Use one cartridge to replace multiple chemical cartridges
Cartridges protect against organic vapors (paint/pesticide); ammonia (anhydrous or from livestock confinement) and methylamine; acid gases (disinfecting livestock, chlorine, sulphur dioxide and hydrogen chloride). Pre-filters and retainers sold separately based on specific application needs. NIOSH approved; TC-23C-1809. Box of 10. USA made.
NOTE: A Smart® cartridge will last a shorter time when protecting against a single hazard like a pesticide.
