3/2/2024 0 Comments Expired gas mask filtersFor those, I went with #2097 filters, partly for their rating and partly because they are still showing "in stock" at my local Home Depot and between online and local purchase I want to make sure I can build a decent inventory.Īnyway, I saw that there were also quite a few 2091 P100 filters and they were slightly cheaper. I was looking at, and purchased, 6000 series 3M full face. However, it looks like care should be used in which you choose as there are a few different model numbers of P100 with different capabilities. Of the filters available for half and full masks there are still P100's out there. From what I see each step up in masks from N95 to half mask (with goggles) to full face mask seems to increase protection. There still seems to be decent availability of more pricey options like 3M (and other brands) half and full face masks and filters. I was looking at what's still available, mask/filter-wise last night on Amazon and other places.Īs has been noted, N95 masks have evaporated. Apologies in advance to the OP if not and moving to a more appropriate thread would be welcomed (there are so many CV threads I wasn't sure where to put it). This seems like an appropriate place to post this. ![]() But, in a pinch, they may work for particulate threats. There’s no way to know if or at what point any of the above could occur so it’s always best to avoid using expired filters. There is also the possibility that the material that provides the particulate filtration could age/degrade/collapse and allow contaminants to bypass the filter. The problem you can run into with expired filters is if the filter materials absorb moisture or if the catalytic materials required to filter/neutralize rated chemicals age or degrade, the filter is no longer useful for chemical threats. However, that said, provided the filter media is intact and hasn’t collapsed or degraded, an expired filter that was capable of filtering particulate threats before it expired, should still be able to do so after expiration. So my primary recommendation is, don’t use expired filters. ![]() The expired filter question is a hard one to answer because I don’t want to take responsibility for the QC of all filter manufacturers nor do I want to take responsibility for unwise users who try to push their luck with possibly degraded filters. It’s a little overkill, but most 40mm filters will be. It’s listed as a particulate filter as well. Thanks in advance for any advice and input! Anyone have the lowdown on this? I'm HOPING I don't have to get one of the $400 CBRN facemasks I see advertised everywhere to be safe! I've got regular N95 and N100 face filters, but those aren't full face solutions and I got to thinking. I'm doing a lot of reading on this since the latest 'hoo-hah' virus from China has hit the news as it kind of exposed a hole in my planning. So would a facemask and filter combination like that linked below be sufficient? I assume I'd need to get some N100 cartridge filters that they sell for this mask to be as protected as possible, or does what it comes with seem adequate for viral hazards? Sorry again, I just know what I don't know. Still not 100% certain of course, but at least a good component. but it seems to me that for real blocking of epidemic type threats, one needs a full face mask and filter combo. What would be the minimum filters stop viruses and what filters are the best to stop, well, everything like radioactive fallout particles to military grade bio/chem weapons? I also have a couple 3M 6000 series masks I might want to pick up some filters for. Thank you so much for some help understanding what I need or should get. I got it in a trade and don't know all that much about this stuff. I think I have some parts with the mask to convert it to side filters or something. What filters would be effective against, at minimum, viruses? What is the difference from the FR-57 filter?Ĭan't this mask also be fitted with 6000 series side filters like the 6003 filters my half face masks use? Should I just get more FR-64 filters or what else is available? ![]() I would like to buy new filter(s) because the one I have I have used in a lot of dusty work situations and it is probably clogged or whatever. I have a 3M 7800S mask and it is currently fitted with a FR-64 filter.
