    The obvious issue here is the p100 p/n 2097 filters are simply not available anywhere. Understandably so. I have a decent supply of N95's. Had them long before the coronavirus stuff broke. So I'm good for quite a while but I'd like to switch to a 3M 7000 series half face respirator. Is there a cartridge that might be readily available and would be safe to use in knifemaking? I'm not real hip on what works and what doesn't. I know the N95's are good and I assume the p100's are the standard? What else is better than good for the 3M 7000 series?

    Right now I can't find anything certified genuine that I'd trust , at any reasonable price .

    That will eventually resolve , but who knows when ?

    I’ve used a Moldex 8000 half face for 10 years or better. Gemplers shows a few kits in stock.

    I read the 2091 filters are good also. I was able to find the mask at regular price and paid a small up charge for the filters from another location.

    N95 captures 95 % of particles. p100 captures 99.8% according to the 3m website.

    Right now with almost no ability to buy in person, I'd be really careful of inferior knock off products that don't meet specs.

    I sure wouldn't be buying some generic clone universal fit cartridges off amazon.

    Genuine 3M or North cartridges from local genuine dealers in person if you can.

    There are three mask sizes, S M L

    Get the silicone mask, it's softer.

    I think they are different mounting systems, you pick one and stick with it.

    The typical P100 pancakes are the cheapest,

    but also look at the combo P100 and VOC cartridges - they have a little charcoal in that absorbs the acetone and glue solvents.

    3M 7000
    https://www.amazon.ca/3M-50051131070009-Particulate-Filter-2091/dp/B07571LKP4/



    North 7700


    https://www.honeywellsafety.com/Pro..._Series_Half_Mask_(North_Brand).aspx?site=/ca




    https://www.amazon.ca/North-7580P100-Particulate-Cartridge-Pairs/dp/B086Q2KTRR/
    https://www.amazon.ca/Honeywell-N750036-North-Filter-Covers/dp/B00RM4YI2/



    Those cartridges have snap on covers and prefilter elements that can be changed very very cheaply and stretch the life of the main cartridge.

    Get a package deal , especially now
    don't buy a mask without filters.

    Although I have no idea who has any instock.

    I have been able to find the 60926 and 60921 occasionally on Amazon. Few and far between though. Several people price gouging on eBay, but I'd be careful with those guys.

    I just jumped onto amazon and also see the P100 filters available. I think the real crush is for the N95 respirators .... and the P100's went first out of people panic buying .... but maybe look like they are starting to come back (with all the debate over wearing even cloth masks .... my guess is that very, very few people are going to want to wear a P100 respirator in public .....

    Slight aside - after the initial incredible run on hand sanitizer, I am starting to see it becoming available, and not selling out, at the local stores. Sure - locally produced by micro distillers per CDC guidelines - but it is not quickly being snapped up. Just offered up as more evidence that the P100 respirator cartridges may be becoming more and more available.

    BTW - still lots of counterfeit N95's and KN-95's out there - so be careful

    3M and Honeywell (North) have official stores on amazon.

    I might trust them, not third party resellers.

    Those would be the places to buy filters etc. There is a lot of fake & inferior PPE stuff out there now.

    Yes
    Maybe I'm out of touch, or our currency exchange is just crap, but $40 for a set of filters seems way too high.

    How much are your lungs worth?

    I think it's pandemic gouging.

    I paid less than that for the half mask respirator with filters.

    Or it is basic supply vs demand pricing. Though granted, there is a grey line between that versus gouging. It really does come down to how much you think your lungs are worth...

    I've found a few in the $25 - $29 dollar range and um going to get them ordered. I feel like the 3m N95 just isn't cutting it. I also have a HEPA air shop filter coming to help out too.

    i have found the acid filter load up far too fast (got a set by mistake) the 95s with the pre filter are the way to go wash out the pre filter now and then really helps the canisters last longer

    The cartridges are fine as long as they are p100. I used the P100 OV for a while as I had some painting to do also. Got some 2097 for next change. The cartridges always give me dry mouth for some reason. Hopefully the 2097 don't do the same thing.

    Just ordered a couple of respirators from uline.com for a home fiberglass project.

    Most of their 3M products are reorders only as in previously ordered while their north products are not.
