About this product
The 3M 2138 P3 Dust/Mist/Nuisance Level Ov/Ag Disk Filter is a particulate filter for respirator work where the dust is genuinely nasty, not just annoying. The P3 rating covers toxic particulates, which is why it gets pulled out for jobs like mould remediation. It also handles nuisance level organic vapours and nuisance level acid gases, so you get some relief from odours on top of the particulate protection.
Think of it as a particulate filter first. It is rated for low vapour pressure organic vapours in the GP2 sense, but the vapour and acid gas side is nuisance level only, not a substitute for a proper gas cartridge where concentrations are real. Fit them to your matching 3M facepiece, check the seal before you start, and swap them out once breathing gets harder or you can smell what you are filtering.
