3M Multi Gas/Vapor Cartridge/Filter 60926, P100 Respiratory Protection (Pack of 2)

Very effective filter! Very few odors come through.

No hay mucho que decir, estos cartuchos se adaptan a mis necesidades de trabajo y 3M es de las mejores marcas. Recomiendo leer la hoja del fabricante para determinar cuáles cartuchos necesitas y para determinar con cuánta frecuencia reemplazarlos.

Funcionan a pesar de que casi los rompo al intentar ajustarlos al respirador.

I've been using these filters for about 8 years now and they filter out just about everything gases organic matter spray paints welding gases and you do not smell anything when you're wearing these filters on your mask

I'll be frank. About 3 months ago, noxious fumes started entering my apartment, and everything about them (smells, residue, symptoms) are consistent with a meth lab. I've talked to apartment management and law enforcement, but all I got was a nasty letter from the apartment management's lawyer telling me that I couldn't hire a contractor to test for what I was being exposed to without their permission. My attorney told me to stop living there, and to move my things out ASAP, and due to the health effects of the fumes (heart palpitations, chest pains, burning eyes and verifiable eye damage consistent with meth labs, burning throat, nosebleeds, dizziness, confusion, numbness of my face, etc.) I started to wear a respirator when I entered the building to retrieve my stuff. At first I used the magenta/yellow filters that came with the respirator, but the symptoms were only slightly better, and I couldn't spend much time in the apartment without becoming so dizzy that I actually fell over once and hurt my wrist. After some research on Amazon, I found these magenta/olive filters, and they help much more than the magenta/yellow. With the magenta/olive filters, I do get the feeling my legs are going to collapse under me when I first enter the apartment (probably from ether, the same thing that would cause numbness -- and no little filter like this could take all of it out of the air), and I get a slight taste of pretzels on my tongue, with a chemical taste to my tongue after exit the building and taking the respirator off, but it takes about 2 hours now for some of the bad symptoms like dizziness to start, so these filters give me at least some time to work on moving out. And today when I took off my respirator, I could smell the toluene odor on my hair or clothes, so I know it was still present in my apartment, but these filters must have blocked its smell for me (think that toluene smells like pretzels through these filters). Today I finally smelled formaldehyde when using the respirator, and I'd used the same filters for maybe 4 days, a couple of hours at a time, so my best guess is that they last about 8 hours. I have an extra set to switch out now, and ordered more today.
