3M Particulate Respirator 8511, Pack of 10, N95, NIOSH APPROVED, Cool Flow Exhalation Valve, Disposable, Braided Comfort Strap, M Noseclip, Personal Protective Equipment

Better with exhaust valve they work great.

It stops the smell of smoke from wildfires. The price was good for it. I am asthmatic, and could breathe with this on.

like highway driving... while the masses; masked and unmasked, stayed home and built their toilet paper bunkers...cut 20m off of my commute.these 3m n95 masks, so ubiquitous on my construction sites, disappeared from Feb2020-dec2021. the replacement masks were a mix of shoddy to questionable.3M, you might have poisoned water supplies for decades on global scale, but your N95 masks truly are the gold standard of one and done disposable tech, unlike your earplugs, which caused many an American servicemember irreparable hearing loss.when your board members are finally lined up against an alley wall, i hope some of you take comfort in the value for money your 3M N95 facemasks have provided.

I like this N95 mask because it's rigid enough to keep the mask off your face so that it doesn't constrict your breathing when breathing in/out. Lasts fairly long, ultimately attracting dirt and so you must discard it for a new one. You have to adjust the top metal strip to seal your nose better. Fits well at the chin. Straps go behind your head; I like these instead of the ones with ear loops as those always slip off my ears.Prices have gone up for this item quite a bit: 10 for $30 vs 10 for $22, and that's within a year.

This is a well-made respirator; it does what it is supposed to do. However, I can't imagine a man could comfortably wear these, as I am a female with a somewhat narrow face and the mask dug into my cheeks and left indentations in my skin for quite a while after I took it off. I don't know if a longer elastic strap would help or just that the respirator needs to be made larger in circumference. At least you don't have to worry about any particulates getting through that seal! Ugh. I wish I wouldn't have bought a pack of 10. They are not comfortable from the get-go.

These are not a replacement or a substitute for a fully featured respirator. But if this is all you can get, it's the next best thing for keeping particulates (in plain English: dirt) out of your lungs. They seal well so that contaminated air does not get past the filter. Air draws easily through the filter material; I don't have to gasp for air. I can breathe normally all the way until the mask becomes unusable. The exhalation port is the best (and my favorite) feature. It eliminates the heat and moisture build-up inside the mask, making it much more comfortable to wear for extended periods than the solid cloth or filter paper masks. I'm not in love with the two strap over the head elastic band system that holds the mask in place, but it does keep the mask firmly in position. it does filter very well. After a few uses, or use in very dusty/dirty conditions, I can see the particles all over the outside of the mask. It even filters pollen. I have allergies and there have been times when mowing the lawn induced an attack. I run inside the garage, put on the mask, and within fifteen minutes of resting, the attack disappears and I can work outside using the mask for the rest of the day in complete comfort. These masks are also durable and, depending on condition, be used multiple times. These are an inexpensive way to protect yourself.

I have brought many,many different kinds for yard work.These are light, comfortable ,very little smell, aired for a few days and they were good. Kept grass cutting smell out, dust too.They do have a medal to fit nose with some adjustments you can stop fogging. For the money these have been the best, will buy again.

Fit nicely and work as described. A current necessity during these fire times! Much better than other brands I’ve tried. Will buy again!
