The 3M™ Particulate Filter 2091 is NIOSH-approved P100, providing at least 99.97% filtration efficiency against oil and non-oil based aerosols, dust, mists, fumes, and particulates. Color-coded magenta per NIOSH P100 standards. Uses a bayonet-style connection compatible with 3M™ 6000, 6500, and 7500 series facepieces. Filter material is polypropylene with electret media for low breathing resistance. Sold as a 1-pair (2 filters) pack. Common applications include mold remediation, lead paint removal, woodworking, fiberglass installation, welding, and asbestos abatement. The 2091 can also be stacked with a 6000 series gas cartridge to add both particulate and vapor protection. For workplace and occupational use only.
What is the difference between the 3M 2091 P100 filter and the 2097?
Both the 2091 and 2097 are P100 particulate filters with the same 99.97% filtration efficiency. The 2097 adds nuisance-level organic vapor relief, meaning it contains some activated carbon to reduce odors and nuisance-level OV concentrations. The 2091 is particulate-only. If you only need particle protection, use the 2091; if you want some odor reduction alongside particle filtration, use the 2097.
Does the 3M 2091 protect against gases and vapors?
No. The 2091 is a particulate-only filter rated P100. It does not protect against organic vapors, acid gases, or other gaseous hazards. For combined vapor and particulate protection, pair the 2091 with a 6000 series gas/vapor cartridge (such as the 6001) — the prefilter attaches in front of the cartridge — or use a combination cartridge like the 60921 or 60923.
Which respirators is the 3M 2091 compatible with?
The 2091 is approved for use with 3M™ 6000 series half and full facepieces, 6500 series, and 7500 series facepieces. It also fits the FF-400 series and 7800S series facepieces with bayonet connections. Note: the 2091 is not designed for use with 3M 5000 series respirators — use the 5P71 prefilter for those.
Can I use the 2091 for mold remediation and asbestos work?
Yes. The P100 rating on the 2091 exceeds the requirements for mold remediation (which calls for at least N95) and meets the OSHA standard for asbestos abatement that requires at least P100. It is also appropriate for lead paint removal, fiberglass work, and silica dust exposure. Always follow applicable OSHA standards and use a properly fit-tested respirator.
When should I replace the 2091 particulate filter?
Replace the 2091 when it becomes difficult to breathe through, visibly soiled or damaged, or after any use in environments where it may have been contaminated with toxic particulates. Unlike gas cartridges, P100 filters do not lose efficiency from use alone — they can actually become more efficient as some particulate loads build up — but increased breathing resistance indicates it is time to replace.
Is the 3M 2091 the same as the 7093?
Both are 3M bayonet P100 particulate filters, but they differ in design. The 2091 is a flat disc filter intended for the 6000/6500/7500 series half-facepieces and is typically used as a standalone filter or layered with a cartridge. The 7093 is encased in a hard plastic housing designed specifically for 3M™ 7000 series full-facepieces and other environments requiring protection from debris, sparks, and decontamination showers. They are not directly interchangeable in practice.
