P100 Respirator Cartridge/Filter 60926, 1 Pair, NIOSH, Helps Protect Against Organic Vapors, Acid Gases, Ammonia Methylamine, Formaldehyde and Particulates

Very effective filter! Very few odors come through.

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.

Good price. I didn’t die of black lung do it Worked well.

Throughout my life I've generally treated my lungs like crap and I'm ashamed to admit that I still smoke. I'm sure to non smokers the idea of a filter may seem like a waste of time but likely due to my smoking I've found my breathing more sensitive to other activities as well. I'm a mechanic by trade but also have the tendency to take on any task I need competed in life on my own. Both my work and that tendency likely expose me to many things that I shouldn't be breathing. Since purchasing a mask and some of these filters I've tried to make myself use them whenever I find myself approaching a situation that seems risky or any that have irritated my breathing in the past. I'm unaware if these filters are built to handle all of the crap I put myself through, but I have noticed that every time I use them I don't find myself suffering even worse breathing like used to occur at times. Things like burning brush, cleaning foam air filters or chains (use strong cleaner that chokes me up bad), grinding, and swinging a stick like a samurai while fighting hanging insulation in a damp, foggy crawlspace never seem all that bothersome anymore. They even block the smells. Just got back from that terrible crawlspace a minute ago and came here just to brag about how well these worked. I'll admit that the filters require more effort to breathe through than what natural breathing requires, but I've not noticed any desire to yawn, gulp, or hyperventilate even after 30 minutes to an hour in the mask during moderate physical activity. I feel like these are a great general purpose filter for people who may find themselves doing many random tasks. Certainly feels a lot better afterwards. Now if I can just drop cigarettes again I'll be set.

very good

Successfully Filters TRICHOTHECENES. This review may sound like Chinese to many of you (at least until there is more of a public awakening about this crisis). But I want to reach those that will understand the relevance, as it may help you know what to choose. I didn't even need the 60928 filter model. The "professionals" needed three tries to finally successfully remediate my house for mold in 2012. They promised that the indoor air quality (IAQ) in my house was then pristine-- based on follow-up 5-minute air-sample mold testing (which is beyond the scope of this review, but is a complete farce in and of itself). However, they forget (or were too clueless) to tell me about one MINOR issue (facetiousness intended)-- that even the best enzyme-based bioremediation products on the market do ABSOLUTELY NOTHING for the residual TRICHOTHECENES in your carpet, on your linens and clothes and furniture, etc. Trichothecene poisoning has led to my toxic encephalopathy, polyendocrinopathy, hypogammglobulinemia, etc etc, and MCS / Toxicant Induced Loss of Tolerance (TILT) / Gulf war syndrome-type syndrome (GWSTS). I'm not whining, simply elaborating enough so that you know that I'm extremely familiar with human mycotoxicosis, and especially the hypersensitive phase of Trichothecene mycotoxicosis. With that preamble-- and due to the incompetence and/or dispassion and/or callousness and/or fear of the men that promised me a clean and healthy IAQ in my house-- I've been left to fend for myself with the Trichothecene contaminated carpet. It took me many months of remaining sick despite agressive therapies to figure out that something was still awry in my house. I finally narrowed it down to the carpet-- and sent samples to an independent lab in March 2014. Trichothecenes were 22.3ppb (translation = 111.5 times above the government-set toxic human threshold). Would have been swell to know this 2 years ago........ Might not still be out of a job and in bed an average of 18+hours/day. So, after requesting carpet removal help from the aforementioned crew-- which by the way are some of the "nations leading mold remediation experts" from both the East and West coasts-- and now 3 months and still waiting for them to squeeze me into their schedules-- TO FINISH AN INCOMPLETED 2-year OLD JOB-- my 71 year old parents and myself have decided that its not gonna get done, and get done right, unless we do it ourselves. I figure that with my health, the project will take about 6 months....... But if its the carpet that is keeping me sick, what other choice is there. Sooooooo---- over past few weeks, I've spent couple partial days taking every precaution, wearing a Tychem suit, a 3M 6900 mask with two 60926 canisters....... Creating plastic vapor barriers to contain the disturbed microbial VOC's......And pulling HIGHLY CONTAMINATED carpet that is filled with dust-bound and free-floating Trichothecene VOC biowarfare neurotoxins. A transient single whiff of Tricho's used to put me in bed with flu-like symptoms for weeks at a time. And while the energy required to perform the current task is challenging due to baseline symptoms, I have NOT experienced any signs or symptoms of EXOGENOUS re-exposure while wearing the 6900 with 60926 canisters. So, I highly recommend them for anyone wondering/needing something to filter macrocyclic sesquiterpene Trichothecenes (a product of Stachybotyrs, Fusarium, Trichoderma molds which can be found in homes with visible OR INAPPARENT water-damage issues). Be safe.
