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)

good fit for my face comfortable and good quality. needed for sanding drywall repairs and the mask worked well and i was able to breath pretty easily with a good fit.

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.

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.

These work fantastic for sanding primer and working under vehicles to keep gunk from falling in your mouth. Definitely will be repurchasing.

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.

I’ve bought these several times. They’re comfy, fit well, and the quality is great for the price.

Masks are good quality, straps are sturdy and breathing is easy. prompt shipping. Would buy again.

They seem really great and high quality. I have already used one. How does one really know they work though? I can only hope they do. Surely with them being high quality, they do. :)
