3M N95 Respirator 8511, Cool Flow Valve, 10 Pack, NIOSH-APPROVED, Advanced Filter Media For Easy Breathing, Comfortable For Long Periods Of Wear, Helps Filter Pollen, Mold Spores & Dust (8511PB1-A-PS)

I have allergies and I sweat like a, well I sweat a lot when I’m working. I have to wear a mask and all of them fog up my glasses and then they get soaked with sweat and I can hardly breathe through them. This mask fixes all my problems with the vent valve and the re-engineered metal strip above your nose, it no longer fogs my glasses. And somehow the way it’s made, it gets soaking wet, but I can still breathe fine through it. GREAT PRODUCT!!! I have worn the first one through three separate lawnmowing’s, and will continue to use it as long as it works and looks clean. So that makes them pretty economical.

Item is exactly as described. Performed well against cement dust and other particulates. Great to be able to not fog up your glasses. A bit of a tight fit, but not a struggle to get on and I have a somewhat larger head.I won't take a star off because this isn't a product problem, but of the 4 boxes I've ordered, each has been poorly packaged and has arrived with some damage from minor dents to ripped. Product has always been unaffected though.

I wanted a mask to where while mowing due to the dry grass and pollen. These masks work great. I can breathe easily, and my safety goggles do not fog up. They are light weight and I can get a good seal to keep out the dirt and pollen.

Bought because of the brand name and am happy to say the quality is as expected. This product is a bit more expensive but worth every penny.

Review of 3M N95 Respirator 8511 with Cool Flow Valve – A Lifesaver During the LA FiresThe 3M N95 Respirator 8511 with the Cool Flow Valve was an absolute game-changer during the recent LA fires. With the air thick with smoke and ash, this mask provided reliable protection, filtering out harmful particles and making it much easier to breathe safely.One of the standout features is the Cool Flow Valve, which significantly reduces heat and moisture buildup inside the mask. Unlike other respirators that can become stifling after extended wear, this one remained comfortable even during long hours outdoors or while navigating smoky conditions. The adjustable nose clip and soft inner lining also ensured a secure and snug fit, minimizing gaps and preventing smoke infiltration.Another major plus was the durability—even with frequent use, the mask held up well without losing its shape or filtration efficiency. Whether driving through the worst of the smoke or simply trying to go about daily tasks in the hazardous air, this respirator provided peace of mind and essential protection.If you live in a wildfire-prone area, work in construction, or need solid protection against airborne particles, the 3M 8511 N95 is an excellent investment. It’s comfortable, effective, and truly a lifesaver when air quality takes a turn for the worse.

Must have for those who have poultry or cats! I used to clean my coops and cat litter boxes without a mask and I’d always have the worst sore throat the next few days due to all the dust these masks provide a perfect seal to keep you from breathing in any dust and you can barely smell through them which is great if you’re sensitive to the smell of cat litter boxes!

Spend a little more and get a lot more! These N-95 masks are quality, from the legoitimate strap arrangements to the exhaust valve that eliminates fogging of your safety glasses. The exhale is effortless and the valve doesn't require the slightest effort; it also directs the exhale downward, away from your face. Minnesota Mining and Minerals (3M), always produces quality and well engineered products. Made in the USA! Pay a little more for your safety and comfort!

purchased for guys on the shop floor they love the fit and are able to wear all day
