3M 2091 P100 Bayonet Filter Magenta PK2

The 3M 2091 is a P100-rated filter cartridge built for 3M half and full-face respirators. It targets industry professionals who need reliable particulate protection during assembly, mechanical work, painting or pesticide application. The magenta colour code identifies the filter class at a glance. Each pack contains two cartridges for immediate replacement or spares.

NIOSH P100 rating filters at least 99.97%

This single specification decides whether the cartridge matches the hazard. The NIOSH P100 certification confirms at least 99.97% filtration efficiency against solid and liquid aerosols including dust, fumes and mists. It does not protect against gases or vapours, so buyers needing organic vapour or acid gas protection must select a different cartridge type.

The bayonet mount aligns and locks with a quarter turn, so installation takes seconds without tools. A common error is twisting the cartridge onto an incompatible facepiece or failing to seat it fully, which breaks the seal. Users should perform a fit check each time the respirator is donned to confirm no leakage around the edges.
