KN FLAX - Face Protective Mask (White) [Made in Korea] [10 Individually Packaged] 4-Layers Premium KF94 Certified Safety Mask for Adult [English Packing]

I purchased these after spending many hours researching the FDA and CDC's NIOSH sites and data. I am so happy with this purchase! I've had a problem with "normal" masks being too long, too large, unbreathable, un-sealable, and/or too stupid-looking. (No thank-you duckbills!) Of late, I've been wearing a blue surgical mask with another lightweight mask over it, but -wow- it was so difficult to breathe in the summer heat, yet the seal was never really good. I finally realized that I have a smaller face then most other people and there was probably no way I would ever find a great filtering mask that fit, without looking completely ridiculous. Then, I read an article in wirecutter, which explained various (brand) mask properties, including whether the brands/masks were CDC NIOSH or FDA approved. The article specifically mentioned this brand of KF94: (quote) Like most KF94s, which didn’t arrive in the US market until later in the pandemic, Kyungin Flax hasn’t undergone the process for NIOSH approval or FDA clearance. So, in collaboration with Colorado State, we filtration-tested the mask ourselves—and found it to block 99% of particles as small as 0.5 micron. (end-quote) That was definitely good enough for me! The strange thing is that the article said this particular mask may not be suitable for someone with a small chin. Ha! Wrong! When the masks arrived, I immediately opened one and put it on. OMG, amazing! This mask has a more structured “boat” shape (a horizontal rectangle that tents up to secure itself over the nose bridge and chin) and gives a more-reliable clearance over the nose and mouth. i.e. More filtered air to breathe in. The ear loops are a bit too long, but that's not a deal-breaker. i.e. Just knot them or use the enclosed small s-type clip to pull the ear loops to the back of your head. (Amazon has some great, light-weight lanyards, as well.) The adjustable metal nose clip is flat (hate those thin round ones) and is about the same length as on my KN95 masks. Note: According to wirecutter... Overall, most KF94s feel thinner than the N95s and KN95s. But, they are comparable in feel to the highly rated Kimberly Clark N95 Pouch (duckbill) Respirator. That said, in comparison to my KN95 masks (bought on Amazon), this Kyungian Flax KF94 mask feels thicker. This KN Flax mask gave me the best seal and comfort of any mask I've tried. (16 months into the pandemic, I've tried a LOT.) It is lightweight but sturdy and actually looks great. I highly recommend this mask!

I can’t believe I am writing a review about a mask but this one works great. I have been able to wear this mask without feeling suffocated for many hours and since I have health issues this is a must for me. I tried the blow out the flame with this mask and I could not so I think it is thick enough to protect me. I is very comfortable and I have a fat face and it is not too tight. I like that it folds flat so I can keep it in my purse of pocket when not using it. The wire seems to work well but when I don’t have set right my glasses do get fogged up until I adjust it then it works great. It snugs the face really well with no gaps. And the design gives you plenty of room around the mouth area. I have bought KN95 and cloth and I like these the beast. The only other I like are the cone shape KN95 but they done fold away and are bulky. Stay safe everyone.

The mask is comfortable, did not irritate my skin , it is a bit loose on me so I just give the ear piece a twist over the ear, add a surgical mask for additional protection and it’s fine. They came well packaged and faster than expected. I feel this mask offers good protection and the price was fair. I am a retired RN and I feel safe using this. I do have a real N95 from when I worked, fit tested and all and I could easily use it but it’s so uncomfortable. For the little amount of time I’m out these days this KF94 is fine. I would recommend this mask.

I love this mask! Wish this existed from the start! It came in individually sealed packages. It smelled a little when I first open the the sealed mask package. But it went away fast. I have to do physical therapy almost on a daily basis and I can never breath well with the normal mask. And those mask always gets wet. But this masks has enough space away from the nose so the mask stays dry and the most important part is I can finally breathe in therapy! I also love the ear loop instead of the 2 elastic strap I cannot put it on with one hand! When I unfold this mask the top 1/3 goes over my nose and stay well and I have a really flat nose the middle 1/3 tops out yo allow more breathing space and the air to come in when I take a breath. The bottom 1/3 flips under my chin and stays put! So comfortable and effortless to put on and stay in place through my therapy. Even with my flat face it doesn’t move up and down my face when I talk like the other masks!it’s just a well made and functional mask! It’s soft light weight yet strong and no nose tickling mask! I love love love it!

EDIT: I read thru many Reviews after the fact that we really like these for the Breathability. Dr Oz told us all how to test bought N95 Masks. FILL THEM WITH WATER AND IF THEY LEAK THEY ARE NO GOOD FOR PROTECTION. This Mask PASSED the Test...as well as it didn't get wet. And a note to the size, my Hubby has a large round face/head and He still LOVES this over all the other Masks. Fits him snug, me not as snug. Took a chance on this order....as we all do with unknown stuff on Amazon. BUT HUBBY SAID These are the most comfortable, and do not impede his breathing. WOOHOO...said they are comfortable and the best he has worn. And mind you....I make/made our Masks. Yuuup. So much for making him anymore Homemade extra protection, nose bridged, filtered, masks. I am done with that nonsense. These are his Favorite. He also has really bad lungs from Double Pneumonia then single pneumonia again in one lung. His lung capacity is about 30 percent. YES THESE MASKS ARE EASY FOR HIM TO BREATHE THRU....He is Happy.

Many people buy cloth masks with nice designs or logos. These masks are great for protecting others but they do little to protect the person who wears them. You know this intuitively because the fit is not snug and air seeps through all around the top and sides. Similarly the blue paper disposable masks that you see everywhere are great for protecting others but they don't do much to protect you because it is easy for droplets to penetrate them. Similarly the Chinese made KN95 masks do not fit well (poor quality control) and thus do not protect YOU. These KN94 masks were recommended by medical professionals in a recent NYT article. They are made to spec in South Korea where they have been used for years to protect YOU - the person who wears the mask - against the flu and other ailments. You know this as soon as you put the mask on your fact because the seal is tight. The mask seals tight on your face, which means that it will be difficult for COVID droplets to go around the sides of the mask. The mask is made of flax which is also better at stopping droplets than those cheap blue paper masks and cloth masks. This is the only mask that fits so tight that my sunglasses do not immediately fog up when I breath out. That's a sign of a good fit. The only better masks are the N95 masks with vents that are made by 3M. They have a super tight fit because they use two loops around the back of your head instead of the ear loops. Unfortunately those 3M masks have been impossible to find since the pandemic began and many airlines do not allow them due to the vents. So do yourself and your loved ones a favor. Stop buying cheapo paper masks made in China and spend a few $$ more for these high quality masks. You will see the quality difference as soon as you open it, and it may save your life.

I was shipped the gray color, but wanted the white. That's why I gave it 3 stars instead of 5, because it is a great product. The pictures showed it was gray but in 2 descriptions the details described them as white. The last ones were white and I liked them very much. They are easy to apply, comfortable and I believe they protect my face well when fitted properly with tying a knot on the ear loop for the large because I have a smaller face.

This is the best mask I've tried for wearing with glasses. The nose bridge is comfy and easy to mold to your face, and once it's adjusted it feels like it creates a pretty good seal while still being breathable. It doesn't 100% solve the glasses fogging issue, particularly in wet weather, but it's much, much better than cloth or surgical-style masks. Highly recommended for my fellow foggy glasses sufferers. Caveats: overall I find it comfortable to wear, but because the inside is a plasticky material, it doesn't absorb moisture and becomes swampy and wet with condensation over time. It's bearable for an hour or two, but might be gross to wear all day. The ear loops aren't adjustable and are made of a soft but cheap-feeling material that I suspect will be the first failure point of the mask. I usually twist them before putting on to get a slightly tighter fit. I have no idea whether this mask is an authentic KF-94 or not, but it seems high quality enough that it's become my go-to mask for activities like grocery shopping or riding the subway.

Son cómodos y útiles para realizar las actividades cotidianas.

Calidad y comodidad excelente.

De buena calidad

En la descripcion dice "Hecho en Corea" y cuando llego, el paquete dice "Hecho en China". Busqué en particular a proposito mascaras DE COREA porque son reales, garantizados, y estas no son, estas son una version pirata no reguladas. Aparte están hechos chuecos y chafas, y a los 10 minutos de ponerme una, se rompió. Ahora pasar todo el lio de la devolución, es muy aghghghghgh. No mientan en sus descripciones, por favor!
