    You guys say everything is bigger in Texas, looks like the air is dirtier, too. All kidding aside, sometimes you just don't realize what's in the air when you weld, cut, grind, etc.......those filters make it look like I'm safer smoking a couple of packs a day!

    Lol, I use my respirator when I'm doing other stuff too like cutting the grass, blowing the leaves, axe'ing bbq firewood, chainsaw'ing bbq firewood, miter saw'ing bbq firewood, etc. Those filters got their fair share of just plain ol' dust and dirt from a bunch of activities.

    Is all of that nastiness or is some of it carbon filtration? I'd rip a new one open to look but don't have enough right now to part with one.

    Pretty sure it's part of the carbon trap element. I thought it might have been metal grit but it would have gotten stuck on the first filter layer.

    3M™ Gas & Vapor Cartridges
    These cartridges utilize sorbent material to filter the gas or vapor
    molecules. Typically the sorbent is activated carbon. Different
    chemical treatments may also be added to the surface of the
    activated carbon to adsorb different types of gases or vapors. When
    the cartridges reach their capacity, the gases or vapors start to come
    through the cartridge to the user. This is called “breakthrough.”

    At work we use the 3M 6000 series half face with the 2097 cartridge when handling pure caffeine to make energy drinks. The 2097 looks similar except for its bright magenta. They are really good for quick spray paint, and small solvent cleaning jobs. I haven't used these for welding , I have a disposable welding mask that I have used for a while now. I think people underestimate how much the respirators save you lungs.

    Oh ok, sounds good. Previously I have heard people tell me that since I use Google to host pictures, and some people's computers don't like that until their cache is cleared.

    I was on my ipad when I first looked and did not see them. Then I was on my phone and they show up just fine. Now I’m back on the ipad and no go again. I don’t want to clear the cache so it’s no biggy. Pretty dirty filters.

    I've done that, too, before I got my fresh air hood. Nasty stuff in that smoke. What kind of welding are you doing?

    Mostly MIG/dual shield/stick as of late.

    That dual shield puts out a lot of smoke. I see these guys where I work not using any kind of protection and just have to shake my head.

    I seem to have a hard time breathing anymore if I don't wear a respirator while I'm welding. I ve been doing a lot of stick, fluxcore self shielding and some mig thrown in.

    Yeah, those respirators are great. We had to spray paint some nasty automotive stuff the other day and the respirators worked great!

    Re: the anatomy of a used 3M 2297 pancake respirator filter

    Understand Im not bragging so don't get it the wrong way. Ive never used respirators, as a matter of fact growing up workin with the old boy me and my Dad never used much of any PPE, cutting timber and workin in the old bootleg coal mines. I suppose its just the way I grew up. We had somewhat of a mentality that there was other stuff we could do for a living if we was really concerned about health and safety, in other words just drive on and get it done. 45-50 years later I wish I had took better care of myself and absolutely never would have started smokin 2 dsys after getting out of diapers.

    So I get out in the real world and go to work in a big coal mine with about 30 fellas on a shift, they give me a MSA dustfoe respirator, just a little thing but supposed to be very effective for what it designed to do. I cant stand the damn thing on my face, same crap I dealt in the Army...hyperventilating within about 20 minutes of putting the thing on. I guess its just something in my head I never learned to deal with...like a fear of closed places, or water, heights or something like that.


    Well here I am 61 years old and they tell me I got COPD and well on my way to emphysema and black lung and still workin and welding out in any kind of weather evry day. I refuse to give up, I got it in my head that I done it to myself and so just deal with whatever comes at me like Ive always done. I'll most likely die out there in the strippins doin what I do. Im still having fun doin this work but Id really like to say to any young folks deciding to do any kind of work involving dust fumes or whatever use the respirator and give up smoking if you do it...maybe when you are 61 years old you wont be coughing up a quart of snot evry morning before you go to work.

    Oscar, how long were those in use? If that's 8-10 hours worth yea that's pretty dirty for that period of time. If they are days or weeks old it may not be that bad. We have to time and date ours and change every 8 hours. Better not get caught with a cartridge over 8 hours on your mask.

    Oscar, I'm also a very firm believer of:

    Safety glasses
    Half mask respirator
    Ear plugs
    (or my AM radio muffs so I can work and listen to my conservative radio and curse out in my head the latest libtard nonsense)

    I use 2097 pink filters, also covers you from some ozone in addition to the oil and non oil stuff 2291 filters catch
    (we generate lots of ozone when arc welding...)

    These were used for months, but not months like your months, these are Oscar-months, lol. I installed those back in October. But I'm not a weldor. I'm a hobbyist, so I can't break it down like X hours per day, Y days per week, Z weeks a month kind-of-thing. I'll go weeks without lighting up any kind of welding electrode at times. Most of that crud is from chainsaw'ing/miter sawing bbq firewood, cutting the grass/weeds, blowing the leaves with the gas leafblower, basic household things like that. I'd say only about 30-40% of that crud was from working on welding/metal projects.

    I changed out the filters on one of my masks today based on the outside appearance. The inside looked pretty good.
    I dated the new ones I put on to see how they look in a few months. I realized after I wrote it that the 1st is tomorrow.

    I really should wear a respirator more often.

    Wearing one now plus eye and ear protection to use a cut off wheel on an old cylinder.

    Of course I am using a cut off wheel on the grinder without a guard so it all balances out.
