Video Transcript Hey, everyone. Welcome back to the place where we are testing every single mask in the world. Even the ones without names sent to me by Peter, from Brooklyn. All right, Peter, let's do this. Let's check this out. So this one is very interesting.

Sure, blur out Peter's address there. It's very interesting. "Dear Armbrust, I really enjoyed your YouTube videos. Here's a box of KN95s you might find curious to test", question mark. Peter, you're right. I am. "I bought these masks in June 2020 when KN95s became near impossible to find. At some point, I found some other masks and put these KN95s aside." Probably a good idea. "I've always wondered though, did it receive the advertised filtering?" Thanks in advance, Peter.

All right, Peter. I am also curious because it's basically illegal to have the stand... To follow the GB2626, which is the Chinese KN95 standard and not put the manufacturer name on the box. There's no manufacturing name on this box. In fact, when we first saw this, we said "Is the name of the manufacturer ergonomic design? I don't think so." All right, let's open this up. Made in China. These are just flopping around in here. There's no quality certificate. So part of the GB2626 standard is that you actually say that on the mask itself, I believe. So the fact it doesn't say that on there, leads me to believe this is probably a fake. It just says KN95, I wouldn't trust it. All right, let's go ahead and get this in the clamp. It's a little bit different test. This is the KN95 test.

Same test that Nayash uses, except for we're not using beeswax. That's right. Beeswax is part of the KN95 or the N95 standard. In there. This is really a lot more simpler for me to load and should get approximately the same results. Right? So let a rip, is a PFE machine. Particulate Filtration Efficiency machine. We're doing it a little bit differently than we do with surgical masks. We're using NACL instead of latex particles. If you want to figure out more, putting a link there, talk about the different setup. Right away, I'm seeing that the breathability is super high for most KN95s are 164. So interesting... Interested to see what it actually performs at. You know, normally I'm like looking at their website, I'm trying to figure it out, but there's really not a lot here. Always got is the box to go on. Made in China.

It's not even saying that it's... Oh, wait, production date. So it may have... Oh, okay. Product material... No, I thought for a second, maybe in Chinese here, my Chinese friends, maybe you can translate that for me. It could be the name of the company, is there and we're just missing it. 'Cause it's got the batch number in the production life. So pretty standard design. If you look at it, ear loops not good. A lot of KN95s, it's really hard to get the welds right there. A lot of times this will come off. That's pretty good. That's not bad.

And this was an open package. So I'm not really sure that testing the smell is going to be fair in this case. It's a pretty good quality mask. And when you look at the results, surprisingly, even though there's like no manufacturer name or anything, they made a good mask. Efficiency, 99.356, 99.356. So Peter, yeah, lucky on that one. Weird that they're, I think not following the full standard of KN95, but they made a good mask. So there you go, you were pretty well protected. All right. Thank you guys so much for watching this. I hope you enjoyed the review of the generic KN95. If you can figure out what this brand is, let me know. So we can put it on our website. Otherwise, I don't know how useful posting this is going to be for other people. I guess if it looks exactly like the box, maybe you can find it. If you can figure this out, I'm actually very curious about that. All right, I will catch you guys on the next test. Thank you so much.

The Generic KN95 Non-Medical Protective Mask failed because the KN95 standard requires that the mask have the manufacturer’s name and the appropriate technical standard, typically either "GB 2626-2019" or GB-2626-2006,” written across the front of the mask. This is similar to how official N95 masks display NIOSH approval numbers. This mask did not have the required identification on its front.
