Czech M10 Gas Mask Filter dissection. Had to see for myself, how its constructed. I am making no scientific or legal claims, regarding wether or not these filters are safe to use. Still have no idea if its safe or not. And, I am not making any recommendations either way. If the black particles are activated charcoal, its probably not good to breath in. Also concerning is the very fragile, thick, white "toilet paper" like layer, just beneath the gauze layer.
