Respirator Cartridge Color Chart: NIOSH standardizes respirator cartridge colors under 42 CFR Part 84. Black = organic vapor. Magenta = P100 particulate. White = acid gas. Yellow = OV + acid gas. Green = ammonia. Olive = multi-gas. Brown = formaldehyde specialty. Blue = carbon monoxide.

How to Choose a Respirator Cartridge: Choosing the right respirator cartridge comes down to three steps: identify the hazard type (particulate, vapor, gas, or combination), match the NIOSH-approved cartridge class to that hazard, and confirm the cartridge fits your specific facepiece brand.

The Honeywell North N75001L is an organic vapor cartridge with no P100 particulate filter. The N75002L adds acid gas protection for organic acid environments. Neither cartridge includes P100 protection - they are analogous to the 3M 6001 and 6003.

The Honeywell North 7580P100, 7581P100L, 7582P100L, and 7583P100L form a cartridge hierarchy for the Honeywell North respirator platform.

The 3M 6001 is an organic vapor-only cartridge with no P100 particulate protection. The 3M 6003 adds acid gas coverage for OV plus organic acid environments. Neither cartridge includes a P100 filter - pair with 3M 2091 prefilters for combined particulate protection.

The 3M 60923 covers organic vapor, acid gas, and P100 particulates. The 3M 60926 adds hydrogen fluoride (HF) and chlorine dioxide protection - required for semiconductor fabrication, glass etching, and chemical plants handling fluorine compounds.

The 3M 60921 provides organic vapor plus P100 particulate protection. The 3M 60923 adds acid gas protection for HCl, SO2, and Cl2 - critical for chemical processing and industrial cleaning environments. This guide compares protection levels, NIOSH approvals, and job-specific selection.
