3M Half Facepiece Reusable Respirator Assembly Kit 6391, Size Large, P100, Lightweight, Comfortable, Easy to Adjust, Includes 2091 Particulate Filter, Welding, Soldering, Asbestos

It works, it fits, and it's comfortable. I previously had the medium size which kinda-sorta fit but I found I was constantly fiddling with it to make sure I maintained a good seal. With this one I put it on and forget about it. There is another type of mask that has a "drop down" feature, which means when you undo the clasps at the back the mask drops down off your face. That's handy if you want to pop it off for a minute to talk/eat/drink etc but it's not a big deal to lift this one out of the way if you need to. Some reviews commented on it coming without the filters. Mine came with the filters, as expected. Not sure if some people are ordering from third party sellers or what. I'm still using the filters that came with my previous respirator and they fit just fine. I wore my respirator for several hours while pulling down an elderly lath-and-plaster wall and some 1930s drywall. Previously I'd used a paper dust mask for that kind of work and found I got enough dust in my nose to be annoying. After some hours of pulling stuff down and cleaning up dust (including getting quite close to piles of dust as I swept them into a dustpan, prior to sucking up the remainder in a shop vac), virtually nothing got through. The very small amount that got through suggested I didn't have the mask fitted quite perfectly, but obviously it was pretty close. For my purposes I'm not hugely bothered if I don't have a perfect seal - my usage is more for building dust rather than specifically hazardous material. That said, this thing feels like it would stand up just fine if I was removing nastier material than plaster dust.

Wonderful face mask. Filters very well & doesn’t leak & fog up glasses. Comfortable to wear for hours. Seems to last forever. I have one that’s over 25 years old & is good as new. Got another to get more filters & have a backup when I clean the inside of the other from runny nose or sneezing.

Works great easy to use

Cheap health insurance

Comfortable and reliable. It’s not as comfortable as it could be, but for 20$ it’s very solid. Fits my welding hood perfectly and no weird silicone smells. The design is pretty versatile for different sized heads.

Great for welding your gonna want some baby powder cause it gets a little sticky but keeps the fumes out of your lungs very well buy one and wear it!

Listing plainly stated that the filters came with the mask. There were no filters in the package. If i have to buy the filters separate it will almost double what this mask should cost! NOT HAPPY!

I use this when cutting open converters, and it does a great job keeping dust and debris out. Comfortable fit, solid seal, and easy to swap filters. I’ve ordered this setup multiple times — dependable and worth every penny for the protection it provides.
