14PCS (7Pack) 2091 P-100 Particulate Filter, Installed on Filter Retainer Replacement Cotton for 6000 6200 6800 7000 FF-4 Series Respirator Mask,Use for Against Dust,Torch Cutting,Chemicals

Needed replacement filter for a mask I got in 2018 off Amazon. got these and they work very well. I used them for sanding, concrete mixing, cleaning, even sitting around a campfire and they keep the fine particles out. I think they are supposed to be good for lead and dust, but don't quote me on that.I have used them when around any kind of mold situation, and although I don't know if it was made for that, but it does make the air smell better. I thin k they work pretty good and the amount I paid for how many I got was a good deal. I even wore this mask/filter combo during the pandemic, and store employees would always comment "great mask!".I assume they meant it and were not being sarcastic, LOL.

Works like a charm. Keeps my lungs and nasal clear. I weld and it's hard on the lungs and stuffs your nasal cavity but not with this respirator on.. it does get sweaty but taking breaks Keeps that in check.

So I’m not 100-% sure if this is some sort of American brainwashing on my part but for some reason having no brand name on these bugged me? These are decent filters, and I use them all the time in my garage machine shop.. I probably wouldn’t bet my life on these filters but honestly if you just need something more than a dust mask can handle these are fantastic! Customer service is amazing too so if you have a problem don’t hesitate to reach out.

I like'em good quality for a good price and, I use these filters for welding and it fits under the hood

Good quality particulate filters. Fits my 3M unit perfectly

Since I'm in quarantine due to low defenses, this have been my go-to first line of defense against airborne viruses and bacteria, at least until my immune system is up and running 100% again.

Fit my mask well. Great price.

"Like most woodworkers, it's always been a pain to wear suitable breathing apparatus. This product is by far the lightest and least cumbersome I've ever owned. While you know you have a mask on, it feels like I'm breathing fresh, cool, clean air. It's very light and easy to snap on. I was afraid I would go through lots of filters, but I don’t wear it for eight hours a day, and yet I've yet to have to change the filters since I started using it two months ago."
