Gas/vapor filters consisting of small cartridges containing substances (e.g., copper-silver-zinc-molybdenum-triethylenediamine, ASZM-TEDA) that can absorb and/or destroy chemical (e.g., cyanogens chloride, phosgene, sarin) agents in gaseous or aerosol form from the air as they pass through. These cartridge filters are disposable devices intended for protection against a limited number of exposures to contaminating agents. Chemical agent protection cartridges are used in respirators and masks to prevent the chemical agent from reaching the respiratory mucosa, the eyes, and the face of the user.
