3M 8511 Particulate Disposable Respirator, N95, Pack of 80, NIOSH Approved, Cool Comfort and Fewer Pressure Points with Dual Attachment for Grinding, Sanding, Sawing, Sweeping, Dust, Smoke

Good product and good delivery time.

Following the terrible fires in Southern California in January, I ordered these because I was running out of other N95s that I had had through COVID. I like the fact that you're not re-breathing carbon dioxide. You inhale pure air and exhale and it comes in and goes out the way it's supposed to. While I've worn them for long periods of time and they're not terribly uncomfortable, a whole day in them is a bit much. Doable but what can I say? Who wants to wear a mask all day? Nobody. I have no problem with the its functionality, no issue with my glasses fogging up, it fits well, and I'm wearing them for the smoke and particulates which might be in the air 50 miles from the fires. Probably not much but enough according to the AQI that we should be wearing these masks and according to my own doctor due to my lung problems. So there you go. I put one on to motor around in in the morning, take it off at lunch time and put a new one on to go outside after lunch to motor around some more. I do have to say that it does me no good to put on makeup on a day I'm going to be wearing a mask however! 🤣

I bought a large number of these because my geographical area was overwhelmed with smoke for several months due to the heavy forest fires burning in nearby states. I have asthma and the smoke was making me feel like I'd been kicked in the chest and dunked underwater. I was researching online videos about how to keep the air clean inside your house when there's smoke outside, and one video happened to mention these respirators for when you do have to go outside. I had seen them on home improvement shows but I honestly had never used one myself and I had no idea how much better they were than those cheap medical masks at the drug store. I must say that I'm glad I went ahead and bought this brand because they are much more durable than the medical masks. These masks also have a particulate chamber in front that makes you feel like you're breathing fresh air, which makes the overall feel of the mask less constricting. I used these through all the smoke issues, and since the smoke has cleared, I've continued using them for any projects that may agitate my lungs, such as using paint or cleaning pet cages. They are very well constructed and I do feel an improvement in being able to breathe when I wear them. I also like that there is a metal piece on top to mold to the nose so my glasses don't fog up so much while I'm working. I'm very pleased with this product and I would recommend it.

We buy these constantly for dust protection for our work. The N95 rating means it captures 95% of the dust that passes through it. Since the Coronavirus has hit the media's attention, these masks have tripled in price and this particular one is no longer available from this source at this price. Ebay ads list these as Coronavirus masks. PLEASE NOTE that a virus is 0.1 microns or smaller. A true HEPA filter captures 99.97% of anything 0.2 microns in size or larger. This is NOT HEPA-rated, so a virus would certainly pass right through it. For reference size: your hair is about 0.75 microns. These are excellent for what they were designed for - dust. They are comfortable and last all day unless you sweat a lot. Once they get wet, it becomes exceedingly difficult to breathe, but that is true of all of these paper masks.

We've been ordering this item for the past year and have been totally pleased. Shipping time is perfect, the product is perfect, and the price is AWESOME. Don't know how we were able to afford these before finding them.

3M is the best company for getting PPE products . They make quality goods. These N-95’s work well for dust and odor infiltration

These work as expected.
