Top reviews from the United States
- GuyFANTASTIC PRODUCT!!!!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.
- Ellen FComfortable, well made, and part of a smart home supplyI keep a box of these as part of my household’s emergency and seasonal preparedness kit. They’re NIOSH-approved and reliably made, with a consistent fit and a noticeable difference in breathability compared to lower-grade masks.
The Cool Flow valve makes them more comfortable during extended wear, especially in warm weather or while moving around. The metal nose piece molds easily and helps keep the seal secure without discomfort. I’ve used these during wildfire season, dusty DIY projects, and for general respiratory protection when needed.
Each mask feels durable and consistent. The straps hold up well and don’t overstretch or snap easily. I’ve tried a range of N95 options over the years, and this continues to be one of the best I’ve used.
A product like this isn’t for everyday use in most homes, but when you need it, you want it to work well. This one does. - CatieGreat Mask!My husband has horrible allergies and gets a sinus infection anytime he does yard work. He has used many different masks but this one seems to be the best one for him. The N95 components blocks a lot of the allergens and the cool flow valve allows him to breath a little easier than a traditional mask. He is a tall man and the masks stretch well and provide great coverage for his mouth and nose! He only uses them for one time then disposes but they are pretty durable and could be reused if only used for a limited time.
- I Review, Therefore You BuyOutstanding Defense During the Recent LA FiresReview 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. - The EngineerWorks well at filtering incoming airGreat filter for allergens, dust, general work around the house. When you vacuum. When you work on your car. When you mow the lawn. I like the built-in vent. It's stuffier to breathe for sure, but for a mask it works as well as you're going to get I think, and filters well. Definitely minimizes allergies and the lungs feel nice not sucking in contaminants. I usually use these for several jobs before changing when they get dirty.
- DesireeFeels good to feel safeTheir flow to this mask is really breathable. It feels as if I don’t have the mask on the seal. It really feels secure, knowing that I can walk around where I am and knowing that I’m safe and I’m able to breathe the ear straps that it goes over your head so it’s not an ear strap and it’s very stretchy. It’s not something that’s gonna irritate you while you’re walking around. There’s a lot of comfort to it and if you’re really interested, I would totally recommend. I’m totally buying it again. It does feel like a really good mask to use, especially in areas where it’s not so Good for you. This is something that you’ll be able to tolerate walk around with and feel like it’s not even on your face.
- Kevin MangualLife saverWorking inside an Amazon facility under construction and the farmland prior to this was polluted with pesticides and harmful chemicals and the poor air quality inside the facility. I was taken to the aeR twice from over excessive wheezing and hardly able to breathe. This saved my lungs and while I wish the masks can be be bigger to accommodate me, it protected me from the chemicals and dust and was to do my job with little to no wheezing
