CooperKN95 Face Masks, 40PCS Breathable Comfortable KN95 Mask, 5-Ply Disposable Face Mask Filter Efficiency≥95%, White

Fits perfectly and the quality is better than most at this price range. I would buy again without hesitation.

Although the size is large, the straps are way too short and do not fit around the ears. As a result these are worthless! The face mask fits snug but alas! There is no way to keep it held snug against the face. Waisted our money and Amazon wont return them!

The masks are comfortable to wear and seem to hold up pretty well. I like them nose piece. It is easy to make it. Comfortable on your nose and keep the air out.

Great quality masks, but they are a bit small for adults. Really tight on my face and awkward to get to fully cover my mouth and nose.

For most situations, we've moved past masking, but it's still a good idea to keep a supply of these for special high-risk situations ... or just in case. Positives about these particular Cooper KN95 masks:+ Made in the U.S. (!), and Cooper is owned by a company with a long, proud history of U.S. manufacturing, so I trust what I'm getting.+ Packaged in sealed, resealable pouches, each holding 5 masks. Good for travel. Better than open packages, or packages where once you open them all the masks are exposed to humid air.+ Sonic welds for straps are more comfortable than staples like BYD uses. And elastic bands are more durable than bare rubber bands.+ Behind the ear design doesn't give quite as tight a fit as behind the head N95, but is pretty good and lot more convenient.+ Multi-layer design seems good. Packages claim 97+% filtration.+ Good price at about 50 cents per mask for pack of 40.The only downside: The pouches have printed spaces for Manufacturing Date and Lot #, but those spaces are blank. Without those stamps, I can't check certification (less of a big deal than it used to be) or know when the masks are likely to be less effective (less of an issue with sealed pouches, but electrets don't last forever, so I still wish I knew the mfg date).Bottom line: For 20 bucks (less than 15 with current coupon), you get 40 high-quality, U.S.-made KN95 masks, conveniently sealed in airtight, resealable pouches. Good to have, just in case the world gets weird again. And if not, good for woodworking, insulation repair, cleaning out the dusty garage, and all the other times when a mask has always been helpful.

I ordered the 40-Pack of 5-Ply Disposable Cooper KN95 Face Masks for their advertised 97% Filter Efficiency, Waterproof Capability, Breathability and Comfort. I did receive a 40-Pack of 5-Ply Disposable Cooper KN95 Face Masks, which were divided and packaged into 8 individual Zipped Bags, with each Bag holding 5 Masks. But, while each of the Bags depicts 97% of Filter Efficiency, the Sticker on Top of the Main Package shows 95% of Filter Efficiency. I’m not sure if that was written in Error or what.Regarding the Masks: They’re made from a breathable, High Quality and Waterproof Material in the U.S. These Masks are comfortable to wear, especially near the Nose Area, where a little Sponge is added for additional Comfort. The Masks have soft Ear Straps, which appear to be One Size fit all Adults. I really like the proper Fit around the Mouth and Nose for better Protection. Personally, I don’t wear any Glasses. So, I can’t add any Information regarding any Fogginess. And the sharp Edges on the Outside of the Mask don’t bother me. As we all experienced firsthand, these Masks are not just handy for Construction Work but a Health Necessity during a Pandemic, which is why I like the Individual Zipper Bags that I can carry anywhere with me conveniently in my Bag/Purse. I highly recommend these Masks.

Because of health problems I have, I have used masks since long before covid.These are made well and the packaging is upstanding.But they restrict my breathing more than a full respirator.And no amount of adjusting/cajoling them will enable me to get a good seal around my nose.As a result, my glasses fog up with every breath.The straps pull ridiculously tight around the back of the ears, making them very uncomfortable to wear.

Never got to try these masks out. they arrived in a package that was so damaged, these masks are not usable. hopefully the seller will do the right thing and refund my money. not sure why this is a 'no return' item.
