Our take
These pink discs turn a 3M half facepiece into a P100 respirator, the highest particle rating NIOSH gives. Against the PM2.5 in smog, that's as good as filtration gets.
They last until breathing through them gets noticeably harder, or they're damaged or dirty.
Good for
- Pairing with the 3M 6502 half facepiece
- Heavy smog and smoke
Skip it if
- You want help with smells too: the 2097 adds a carbon layer

How we judge. We haven't tested the 2091 P100 particulate filters (2 pairs) in a lab of our own. The figures come from independent ratings (AHAM, Energy Star, NIOSH, the ASPCA) or the maker, and the verdict is ours, from those figures. No brand pays to be listed. Last checked Nov 7, 2026.
