Dust Mask or Respirator While Grinding? - Beginners Place ...
Well worth it and has a better nose bridge fit and seal. They use the same filters. I have a small beard, but I can still get the mask to seal properly according to the seal tests listed with the mask. You can't go wrong with these for the price. I got mine off amazon for $24 and p100 (good for grinding) filters are very inexpensive.
