Frequently Asked Questions

What is the difference between a P95 and a P100 filter in this range?

Both are oil-proof particulate filters, but they differ in efficiency. P95 filters like the 3M 2071 capture at least 95 percent of airborne particles, while P100 filters like the 3M 2091 capture at least 99.97 percent, the same as HEPA, and are color-coded magenta. Choose P100 for higher-hazard particulates such as lead or asbestos abatement.

What do the nuisance acid gas and nuisance organic vapor labels mean on filters like the 2096 and 2097?

Filters such as the 2096 (nuisance acid gas) and 2097 (nuisance organic vapor) are P100 particulate filters with a thin carbon layer for nuisance-level odors only. Nuisance relief is below the OSHA permissible exposure limit and is not a substitute for a proper gas/vapor cartridge when concentrations exceed those limits.

Do I need the 501 retainer with these filters?

It depends on the filter. The 2091, 2096, 2097, and 2291 series P100 filters attach directly to 3M bayonet respirators with no retainer. The 5N11 and 5P71 pre-filter discs, however, require the 501 retainer cap to hold them onto a cartridge. Never assume a retainer is needed for the bayonet-mount filters.

Are these NIOSH approved and what respirators do they fit?

These 3M filters carry NIOSH 42 CFR Part 84 approval and use the 3M bayonet connection, fitting reusable facepieces such as the 6000 and 7500 series. Approval applies to the complete assembly, so check the NIOSH approval (TC) label for the specific facepiece-and-filter combination you plan to use.

When should particulate filters be replaced?

Replace particulate filters when breathing resistance increases noticeably, when they become damaged, soiled, or wet, or at the end of a shift per your program. Unlike gas/vapor cartridges, particulate filters do not have odor breakthrough; resistance is the cue. Pre-filters extend the life of more costly cartridges by capturing coarse debris first.
