3M 8210V Particulate Respirator with Cool Flow Valve, Grinding, Sanding, Sawing, Sweeping, Woodworking, Dust, 10/Box

I bought a box of these to have on hand for emergency and also to use in my wood working shop. I have tried 3 other brands and decided that it was easier to breath the dust than to fight with the mask. These are shaped to fit an adult face much better than the El Cheapo 10 for a dollar masks and the valve on front is a very nice feature that prevents your glasses from fogging up and allows you to breath a lot easier, especially when they start getting plugged up.The straps are the same ones that come on the cheaper masks but the mask material is about 4 times thicker and softer material. Very comfortable if wearing for long periods of time. I think the straps will last much longer on these because you aren't taking them off every few minutes so you can breath and clean your glasses.I don't know how durable they are, but one has lasted for several weeks of sawing, sanding and painting in the shop and although it is getting pretty dirty it is still doing the job. Usually the cheaper ones only last a couple of sessions.I think these are worth the little extra you pay for them.

For a good, comfortable mask which can be worn with eyeglasses and not fog them up, this is really a good buy, and nice quantity to keep on hand. They are very comfortable, and the dual bands keep the mask fit and secure on your face while you work. The adjustable band on the nose piece helps it to seal very, very well, and the outlet valve is the clue to not fogging your glasses.This is NOT a fume mask for protection against solvents or pesticides, note the product description: "This respirator is designed for use for particles such as those from grinding, sanding, sweeping, sawing, bagging, or other dusty operations. The respirator incorporates 3M’s proprietary technology with advanced electrostatically charged microfiber filter media designed for ease of breathing. This respirator is compatible with a variety of protective eyewear and hearing protection.

Excellent product. Filters very well. Can go outside without breathing problems.

I have developed reactive airway disease, which is not a good thing when a person farms for a living. I use these masks to reduce the sheer quantity of particulates (especially dust) that I'm exposed to when working outdoors. Especially during times when the hot summers and north winds create mounds of dust on every surface. As masks go, it's bearable. No one likes to have their face trapped in steamy exhalation all day but....the venting helps a lot. I do end up with heavy perspiration on my face that is inside the mask on the hotter days. But all in all, this keeps me working and helps reduce my coughing from particulate exposure. For the price, it's a great value, and if the masks are cared for by keeping them clean and being gentle with the elastic straps, they are reusable for days. My only wish is that instead of the elastic being "one size fits all" that they could have an adjustable elastic strap. When first put on they can feel very tight.

Perfect for use in our workshop.

I was looking for N95 and NIOSH approved rating when looking for these masks at my local home improvement stores However, all of them ran out of it because of the bad smoke within the area. That is when I turned to Amazon. I settled on these because they not only did the job but had the Valve to make breathing a little easier.To get a sense of how bad smoke was in my area, it was above 300 Air Quality Index (AQI). Anything above 300 is considered hazardous.Use:The mask is pretty simple to put on. There are two straps to ensure a tight fit. In order to put it on, make sure the metal part is on top and make sure you have a secure fit. It takes only a few second to put on. You then put the straps one above the year and then one around the neck area. The seal is tight but not uncomfortable. I had used N95 masks before NIOSH approved but those didn't have the cool valve. The valve helped breathing much easier. Previously, on other N95 masks, I didn't want to wear it for too long and found myself taking it off because it got too hot and made breathing kind of hard. However, with this product, it wasn't too bad and I let it stay on my face for the whole duration I was outside (couple of hours) with no problem.Overall, I recommend this product if you have to be or live around wild fire smoke. It is much better for your health then having to breath in all those particles, especially if the AQI is above 300. Overall, 5 stars and this product is much better than those without the cool valve because this helps with better breathing.

These mask are too small. The rubber band that goes around the back of my neck is so tight that I almost passed out from wearing one. It's stapled, so there's no way to make it longer. I could cut string holes in the mask and put a string on it, but then the mask would have holes in it.

My standard for years for greatly reducing inhaled dust. Simple, fairly comfortable. Elastic bands usually don't break before you're ready to discard the mask.Note: if you want to stop an airborne virus you need a space suit or a level 5 clean room!
