Why did this mask fail?


Video Transcript Hey, everyone. Welcome back to the place where we're testing every single mask in the world. We tested most of the masks on Amazon, so we had to resort to new places and locations. Today, we're looking at FDA cleared masks. We're going to the FDA's website, about 100 companies that have a legitimately cleared surgical mask. Remember, masks are cleared. They are not approved. A lot of people say FDA approved and you know they don't know what they're talking about if they say that.

Let's get it in the clamper and we'll talk more about this mask. This looks like a cheaply made mask, but it's interesting. They actually included their letter from the FDA, which is cool. We'll take a look at that in this. What we did was, we couldn't buy these masks on Amazon or on other places on the internet, so we reached directly out to the manufacturer and they sent us the masks.

This is a PFE machine, particulate filtration efficiency machine. We are doing the ASTM test here. This is tested to ASTM level three, which means 98% or better. This is exactly the type of mask that we recommend. Now, these guys are pretty cool because they actually showed us their 510K letter. The Qingdao Hainuo Biological Engineering Co., which is the actual manufacturing name of the company they're selling under the brand Hynaut surgical mask.

I don't love the packaging. It's flopping all over the place. It's not very thick. I see it to be a little thicker. Wow. These are... You can tell that they're not taking a lot of pride in the construction. They're using pretty cheap materials here. And look at how this is not centered. Anytime we see that, we know that they're going to be missing something. Oh, that's pretty good though. Anytime I see just the little things in a mask when you look at it, but doesn't add up. It usually means that, oh, maybe you shouldn't trust that ask. I also don't like that I can see the nose wear. That's just me though.

I'm going to call this smell a mostly clean, clean room. Because it's pretty clean smelling, but there's just something there. I'm not exactly sure what. All right. Remember 98% or better. That's what they're claiming on the box. That's what they're claiming in their letter from the FDA. Remember, this company is an FDA listed, FDA cleared surgical mask company. Do they pass standards? That's what this machine is meant to tell.

84.237, 84.237. What's crazy is that half of the masks, literally half of the masks that we have purchased from overseas manufacturers, we couldn't buy them on Amazon. Ones that we bought, that we looked at the FDA's website, found the manufacturer, asked them for their 510K mask. And when they show up here, half of them have failed standards. That's insane to me.

I mean, that just tells you that it's really hard for the FDA. They can't police every single mass that comes in from abroad. There are hundreds of companies trying to sell to you, the consumer, and other medical consumers, hospitals. These are masks that go in hospitals and is not meeting standards. That is just absolutely mind-blowing to me.

I thought maybe one or two would fail, but it's only one or two that have been passing standards here today. All right, guys. Thank you so much. If you're enjoying this as much as I am, you should probably seek some sort of counseling, maybe talk to a friend in need. If you don't have that, there are a lot of programs available to you. I just, I don't know why anyone cares so much about masks, like I do. All right.

I do appreciate your time and attention though. And we're going crazy here. We're out there in the world, trying to find every single mask and test it. Tomorrow will be another day that we test another mask. And I'll see you then at 10:00 AM tomorrow. Same time, same bat station. Bye-bye.
