Honeywell North 7600 review: the premium silicone full-face respirator at APF 50 with built-in eye protection, taking the same North cartridges as the half masks. Who actually needs full-face, where it excels, comfort, cartridge fit, OSHA rules, and how it compares to the 5400, 7700, and 3M.
Honeywell North 5500 review: the budget TPE half mask that takes the same North cartridges as the 7700, so protection is identical for less. Who it suits, where it excels, comfort, cartridge compatibility, OSHA rules, and how it compares to the 7700 and 3M half masks.
The Honeywell North 7700 is the comfort benchmark among reusable silicone half-mask respirators. This research review covers who it's for, where it excels (painting, maintenance, silica, mold, welding), comfort, full North cartridge compatibility, OSHA requirements, and how it compares to the North 5500 and 3M half masks.
The 3M 2097 is a P100 bayonet particulate filter with added nuisance-level organic vapor relief for welding, cutting, and solvent-mist work. This review covers what it's used for, which 3M 6000, 6500QL, and 7500 respirators it fits, where it falls short, and how it compares to the 2091, 2297 and 2071.
The 3M 2096 is a P100 particulate filter with nuisance-level acid gas relief - for welding, foundry, plating and chemical work where fume meets low-level acid-gas odour below the OSHA PEL. This 3M 2096 review covers what it protects against, which respirators it fits, and how it compares to the 2091 and 2097.
The 3M 2091 is the standard P100 particulate filter: 99.97% oil-proof protection against dust, fume and mist, and the most-stocked P100 in the 3M bayonet line - particulate only, no gas relief. This 3M 2091 review covers what it protects against, which respirators it fits, and how it compares to the 2291 and 2097.
The 3M 2078 is a P95 bayonet particulate filter with added nuisance-level relief from acid gas and organic vapor odors. This review covers what it's used for, why nuisance relief is not gas protection, which 3M 6000, 6500QL, and 7500 respirators it fits, where it falls short, and how it compares to the 2071, 2097 and 2096.
