3M Half Facepiece Reusable Respirator Assembly Kit 6191, Size Small, P100, Lightweight, Comfortable, Easy to Adjust, Includes 2091 Particulate Filter, Welding, Soldering, Asbestos

The rubber is high quality and it is gentle on your face. It's easy to breathe in it. 3M is a great company, and they make excellent products. This is one of them.

Works as intended and fits very good to the wearer's face, not letting any dust in. Overall very satisfied!

Fits well and doesn't feel suffocating like most masks of this type. Filters are easy to remove for replacement.

I'm grateful to have this mask as breathing is far easier than my N95 masks BUT after about 1 hour my nose area really aches from the pressure of the mask. I find I am adjusting it a lot to relieve the pressure or swapping between my N95 and this P100 during a long stint like a 6 hour cross-country flight. Obviously this is not fashionable either so you have to know you're going to get stared at! Better than being sick. Just wish it didn't hurt my face so much.

The media could not be loaded. The fit:I have a small face, so I am reluctant to purchase products in adult size small, but this was surprisingly perfect.The quality:It’s very light weight, which I appreciate. The flexibility offers a ton of movement, so I don’t feel tied down or restricted. Due to the curvature of the design and the soft materials, I don’t feel like it cuts off any circulation. It also allow you to adjust straps to your preferred fit.Price:I think this is a pretty great price considering there are many others that are on the market at a higher price that offer the same protection.I also really like the design. Bonus.Use:I’ll a Carpenter at heart, so moles in my garage working on a project. Between my mask and my vacuum, I’m set.

I already have a small that I use with the bad-ass chemical filters so I can access public restrooms (my body cannot tolerate the chemicals in artificial fragrance, and most restrooms these days have "air fresheners"). Fits well, although I have to be sure to check the seal performance before each use — standard operating procedure for any respirator.I ordered a second mask for use with the dust filters (that were indeed included) for a dusty project around the house. I have no idea if the new mask will work the same as my previous mask or not because I can't get it near my face without burning my throat and lungs! The bag the mask came in REEKS of Febreze or a generic equivalent. The mask does as well, and I can't tell if it absorbed the fragrance from the packaging or if it is the source of the stench. Either way, I can't use it.For those who do not know, this fragrance is made with linalool, and it's neurotoxic to EVERYONE. Some of us feel the effects faster than others, but nobody who is using a respirator (which already restricts oxygen by default) needs to be inhaling a chemical that will, over time, make them tired and loopy (compounding the effects of lower oxygen).Dumb, dumb, DUMB move, 3M. Poison people who are trying to protect themselves? Y'know, it's totally OK if plastic smells like plastic. That's how we consumers can tell if it's actually clean or needs replacing.Won't buy this ever again unless I have solid proof that this problem has been rectified. Totally disgusted that anyone would be stupid enough to add poison to an article of PPE.

I work for a small woodworking business and I ordered these to protect against sawdust and other contaminants that come from sanding/planing/joining reclaimed lumber. So far I'm extremely pleased! They're quite lightweight and the rubber is very soft and comfortable; which is exactly what I was hoping for since I'll be wearing these a lot. The filters go on nice and easy, the straps are easy to adjust - what more could I ask for? I ordered a small for me and large for my co-worker (I'm a girl and he's a bearded guy), there's not a huge difference in size but they both fit just fine. He felt like it was going to work with his beard just fine for what we're using it for. If you want a better seal you can use a bit of Vaseline around the edges if you're trying to work around a beard. So far I'm super pleased with these!

Not sure how to rate "thickness" .. but overall this is a comfortable mask, seals well and fairly comfortable with one exception. It is a little too short from top to bottom. So it's either pushing on the bridge of my nose, or if I move it up, it presses on my chin and pushes my lower jaw back. In an 8-10 hr day, I get either a headache from the jaw pressure, or my nose hurts because of the constant pressure. I'm a fairly large guy, so someone with a smaller head will probably have a nice comfortable fit. If you are a bigger person, you won't want to wear it for long periods.
