Product Reviews

The 3M 5P71 is a P95 oil-resistant particulate prefilter disc that snaps under the 501 retainer over a 3M gas cartridge to add particulate protection and extend cartridge life. This 3M 5P71 review covers what it does, which respirators it fits, and how it compares to the 5N11, 2091 and 2097 filters.

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.
