Guides

Acid gases — chlorine, hydrogen chloride, sulfur dioxide and chlorine dioxide — come from water treatment, chemical processing, battery rooms and acid-catalyzed coatings. This guide ranks the best 3M acid-gas cartridges, led by the 60923 OV/acid-gas/P100, with the gas-only 6003 and pure-acid 6002 as alternatives.

Spray painting throws two hazards at once — solvent vapor and atomized paint overspray. The best 3M cartridge for spray paint is the 60921 OV/P100, which handles both in one. This guide ranks it against the budget 6001, the 60923 for acid-catalyzed 2K coatings, and the right prefilter and mask pairings.

Spray painters working with two-component isocyanate coatings, pesticide applicators handling organophosphate concentrates, and lab technicians managing acid mist co-exposures all need the same protection class: organic vapor (OV) absorption, acid gas (AG) absorption, and a P100 particulate barrier…
