It is highly designed to meet heat and flame resistance. The 7000 or 9000 series of reusable respirators use this filter disc for all day comfort. Moreover, you can simply use this filter disc with nuisance organic vapors. This respirator filter is encased in plastic to provide durability for long lasting use.
