3M Organic Vapor Cartridges: For most industrial environments where organic vapors and particulates are both present, the 3M 60921 (OV + P100 combination cartridge) is the right default. It covers solvents, fuels, and coating vapors while the integrated P100 filters dust, mist, and aerosol.

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 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.
