CPAP/BiPAP Mask FitPack with Headgear

    Absolutely LOVE this face mask! Have tried at least half a dozen & gave up for a while--until I tried FlexiFit 431 Full Face mask. It DOES NOT leak, DOES NOT leave indented marks on the face next day, & I DO NOT take it off during the night unknowingly. Keeps my mouth closed (even w/damaged jaws from RA). Do buy it!

  • Two weeks for my new mask.

    My order came very quickly, and was in good condition when I unpacked it. The mask connections fit perfectly with my existing machine the first time. It took a few tries to get the straps adjusted correctly, but even with my chin beard, the mask fits well. Even when moving from left to right sides to sleep, the hose does not pose a problem. Only problem is finding a sleeping position for my head that does not cause the mask to leak. Tightening helps, but becomes uncomfortable.

  • Mask Great! Headgear Not So Much

    Just got the mask a couple of days, ago. Shipping time was excellent. While trying on the mask multiple times, selecting the right size cushion, one of the Velcro strips pulled off of headgear. It was heated, glued or pressed, don't really know. Another mask/headgear from a different company does it the same way, that I have had for almost six months, with no issues. To solve problem, I had to break out needle and thread, and band aid afterwards to make it work that night. Liked the way the mask fits, though it puts too much pressure on bridge of nose. Adjusted every which way to correct, but could not. Need to get pad to go on nose bridge to fix that.

  • Comfortable, reliable fit

    I've been a long time user of the Hans-Rudolph V7300 FFM. I really liked that mask because it has built in chin support and easily molded to fit my face, being that is was a soft mask. However, even with that, I still had to make the straps fairly tight due to my high pressure. I decided to give the FlxiFit 431 a try. I'm impressed! Since it comes with all three sizes, fitting is a breeze. I get a good seal with out having to really tighten the straps and it is comfortable. The only drawback is the way the upper straps are done. The Hans-Rudolph did not require a forehead support, so that is a little annoying with this mask.

  • This is the Holy Grail of CPAP Masks

    This mask is ingenious. I will never buy another style. Having 3 fit options is fantastic. I have a large face and the larger of the 3 options is perfect. No leaks = a good nights sleep.

  • Best mask time and again

    I have used the Flexifit 431 for most of the last 10 years or so. I have facial hair so it's been very hard finding any masks that keep a seal. I have tried numerous "new and improved" masks that have come on the market making all kinds of promises, but always come back to this one. Far and away, the best.

  • Perfect for me

    I've used a biPAP machine everytime I sleep for seven years. During that time, I've tried at least six styles of mask assemblies. This is the one that works best for me. I have fewer problems with escaped air around the mask. I am more comfortable with the mask grip around my chin. I sleep on my side most of the time and this style works well for that.

  • The best full-face

    Have tried several full face masks, but this is my third 431 and I love it. Once you get the adjustments set, you sleep without leaks.

  • Best Full Face Mask - No Leaking

    This is my third Fisher Paykel Model 431. I tried out a lot of full face masks when I had to change from nasal only to full, and this is the only model I found that didn't leak. I like the way it comes with multiple sized masks--as when one of mine tore, I just switched to another size without much difficulty. The only difference between this new one I just ordered and my old one, is that the new one makes more noise through the exhalation port than my old one. No idea why--they look identical.

  • Fantastic mask

    I am so happy with this mask. I have a Mirage Quattro which making an ongoing sore on my nose so I decided to order this as a second mask. It is fantastic. However, the first couple of nights I had a lot of trouble with the 431. It seemed like I had to tighten it so much that it really dug into my cheecks or it would leak near my eyes. I kept working with it, trying to loosen it a little at a time and finally got it where it is perfect for me. What I like best is that the bottom seal comes under the chin. I can move my mouth around and the seal doesn't come undone and leak. It is a terrific mask. I use REMzees with it and next time will not order the ones that go with the 431. I will be ordering the ones that fit the Mirage Quattro medium. They actually work better with this mask (small seal)for me than the ones that are supposed to fit it. They don't fit about an inch at the top of the chin but I still like them better. When I need a new mask, I will try the F&P 432 but this one is great.
