3M P100 Respirator Cartridge/Filter 60925, 1 Pair, NIOSH APPROVED, Protects Against Formaldehyde, Organic Vapors and Particulates, Use in General Manufacturing, Heavy Industrial, Metal Production

this unit is so good. It even keeps out harmful odors and fumes. great life saver.

I saw the possible need for these so I bought them early. I also bought a full 3M face mask. I use them when going to certain places. Yep most people think I look like a loon, but then you get people walking up asking where did you buy it from. If you want just about 100% safety these are great. Just remember they don't last forever. I think I read that you can get about 48 hours of breathing use if it's just plain air you are breathing in and not smoke or some kind of chemicals that clog the filters faster. So for Covid 19 I would assume that 48 hours is the max time between changing the two cartridges. Do your own research on it and remember it only works as well as the mask seals onto your face.

Tiny bit of a learning curve getting it attached, but you catch on quickly. Comfortable, easy to use, does the job while I’m doing stinky home projects.

Beware of buying the fake and cheap immitations from China. Order the genuine 3M cartridges from Amazon and avoid health issues.

The package and item was in perfect condition. This is a really good product for the price.100% recommend

Use these with my 3M 6000 series half mask when using my airless paint sprayer, in the attic or crawl

Installs easy, no smells whatsoever were able to penetrate the filters!

Yes this cartridge works great im a licensed embalmer and I got tired of breathing formaldehyde in all the time. Now I don't have to worry about thatm
