Why did this mask fail?


Video Transcript Hey everyone, welcome back to the place we are testing every single mask on Amazon. Today we're looking at the BLScode Protective Mask, Non-medical use. Don't know what BLS stands for. Maybe we will find out. Let's put this guy in the clamp. Got to open him up. Individually packaged. To the clamper cam, a little bit different setup than normal. I'll put a link to how we're doing this a little bit different than our surgical masks. This is closer to the N95 test. Let her rip. This is a PFE machine, particulate filtration efficiency. If you want to find out more about what this does, check out that link.

First of all, let's look at the listing, shall we? Not really making any claims aside from the fact that it is a KN95, which is filter efficiency equal to or greater than 95% breathable cup mask. Let's take a look at the box. The box is interesting. It's corrugated cardboard and what's cool about that is you can actually ship this box. I know that's a weird thing to point out but I know a lot about packaging now. You got the certificate of authenticity right here. KN95 protective mask, non-medical. It does say GB 2626-2019 which is the most updated standard. But they are lying because they are not following the GB 2626 standard. GB 2626 says that on the actual mask you have to write the manufacturer's name, you have to write KN95, and you have to say GB 2626-2019. Exciting, isn't it? Isn't this exciting stuff? If you don't see that on there, typically that just means that they're not following standards. Oftentimes if I find that on a mask, it's not a very good mask, but we'll see here.

Airflow resistance on this is really good. It's 102.3 pascals. Super breathable. We want to see under 150. Let's check this out. Those ear loops are plush. It's good. It's not going to break on your face, I don't think. But if I apply just a little bit ... Well, okay. Yeah, pretty good. Let's say better than average. The nose wear on this thing is insane. Let's try it on. I don't really love the KN ... Wow, this is really tight. Holy cow! It's so tight that you can actually ... Do you see? It's gaping right here. This is for a much smaller face than mine. I would like ... Maybe an older child, this would be good for. And then it's a weird ... It's wider than... It's probably because when I'm ... Look at what it's doing to my ear. That's how tight this is. Keep that in mind.

And I do the smell here. I'm going to call this smell recently sterilized ball pit. Definitely a clean smell but only one reason you want to sterilize ball pit. I wouldn't buy this just because how tight it is on my face. But again, if you have a smaller face, it might work well. Does any of that matter if it doesn't protect you? That's what this machine is here for. That's what you signed up for, I assume. It's probably not for my jokes because I tell the same ones all the time.

Woo, great! Look at that! 99.82. Wow, that's really good. That is really exceptionally good. Not following the KN95 standard, not on the EAU list, doesn't fit my face, but dang, if that fabric isn't awesome.

Thanks so much for watching everybody, I really appreciate it. We are testing every single mask on Amazon. Stick with us. If you see a mask that we haven't tested, hit me up. I got an address right below and you can send me some masks or hit me up in the comments and maybe I'll buy them. You know, who knows? I've spent like $20,000 on masks, maybe I'll spend $20,000 more. Clearly hate money. I started a mask factory. Thank you so much for watching and I will catch you on the next test.


The BLSCODE Non-Medical Protective KN95 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.

In response to K –
The standard needs to be printed on the front of the mask, not just on the box.
The mask also should have the manufacturer’s name printed on it.

The reasons given on the details page as to why KN95 masks might not be “passed” despite meeting metrics is given as “they must have GB2626 numbers on front.” Yet the image of this mask literally shows that number on the front of the box. Thus unless there are other reasons this mask type should be PASSED.
