KF94 Certified Premium 4-Layer Black Face Mask [Adjustable Ear Loop][Anti-Trouble Skin][Made in KOREA]

This review compares several different masks that I’ve purchased; both surgical and KF94. I’m hoping it will help others make a decision. I wear glasses and am in New England, so I will be giving their ability to not fog my glasses extra credit.First, I’ll cover the surgical masks. Unfortunately, the best surgical masks I got were from Harbor Freight before the pandemic, they had a real, large, wire in the nose, new ones from Harbor Freight do not. Now all of them have twist tie wires, i.e single small gauge wire with a flat plastic coating. Bend a twist tie around your finger and see how well it stays, it will bounce back on you. I’ve purchased Hatrigo Class 1 and Comix. The Hatrigo masks have a weaker nose piece that won’t keep their shape, so I won’t be getting those any more. I found Comix Disposable Face masks hold shape better; but, the second batch I ordered wasn’t as good as the first batch in terms of fit.Second, I’ll cover the KF94 masks. I haven’t cut open most of these and the reason they hold better on the nose is because they have 2 larger gauge wires with the same flat plastic coating. So two larger in KF94 vs one smaller in the surgical masks. The Care ON basic KF94s collapse when you breath in, i.e., they aren’t stiff enough to hold their boat shape. This makes them difficult to breathe through. The nose piece is ok, but not great. They are also smaller in shape. LG Health Care Airwasher KF94 is larger and has a stiffer nose piece but is harder to breath through than the next two I’m listing. It does keep its shape when you breath in. It also has adjustable ear loops which helps. The BOTN/TIA in black holds its shape when you breath in and is easier to breathe through than the Airwasher. Otherwise, it’s about the same. Also has a good nose piece but neither is perfect for stopping fogging in cold weather. Bluna Face Fit to me is the same as the BOTN/TIA in most ways; keeps its shape when you breath in and decent nose piece.Mask Lanyards. One thing that really helped with the overall fit is buying a Mask Lanyard, I bought a set from TEKcians. They allow you to put the loops around the back of your head instead of your ear, which allows the face mask to fit MUCH better. It allows the following combinations: 1. both loops above the ear, 2. one loop above the ear and one loop below (but not pulling at the back of the ear anymore because it’s tight around the back of the head, or 3. both under the ear. The both under the ear may be the best for preventing glasses from fogging but it also puts a fair amount of pressure on the bridge of your nose. These lanyards are slightly stretchy which helps with pulling them onto your face, and you can adjust the length easily.I hope this review helps.

This mask is the genuine article. It is sturdily built, can conform to a smaller adult face, and finer adjustments can be made to assure a decent seal with the earloop pulls. The bottom of the mask has a bit of material which cups the face underneath the chin to minimize leakage and help to hold it in place so it is unlikely to slip around. The metal clip in the nose bridge feels thicker and extends wider across the top of the face, so that it does not lose form easily once pressed against the nose and closes off those cheek gaps that most other masks leave very open. Half masking will NOT happen accidentally in this one! The extra strip of material across the front provides thickness and keeps it from collapsing against your face as your breath. It looks pretty cool too.On the downside, it's a bit stuffier to wear than a lot of the surgical style masks -- but that is because you are getting MUCH better protection!The reason I bought it is not so much COVID related (I'm vaccinated...so not too worried about that) but because I wanted an alternative to the N-95s (which must be strapped to the face from the back) which is a little less cumbersome but is still decently protective for issues such as fine dust and debris, wood cutting, etc. I was impressed with how the mask performed in some independent technical reviews online, and I must say the seal feels as good as some of the generic N-95s I've used over the years. If I WERE concerned with protecting myself against COVID, I would definitely feel a lot safer with this between me and the outside world than most other masks out there.

I have tried a number of KN95 and KF94 masks and this is my second favorite mask only barely edged out by the LG Airwasher KF94 black because it has a stiffer nose wire.I decided to try this mask after reading Aaron Collins' mask reviews on Youtube. He is a mechanical engineer who has experience working with aerosols and does very detailed tests on filtration efficiency, pressure drop (ease of breathing) whether the mask collapses while you breathe in, and the overall quality of the mask. He also shows his raw test data.The things I like about this mask are that it's boat style so stays away from your mouth. It fits me well, it has adjustable ear loops, is comfortable, and is easy to breathe through. It has over 99% filtration efficiency, per Collins' tests, and appears to be very well made. Oh, and it's black so it looks cool.Of course, a mask is only as good as its seal and everyone's face is different so YMMV.

This mask is very comfortable because of the adjustment ear loop. But there was no gray lanyard included with my order.

This is on the FDA approved list of non-fraudulent imitations. (South) Korean made is the key.It is the FIRST mask that we have tried that does NOT FOG GLASSES. I also realized just how terrible my breath is--because the air does not escape. The ADJUSTABLE STRAPS are awesome for a tight fit. The nose piece is high quality. These fit small and average sized faces. They don't press up against mouth or nose, so there is less a sense of claustrophobia. They do have a bit of an odor--something I think we all have to get used to. We air ours out before wearing. No skin or eye irritation for my family.

If you cant get N95 (which most of us can't), try these. Like one of the other reviewers, i also bought these based on an article written by an engineer who tested a bunch of masks, and he recommended these, among others i think. They are pricey, but they seem to fit rather well, particularly the ear loops. which do not pull my ears out. Also, i can breathe reasonably well in these. Finally, anything with ear loops are difficult for someone who wears hearing aids, but these are the best of the ear loop version that i have tried
