KN FLAX KF94 Masks For Adults - Face Protective Mask (White) [Made in Korea] [20 Individually Packaged] Premium KF-94 Certified Face Safety White Face Mask Dust [English Packing]

I've found these to be the best fitting most comfortable mask I've tried. Love the individually wrapped packets. Makes it easy to keep a spare or two in the car when I forget to grab one.The nose adjustment built in is effective but much more comfortable than the harder metal ones on some masks that cut into your nose. It is firm but well padded and comfortable.The over/under design really makes for a snug fit. I can really feel the slight resistance all around as I breath in so I know what I'm breathing is being filtered. That said it doesn't collapse in my mouth or feel difficult to breath at all. And very little air escapes the edges when I breath out. Glasses still fog a little but less than other ones I've tried.I've found these much more comfortable to wear and breath through for long periods of time.It would be really nice if the US government would do their job and properly identify masks that meet the best international standards. It feels like these meet an excellent standard, but it would be nice if someone could certify these supplies!In the meantime I hope my anecdotal experience was helpful. These are the only ones I'll use till the pandemic is over for going indoors to places like stores where there will be a lot of people inside.

Comfortable wear, excellent protection

Okay, first off, I do find the masks comfortable, but there are a few concerns.The pack I received (20 masks) came with 2 plastic clips. They are fairly cheap, and I don't think 2 of them will be enough to get me through all the masks I ordered. When I use the clip to fasten the straps behind my head (rather than using earloops) it is a fairly good fit. Certainly better than a regular (non N95) mask. If I just use the earloops, though, it is way to baggy and saggy. I'll have to come up with ideas for how to handle that when I break or lose the clips that came along. (I'd be much happier if each mask had a clip.)They do come separately wrapped, which is nice.But the masks are really thin. I'm going to cut one open, but even if there are technically 4 layers, they are thin layers.They also have an odd scent to them. Not uncommon with masks, but since it is smashed up against my face, it's worth mentioning.I really wanted to try this style/shape of mask, and I'm not turned off completely. I think they are much more comfortable than N95s and much better fitting than regular surgical masks. How effective they are, though, IDK. Like I said- they're pretty thin. I will likely double mask when I use these masks indoors. I'm just not super confident that they are going to provide the level of protection I'm looking for. I might try another company with the same style/shape and see how they measure up.

Not bad, this product is very good.

I used these while there was a lot of wildfire smoke in my area. They fit well, the smoke was filtered out, and my glasses didn't fog up.

The KN FLAX KF94 masks are fantastic—they fit securely yet comfortably and provide excellent coverage. The four-layer filtration system gives me confidence in their protection, and they’re breathable enough for extended wear. I also appreciate that each mask is individually packaged, which makes them hygienic and convenient to carry. Highly recommend for both everyday use and travel!

Edit (12/23/21): Removing 1 star from my original 4 stars, as I have to fix the ear loops to my ponytail, otherwise it really hurts the top of my ears after a couple of hours. Also, no matter how firmly I fix the mask against my face, it does not create a good seal, and my glasses fog up horribly.Original Review (11/25/21): Now that I'll be back working at the office, I've been trying a few different types of disposable masks to find the most comfortable to wear all day.These fit the bill nicely. I wore it on a 2 mile fast paced walk around the park to test it, and they were comfortable and easy to breath in even when I was huffing and puffing going up a steeper hill.In case someone is thinking about wearing them during exercise, be aware that it did create some condensation on the inside from hard breathing, which felt icky when my chin or lips touched the mask. But for wearing sitting at the office, they're perfect.I particularly like how they are individually wrapped. I can keep a few in the car or at my desk at work, and they won't get dirty or contaminated.My only complaint is that they are a little on the large side and fit loosely around the face. But the company provides you with a couple of plastic loops to pull them behind your head instead of ears, and that makes it fit snugly with a good seal.

Comfortable mask, that makes a good seal and gives good protection.
