3MN95 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)

Excellent dust mask and a good value.

I like these filters as I find them easy to breathe through and are comfortable to use in public or while working in the shop or yard.

I use it when I do my bug spray every 2 months. I use a powder insecticide that makes dust when I mix it with water. Using this M95 mask eliminates all of that. Snug, and does the job. I use this through the whole spray process and feel confident I'm taking care of business safely. I'll order again when I need some, but these are going to last me a long time

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.

Good for purposes intended

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!

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!

I've tried a number of these inexpensive respirators, and have settled on this one as my favorite. The 3M 8511 fits well, is comfortable, has good straps (fabric covered; won't tug hair), and has an exhalation valve (I wear glasses, and this helps keep them from getting fogged up, besides making breathing easier and keeping the mask cooler). They're also pretty inexpensive. Yes, you can find slightly cheaper N95 masks, but not at this quality level. Great for sanding or any sort of construction work with particulates in the air. I have them in all of my emergency preparedness and disaster response kits (I volunteer with CERT and the Red Cross, among other groups).The one thing these masks aren't ideal for is to put on medical patients that may have a contagious illness (for that purpose, you don't want an exhalation valve. The 8210 or a cheaper dust mask would work in that case).If you need more protection, or a mask that you can use longer before you need to toss it (you can use these more than once, but not forever), look at the 3M Particulate Respirator 8233, N100 (blocks 99.7%+ of particulates, rather than 95%+), or the similar 3M 8293 P100 Disposable Particulate Cup Respirator with Cool Flow Exhalation Valve, Standard, which adds an additional level of protection against airborne oils and similar chemical contaminants.A cartridge-style respirator is also a good choice for anyone that finds themselves using these regularly. My favorites are the 3M 6502QL Rugged Comfort Quick Latch Half Facepiece Reusable Respirator, Medium and the 3M Medium Half Facepiece Reusable Respirator 7502/37082(AAD), Respiratory Protection, Medium. Both well-fitting, comfortable, and fantastic.
