The masks are great, I have already bought the 5th package, as we had a large construction site with mold in the walls The masks sit super, close to the nose (whether large or small nose) very well and also the bottom of the chin it a good seal. Often one has in cheap masks after the dirt left and right on the nose, where it has not sealed properly, here is through the internal foam is not the case, which also ensures that the mask despite tight concerns not turning a blind nose. One can very well continue to breathe, the back pressure through the mask is surprisingly low. I'm going to buy anything else, whether I need this high FFP in accompanying working or not, I'd rather spend some more money on a mask, as I afterwards for days have the dirt in the nose.
