3MPerformance P100 Particulate + Odor Filters, 2 pairs, NIOSH-APPROVED P100, 99.97% Filtration Efficiency Against Solids & Liquid Aerosols, For Use With 3M 6000, 6500 & 7500 Series (2097P2-DC)

They're not just super light weight, their the best in the business. I'm a metal worker who likes to always be well protected when I'm grinding metal. Essentially nothing of consequence gets through these. Once you make the switch to these filters, you probably won't want to use anything else ever again. They completely humiliate competing products from even the most reputable welding companies in the world. I know this from direct experience welding and grinding metal. My nose, knows. 3M's own 2297 filters are supposed to be more advanced, but though they are easier to breath through, they don't filter as well when the air gets really filthy. Also, beware of the many knockoff, fake 2097 filters that pretend to be P100 but have no NOISH approval. They look very similar and will fit 3M's masks but they are useless garbage when it comes to actual filtration. They are basically a scam.

Not only do these filter the air as our employees work, it give them peace of mind that we care enough to supply them.

I used it to apply polyurethane on some cabinets and could not smell anything

Use them all the time. Only ones my husband uses

P100 protection level. Works for dust removal, sanding, grinding and welding. They are real 3M products. I wouldn't trust a cheap filter to protect my lungs. They even remove some smells.

This was bought for various reasons including the intended use. I could use the typical cheap paper mask filters, but I prefer these high quality filters. I could get those other masks with NIOSH ratings of N95, N99, P99, but the P100 is the best and work the best. These also work great with the masks and quickly attach/de-attach.While they do a good job of blocking some smells, after a while they begin to smell odd themselves so replacing frequently is a must if that bothers you.

These are genuine 3M P100 2097 filters. I received 2 pairs in the box (4 filters total). Each pair are individually sealed. After reading a few reviews I wasn’t sure exactly how many to expect. I purchased these early September 2024. The USE BY date is stamped 06/2027, which is great!

I'm using these with a 3M #7503 half face-piece respirator while doing a retro-fit of my attic insulation. 40-year-old loose-fill fiberglass infested with squirrel and chipmunk droppings, sunflower husks, acorn remnants etc.I feel much safer using a well-fitting respirator with replaceable filters instead of the various rubberband-style masks. Bought the 2-pair pack for economy but you can also buy a single pair -- fyi, there are lots more Amazon reviews on this filter under the single-pair item.There is a lot of info on filters and govt-jargon from OSHA & NIOSH that can overwhelm a non-expert like me. Someone on the single-pair product page gave these filters a 1 star review which I thought was unwarranted. So after some research, here is some of what I posted there, hope it helps you make the right choice...The "P" doesn't refer to particulate, it means the filter media is strongly-resistant to oil ("oil-Proof"). The other types are R for oil-Resistant and N for Not.Regarding size, particulate filters remove very, very small particles: smaller than 0.3 microns in diameter and that is just the median size of the particles in the test. For comparison, smoke has particles about 2 microns in diameter."100" means the filter is removing 99.97% of the particles. Compare that to filter types of, say, N99 and N95 which remove 99% and 95%, respectively. But all three types remove the vast majority of very, very small particles; 100-type filters remove the most over the duration of the test.This filter gives "relief against nuisance levels of organic vapors". But it's not for use in high concentrations.And while a filter like this will filter smoke particles, there are also gases in smoke -- DON'T breathe exhaust gases -- if there is CO it can kill you!Finally, I don't weld but per 3M's instruction sheet these can be used to filter "metal fumes produced from welding, brazing, cutting and other operations involving heating of metals."Peace out!
