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)

These masks are excellent. We're renovating a very old barn with dirt floors and decades of dust and grime. The other week, we spent a maskless hour cleaning out one section of this barn and had to stop because my husband and I both had asthma attacks and were struggling to breathe until the next day. I immediately ordered these masks. Yesterday, we went back out to work and wow do these masks make a HUGE difference. No asthma attacks or dust/manure in our noses or lungs. We worked for a few hours without any issues. They're also much cooler than most masks I've worn. I didn't feel like my face was sweating off. Due to the elastic bands, they also fit well - neither too tight nor too loose on my husband's larger head or my smaller one. Overall, I'm incredibly glad I bought these and won't be doing any renovation work without them ever again.

Routinely purchase these masks for work in my shop. They are high quality and perform well consistently. The price as decent at the time of purchase, but it doesn't hurt to shop around.

My wife is a dog groomer and has AGS. She had a reaction recently so we tried one I use in my shop. It works great. The vent makes a huge difference. It keeps her goggles from fogging up.

These N95 fit more comfortably than some other models. I appreciate the little filter valve that makes breathing easier.

Review of 3M N95 Respirator 8511 with Cool Flow Valve – A Lifesaver During the LA Fires The 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.

OK, I got these to use when I weed eat and mow the yard. I got really tired of the paper mask getting soggy from sweat and making breathing difficult. This mask is stiff and stands away from my face. Sweat doesn't interfere with it, and my safety glasses don't get fogged up.

Great comfortable mask for protection.

Good filtering. Snug fit. Easy breathing even with exertion.

Lo compre para mis trabajos de hobby de carpintería, altamente recomendable, protege y es cómodo, con el prácticamente no respiras nada del polvo o particular de los cortes en las maderas

3M is a very known respirator manufacturer. As usual it's quality is non comparable in local market

Très bonne qualité.

using this for few months now and there elastic durability is good and superb protection and the temperature inside the mask is not much as compare to valve less mask of 3M and easier to take the breathe in this mask and if you are from hot humid climate this is good buy for you still 200 per piece is little much still you are going for quality and comfortability this is the best buy packaging was good and reached on time for me
