Why did this mask fail?


Video Transcript Hey, everyone. Welcome back to the place where we're testing every single mask on Amazon. Today looking at Bio-th, T-H, not really sure. Not really sure about these brand names, man. All I know is that this product is not medical, and that we're going to test it.

All right, so let's put it in the clamp. Open this mama-jama up here. I like the ... Ooh, don't you hate when do you do that, where you're like, "I'm just going to open this package like a boss," and then you don't get the pull tab correctly. It's embarrassing, especially when you're doing it on camera in front of like 300 people, eventually. All right, oh, they're individually sealed on the inside. I like that. Looks like packs of five. There's 20 pieces total, or maybe 10. I'm really trying to do this quickly to get it in the cam, and then start yapping because we know this takes about a minute, twenty, or two minutes to do.

All right, let's put it in the clamp. Now, said this a million, million times, you've seen the show before, but this is not how you would do it if you're working at the NPPTL lab, which is the CDC lab. They do things a little bit differently. I just don't like messing with beeswax, so we made this custom clamp. It's a little bit different, but the results are roughly the same, which I will actually prove to you at the end of this show. How? How? Ooh, stick to the end. Unless you fast forward, of course, which I would too.

All right, let's talk about Bio-th. So on the outside of the bag here, Bio-th protective mask. Now, notice it doesn't say KN95, does it? It doesn't. It doesn't say KN95. And when I go to the listing where we bought the mask, "Face masks, reusable, 20-pack, five-ply, cup, dust." It's not a cup, it's a fold. "Face mask for women, men," women-men, all you women-men out there, "with nose wire."

Yeah, so initially I was like, "Oh, this is a KN95," because that's what it looks like, but it's not. And I can tell just by it doesn't say KN95. Let's see if I can get that camera to ... See, it just says Bio-th. Doesn't say KN95 on it. Bio-th. But it's not claiming to be KN95 either. So it's not really making any claims on the bag that I can see. Oh, it is making a claim. See if I can get this here. Cut off the dust. Cut off the dust.

All right, let's try this ear loop. Okay, not bad. Very soft ear loop. Yeah, it's not the best ear loop, not the strongest ear loop, but like, I mean ... Ooh, yeah, that's not very good. I don't think it's going to fall off on your face, but it's not ideal. Let's try it on. This smells like straight plastic, yo. I think a lot of Chinese masks have this flavor, if you will, and that's what it smells like. Not terrible, not amazing.

But does any of that matter if it doesn't protect you? Let's check out the PFE machine. What does it say? What do you say, bud? What do you say, huh? Dang guys, not claiming to be KN95, but a pretty good mask. 99.477. They're saying non-medical, they're not saying KN95, they're not making any claims, and yet, 99.477. That's a pretty good mask. What did this cost? 9.99, 50 cents a mask. That's a pretty good deal. I don't love the mask, and not my favorite, mostly just because of the duck scenario here. Not a big fan, but if that's your game, it's a pretty good mask.

All right, thank you guys for watching. I will catch you on the next test.


The BIO-th Protective Masks 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.

Where can I buy the Bioth masks
I have been using them and they work well for me. They fit better than the KN95.
