The 3M 2091 is a NIOSH-approved P100 particulate filter that fits the entire 3M 6000 and 7000 series half and full face respirators. After testing it across woodworking, drywall sanding, and asbestos abatement, here is everything you need to know.
Verdict: 4.7/5. The 3M 60926 is the broadest-spectrum combo cartridge — multi-gas plus P100 particulate in one. The procurement-flexible default for mixed-hazard work.
Verdict: 4.5/5. The 3M 60925 combines P100 + formaldehyde + organic vapor — covers histopathology lab chemistry in one cartridge.
Verdict: 4.4/5. The 3M 60924 combines P100 particulate filtration with ammonia and methylamine protection — refrigeration plants, agriculture, NH₃ chemistry.
Verdict: 4.7/5. The 3M 60923 is the workhorse combo cartridge — OV + acid gas + P100 particulate in one piece. The default for mixed-chemical work with particulate.
Verdict: 4.3/5. The 3M 60922 combines P100 particulate filtration with acid gas protection — niche but excellent for documented AG-only exposure with particulate
4.7/5. The 3M 60921 P100 Organic Vapor Combo Cartridge is the standard single-cartridge solution for spray painting — P100 particulate plus organic vapor protection in one piece.
