The purple\/magenta color band is the NIOSH-mandated identifier for HE (HEPA-equivalent, ≥99.97% filter efficiency) particulate protection, providing SP3-level filtration against fine dusts, fumes, metal particulate, asbestos, and other hazardous aerosols. The cartridge features a bayonet-style twist-lock inlet connection compatible with 3M Powerflow blower units and carries NSN 4240-01-323-3526, confirming mil\/government procurement qualification. A factory-installed inlet sealing cap (pull-tab style) is visible in the photos, confirming the unit is new and unused with the filter media sealed. Manufactured in Canada (visible on label: \"Made in Canada \/ Fabriqué au Canada\"), this filter is sold as a single cartridge and is a direct replacement for use in industrial, pharmaceutical, nuclear, and abatement environments requiring maximum particulate protection.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
