These masks are excellent. We're renovating a very old barn with dirt floors and decades of dust and grime. The other week, we spent a maskless hour cleaning out one section of this barn and had to stop because my husband and I both had asthma attacks and were struggling to breathe until the next day. I immediately ordered these masks. Yesterday, we went back out to work and wow do these masks make a HUGE difference. No asthma attacks or dust/manure in our noses or lungs. We worked for a few hours without any issues. They're also much cooler than most masks I've worn. I didn't feel like my face was sweating off. Due to the elastic bands, they also fit well - neither too tight nor too loose on my husband's larger head or my smaller one. Overall, I'm incredibly glad I bought these and won't be doing any renovation work without them ever again.

My wife is a dog groomer and has AGS. She had a reaction recently so we tried one I use in my shop. It works great. The vent makes a huge difference. It keeps her goggles from fogging up.

These are my go to masks for the woodshop. I need the valved mask to exhale without the effort that the regular masks require. The price is great for a quality mask. I have discarded my other masks that purport to filter as well, but with difficulty in exhaling, and with flimsy nose pieces. These just work.

I use a lot of respirators when mowing and doing other chores that involve dust, pollen, and other particulate matter. These do a good job of filtering, fit well, and are comfortable.

Seems well made . Good price

Great 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.

This is a really useful product which helps you breathing fresh and clean air in comfortable way. I bought this product last December when I went back to my home town for winter break. I come from Beijing, capital city of China. I love my home city, although I heard the air pollution is terrible in the few years. My friend told me I have to prepare to prevent myself form this bad pollution. As a result, I bought these 3M masks. I tried to use the mask immediately after I landed off. In fact, the effect is amazing! I can definitely feel the air is fresh, because the air is smelled different. While, I stayed in Beijing for about a month, based on the weather issue I wear the mask even every day. After a few days used for one mask, I surprised the internal of the mask is turning to black. We said the bad air pollution in Beijing is because the level of PM 2.5 is increasing. PM 2.5 is fine particulate which comes from human activities such as automobiles’ uncomplete fuel burning and all kinds of chemical industries’ trash discharging. I read an article which talks about 3M N 95 respirators. It said N95 respirator can filter seven types of particulates which means even 95% of airborne transmission’s particulates can be filtered. Personally, I think this respirator is really helpful. It not only can prevent air pollution but also can protect you when you need to do some works in high level of PM 2.5 areas. Moreover, this is one of the most comfortable masks I have every used. 3M use their technology to eliminate heat and wet inside the respirator. Especially for the people who wear glasses, this mask will never make a fog in front of the glasses when breathing. Although I didn’t find any information to support my view, I think this mask is using cottons which make it soft and comfortable. On the other perspective, I think this mask is too tight to move. Personally, I don’t like to tie my hair up in winter, so every time I try to remove the mask it will mess my hair up. Although it is hard to remove, tight coupling with face is helping to prevent pollution come into the mask. Over all, I like this powerful air cleansing functional mask with comfortable material. So I will give 5 starts for the product! As a conclusion, I really encourage you who have same situation with me to buy this product. Because it is really useful to me and I believe it will be useful to you as well! Hope this review can help you when you make purchase decision.

Working 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

Lo compre para mis trabajos de hobby de carpintería, altamente recomendable, protege y es cómodo, con el prácticamente no respiras nada del polvo o particular de los cortes en las maderas

3M is a very known respirator manufacturer. As usual it's quality is non comparable in local market

bon masque

perfecto!

Good masks, I tried many but these are my favorite, as a drywaller/carpenter it sure helps a lot especially considering my nose is a bit sensitive to dust. Would recommend
