Gas/vapor air filters designed to remove chemical agents from the air stream. These filters use gas sorbents according to the expected agent (e.g., nerve, blister) and the prevalent conditions (e.g., contaminant concentration, molecular weight and size, temperature); currently copper-silver-zinc-molybdenum-triethylenediamine (ASZM-TEDA) is considered the most appropriate sorbent for chemical agents. Chemical agent gas/vapor filters are used in air cleaning systems designed for permanent facilities and/or temporary emergency shelters.
