A research-grade comparison of the 3M 6003 organic vapor/acid gas cartridge and the 3M 6006 multi-gas cartridge. Both cover organic vapor and acid gases; only the 6006 adds ammonia, methylamine and formaldehyde. We cover chlorine, acid gas, ammonia and formaldehyde, when to upgrade, compatibility, service life and value.

A research-grade comparison of the 3M 6001 organic vapor cartridge and the 3M 6006 multi-gas/vapor cartridge. The 6001 covers organic vapor only; the 6006 adds chlorine, acid gases, ammonia and more. We cover paint and solvents, chlorine, formaldehyde, wastewater treatment and when to upgrade from a standard OV cartridge to multi-gas.

Organic vapor cartridge vs multi-gas cartridge, explained: an OV cartridge covers solvent vapors only; a multi-gas cartridge adds acid gas, ammonia, and formaldehyde.
