COMPATIBILITY: The FlexiFit 431 uses only the Silicone Seal while the Forma and FlexiFit 432 masks use both a Foam Cushion and Silicone Seal. If you are using a Forma or FlexiFit 432 mask and would like to purchase a cushion and seal set, those can be found elsewhere on this site.
SIZING: The FlexiFit 431, FlexiFit 432, and Forma each use a single frame for all sizes; therefore, if you would like to change the size of your mask, you just need to purchase a different seal (or cushion and seal) size.

My old facemask seal was about 3 years old. New seal beings fresh life to breathing Written by Verified Shopper, 2014-03-30
Fits great! Written by Steve C, 2014-03-20
.Best Comfort and Fit
The mask is shaped to tuck comfortably "under" the chin, without putting pressure on my lower teeth. It is much lighter in weight than other full face masks I have tried. The nose bridge fits better and without skin irritation. This is the best mask I have tried, and the most comfortable. Would highly recommend it to others. Written by Verified Shopper, 2013-09-15
