Protects you from dust. Great quality. Kind of breathable. Kind of comfortable. Decent price.

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

Sometimes, when I'm mowing the grass in the spring, I seen pollen in the air like a white cloud. A mask like this helps me not have such a bad allergic reaction to the heavy pollen. The exhaust valve on the front makes the mask work much better, because it doesn't get as steamy inside. The masks are very well made too, so the rubber bands don't break off. The edges are pressed in a way that makes them fit better against my face, and the little metal thing across the bridge of my nose has a special shape that makes it fit better then the cheap, blue covid masks. The masks are much thicker than I expected. They work very well.

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.
