I can't smell anything when wearing these. As soon as I take them off, I realize the outdoors smells very nice.

As advertised and well delivered.

As described

Works well in ammonia

These filter cartridges are super easy to install and replace, which I really appreciate—no complicated steps or tools needed. They fit snugly into the mask and feel secure during use. That said, the one downside is it's hard to tell how well they’re actually filtering. There’s no visual indicator or clear way to measure performance over time, so I mostly have to trust they’re doing their job. Overall, convenient and user-friendly, but I’d love more transparency or reassurance about effectiveness.

I just realized the filters are not expired, turns out the date on the filter that says 2023 is the production date not the expiration date. The expiration date is on the outside of the package right side bottom.

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.

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.
