(Pack of 10) Good Day Korea Black Disposable KF-94 Face Mask 4-Layer Filters Breathable Comfortable Protection, Protective Nose Mouth Covering Dust Mask Made in Korea.

Upon receiving these I ended up getting to try one for the first time when I had to go to Urgent Care for a COVID test. They fit my face perfectly, but I had no room to spare. I could see if you had a larger face/jaw fit could be a problem. This is the first mask I've had that DID NOT FOG MY GLASSES. At the same time, when I was answering questions (or just breathing) I could feel that humid air from my breath on my face, so the seal must have been pretty decent. The ear loops were absolutely the most comfortable yet, even better than the adjustable loops I have on my cloth masks. The masks fits away from your mouth, so if you want to wear lip gloss or lip balm, you don't get it on your masks! I loved these so much, when I got home I bought another 10 pack!

I went through a ton of masks before I found the right KF94 fit, which is this particular one. It's still a little snug but isn't too hard to breathe in; fits over my face; and feels sturdy.I also like that it's all individually packed in its sleeve so you know it's clean out of the box. The strings aren't adjustable, so that is something to definitely be mindful of when buying these particular masks. However, what I found with the adjustable strings on other masks is that my ears can't take double-looped masks (the strings eventually slide off my ear) and I had no trouble here with the Good Day brand with the string coming off.Again, it's worth doing a bit of a test trial to see if it fits, but again, for a medium size guy's face, it worked great and is my go to KF94 brand.

These fit very well and comfortable on my thinner face, which I've struggled to find proper fit. I especially like them being individually packaged as I travel regularly and can stash these in different bags and they stay in shape, clean, and protected. I don't find them at all uncomfortable or hot on my face.

These run small. I'm an average size male (mostly) and these are running small. I had to pull on the starps almost to breaking them to make the mask comfortable.

This is my favorite mask. Easy to put on. Fit's your face and offers better protection than most.

I find these masks to be more comfortable than cloth or surgical masks, and I think the solid black makes them more subtle and "cool" than other masks as well! It kind of looks like you're wearing a hard plastic mask, I think.KF94 masks have good performance in preventing COVID-19 transmission from the few articles I've read. I got KN95 masks as well, but apparently a study showed that about 70% of them don't provide the full advertised effectiveness. I think South Korea may generally have better quality control than China, but I haven't seen any actual evidence, so it's more of a guess than a fact. Regardless, N95 masks are incredibly difficult to buy, so for general use outside of medical facilities, the KF94 seems like a good way to go.One last important piece of information! Know how these are used and what their limitations are. I saw a study that I believe said HEPA respirator/masks (i.e. KN95, KF94, etc.) can become less effective after being saturated with moisture from breathing (i.e. after be 4 hours, I think?), so you may want to consider the limitations based on the situations you'll find yourself in. If you are in a high-risk group or will be in high-risk areas, it's probably best to do a bit of research to be confident in what PPE you choose.Best of luck and stay safe!

As per some other reviews, I also found these masks to run small. They would probably fit my 13 year old granddaughter. They seem to be well made if you are ok with a smaller mask. I am female with an average size head and face and I found them to be too small for me to work. 7 3/4" long, 3" wide when closed. the flaps that open to go over your nose and under your chin are only 1 1/2" wide. I think that is what makes them fit too small. This part should be a bit wider.

I like this style of mask where it does not touch my lips. It fits comfortably, it does fog up my glasses but that is not a huge deal to me. Not sure how many layers this mask has but it is pretty light weight and thin, very breathable. Only con I have is that the wire for the nose bridge is not very pliable, it’s too weak that it won’t keep the shape of my nose contour.
