Chemical cartridge

<p>A <a href="/facts/Respirator/rYFJThhR">respirator</a> cartridge or <a href="/facts/Gas_mask/1I8Y1wSs">gas mask</a> canister is a type of filter that removes gases, <a href="/facts/Volatile_organic_compound/BFMlKwgt">volatile organic compounds</a> (VOCs), and other vapors from the air through <a href="/facts/Adsorption/ARH9peYM">adsorption</a>, <a href="/facts/Absorption_(chemistry)/XGeB64bC">absorption</a>, or <a href="/facts/Chemisorption/QW4hL1RR">chemisorption</a>. It is one of two basic types of filters used by <a href="/facts/Air-purifying_respirator/rYFJThhR">air-purifying respirators</a>. The other is a <a href="/facts/Mechanical_filter_respirator/fjx2PG5y">mechanical filter</a>, which removes only <a href="/facts/Particulates/RleGr5E6">particulates</a>. Hybrid filters combine the two.
</p><p><a href="/facts/Workplace/RCIrBH8J">Workplace</a> air that is polluted with fine <a href="/facts/Particulate_matter/RleGr5E6">particulate matter</a> or noxious gases but that contains enough oxygen (in the US, this is ruled to be a concentration above 19.5%; in the Russian Federation, above 18%), can be rendered safe via air-purifying respirators. Cartridges are of different types, and must be chosen correctly and replaced on an appropriate schedule.
