(More customer reviews)Filter material: Thick, soft, seemingly multi-layered. I feel much better with this material between my lungs and the particulates than with those cheap bulk dust mask. The big problem here is that, despite the exhaust vent, moisture still builds up on the inside which causes the inner-lining to disintegrate and get wooly. Though the material doesn't break off into bits, it's still unpleasant to have warm, moist, wooly material touching your mouth. In fact, it makes the mask too uncomfortable to wear in my opinion, thus severely curtailing the life-expectancy of this product. I'd say I got about 20 hours from it.
Fit: The two adjustable elastic straps do their job well and won't easily break - much better than the rubber band and staple type that break so easily. To help seal the mask, there's a built-in aluminum nose-pinch. The seal material looks like a flexible styrofoam, about 1/16" of an inch, which I don't think is the best sealing material as it's too slick. Also, despite the exhaust valve opening on exhalation and close on inhalation, the lower part of my goggles would still get fogged from the exhalation coming from the top of the mask. This would indicate an imperfect seal/fit which of course means you're likely also inhaling some unfiltered air. I'd have to squeeze the nose-pinch and move the mask further up my face for this to temporarily stop.
Overall, I'd say this is much better than those cheap bulk jobs which are virtually useless. If you need to supply a bunch of people with a good quality disposable, the 8293 P100 may be a good choice. If you're just getting one for yourself and want high-quality dust mask, I'd recommend spending a little more money for a higher-end rubber one with removable filters. Though I haven't tried one yet, that's what I'm getting next. Meanwhile, I'm going overkill with my dual-filter fume/dust respirator. My lungs are the only ones I've got.
