    Respirator filter alternatives

    Hey guys. I am a novice at home welder that only does a few projects a year. And generally just a quick build or repair on something small.

    I am taking on a huge for me project this coming week and will we welding a lot. All MIG and regular steel. With the exception of some zinc coated parts. And I am aware of the awful crap that comes from welding coated parts. Those parts will all be quick tacks but those few welds are what has me the most worried. I will be grinding off the zinc where it will be welded.

    I have a left over pair of P100 filters for my respirator I bought WAY back in 2016. And although the one pair left is still sealed up, the expatriation was 2018.

    Seeing as these are now impossible to find, 2 questions.

    One, is the expired filter still offering protection? and 2 what are some alternatives?

    I have thought about building a small fume extractor of some sort to at least pull some of the smoke and fumes away. However I worry that i wont be able to make one that does a good enough job or pulls too much and pulls my welding gas away. I am sure my box fan will be way to much air movement.

    thanks as always

    I suspect the particulate filters like a p100 will work well past their expiration date. I also think youíd be able to smell the smoke if they arenít working well. That said, it seems like various 3M filters are available, just more expensive than normal.

    You're right, the box fan will not work well. But if you can find a squirrel cage blower you can set it up to blow to the side of your welding and it can work very well. A little trial and error will tell you how close to your welding your air stream has to be to remove the smoke with out messing with your welding gas. Some times it will work best blowing over the top of your welding area. If you want an easy way to check air flow around your welding, just light a candle and watch the flame.

    I would say your primary hazard is from any grinding you do. That dust or particulate is more hazardous in my opinion than the fumes from welding mild steel. Think of grinding dust as being as hazardous in the long term as welding galvanized metal.
    The filters that are still sealed are fine.

    Re: Respirator filter alternatives

    Thanks everyone for the replies. I appreciate the added insight. I saw a home built fume extractor on the Miller forum made out of bathroom exhaust vents. I think I’ll try and make that along with my respirator.

    Thank you all again. I do love this forum. It’s nice to post questions and get flamed all to hell.

    The filters will be fine. An expiration date is required by the regulatory body and 5 yrs is pretty typical, but they don't turn into pumpkins at 5 yrs. Unless you stored them on the dash of a black car stored outside in Arizona year round, they should be fine. Take a look for any damage first, if you are concerned, and if none, then use them in confidence.

    It seems some kinds of filters and respirators have gone up in price considerably. I'm glad I already have two LPR-100's because the current price on them is easily twice what I paid a couple years ago.

    Is a p100 filter good for filtering out galvanized fumes? We use a cutting torch on galvanized every once and a while.

    Yep. Just make sure the face seal fits you well and you are good to go. P100 is the highest filter efficiency available in the US.

    3Mô Particulate Filter 2091/07000(AAD), P100

    Details
    Exceptional 99.97% filter efficiency meets NIOSH P100-series test criteria
    Advanced Electret Media (AEM) provides lightweight, easy breathing comfort
    Versatile protection against many oil and non-oil based particulate contaminants
    Bayonet compatibility allows use with many 3Mô half and full facepiece designs
    Wide range of applications reduces inventory needs and training requirements
    NIOSH approved for environments containing certain oil and non-oil based particles.

    The 3Mô Particulate Filter 2091, P100 helps provide respiratory protection against exposure to lead, asbestos, cadmium, arsenic, and MDA. The filter is effective for concentrations up to 10 times the Permissible Exposure Limit (PEL) with half facepieces, or 50 times PEL with quantitatively fit tested full facepieces. This filter helps protect against a wide range of oil and non-oil based particulate contaminants. 3Mís Advanced Electret Media (AEM) provides a comfortable lightweight, easy-breathing combination. The 2091 is commonly used for welding, brazing, torch cutting, metal pouring and soldering. Inventory needs and training requirements of safety equipment are reduced because this filter works for many different applications. The filter is both flame and water resistant. Industries where this filter is commonly used include agriculture, construction, general manufacturing, pharmaceuticals and primary metals.

    The filter works with a wide range of facepieces, including 3Mô Half and Full Facepieces 6000, 7000 and FF-400 Series. If used with 3Mô Adapter 502, the filter may also be used with 3Mô Respirator 5000 Series or 3Mô Cartridge 6000 Series. The filter is NIOSH (National Institute for Occupational Safety and Health) approved for environments containing certain oil and non-oil based particles. The filter has been assigned the color code ďmagentaĒ in the NIOSH system. Passing NIOSHís P-series test criteria, the 2091 P100 filter provides at least 99.97 percent filter efficiency against particles.

    Breathing hazardous particles can pose a risk to your health. NIOSH, a Federal government regulatory agency, has tested and approved the 3Mô Particulate Filter 2091 to help reduce exposure to certain particles.




    Used with a 7500 series half face respirator which is reasonably priced, and fairly comfortable. These cartridges a made specifically for welding cutting brazing, and soldering. I believe they have a small amount of activated carbon to help with fumes from the cutting and flux vapors.. I also use 3M- 8212 (N95) face mask with similar properties (cutting welding soldering).
    Its always a good idea to check the manufactures recomendations when deciding which one to use. When in doubt though, any mask is generally better than none in a nuisance situation. Nuisance meaning exposure to something that won't cause severe immediate harm from exposure. Like grinding dust or welding fumes.

    good luck https://www.weldingweb.com/images/smilies/smile.gif
