3M*- Aura 1870+ Niosh Certified - Pack of 20

I think they're genuine, came in 3m box but was in Chinese and English which I found kind of strange but they have an expiration date.The fit is okay, I was going to use them for masks in public because my wife is immune-compromised but didn't like how the rubber bands felt on my neck, so now I use them when I'm cleaning out the yard. Didn't get super damp inside and allergies didn't bother me at all. Wore them in the sun and wasn't suffocating, didn't smell the mower gas and glasses didn't for up much.Well worth the $8 something I paid for them for 20 masks, would buy again if needed.

Great product excellent price

Masks are legit!

Legit masks. Some of the reviews talk about packaging, fit and legitimacy of the product. I purchased them in April 2025. Mine were packed in legit 3M boxes, and individually wrapped. Boxes read “Made in USA with globally sourced materials.” The boxes have a lot number, date of manufacture (02/22/2023) and expiration date (02/22/2028). So mine are a couple of years old, which explains the sale price. The masks fit my large face and head fine, but do fog up my glasses a bit. I don’t plan to wear them all day or for hours on end, but in an emergency they would work fine. No crazy chemical smell other than the faint smells of the mask components themselves. Hope it helps.

Will buy more! Love them!

This 3M mask gets the job done and seems to provide a decent level of protection. It arrived in time. Each mask is packed separately. There is no box or anything, just the masks. It appears to be a genuine 3M product to me—though to be honest, I’m not entirely sure how to verify authenticity beyond the basics. It looks fairly generic compared to other 3M masks I’ve used in the past.One thing I did notice is that this model runs a bit smaller than the 3M 9205, which I’ve used before and found slightly more comfortable. This one still forms a decent seal, but those with larger faces might find the fit a little tight. It’s not uncomfortable, just noticeably more snug. But the price cannot be beaten.The expiration date printed on the packaging is sometime in 2027, which gives me confidence that it’s still within a safe usage window. Overall, it’s a decent mask that meets expectations, though I might stick to the 9205 when I need something roomier.

I got these on sale, and they’re not only a STEAL, but also super great quality. It fits my face perfectly and I have a smaller face. The seal is good, the interior bridge that sits on my nose is super super comfortable and the rubber straps don’t make me feel like my head is going to pop. Although very comfortable, it does have a strong chemical smell. But it’s better than smelling stinky people and breathing in their illnesses. You’ll become nose blind eventually, if it’s really bothers you, they’re all individually wrapped so perhaps you should open them and let them air out a little so the smell goes away. I have a sensitive nose and it doesn’t bother me as much as the smell of other people.

I purchased these from Amazon and not another seller thinking I was guaranteed a fresh, authorized product. What I received was a clear plastic bag with the 20 individual masks inside. No manufacturing code for me to check with 3M to guarantee their authenticity and no date when these masks expire! What?No where in the listing did it state that these were bulk packaged. I would never have purchased them if it did state this information. One star to Amazon for this negligence. Otherwise these are my favorite 3M masks to wear. My husband has COPD so we wear masks in public to avoid him catching a respiratory disease and suffering while breathing. These masks are easy to wear and breathable.
