Why did this mask fail?


Video Transcript Hey, everyone. Welcome back to the place we're testing every single mask on Amazon. Today, we're looking at a lot of KN95s. Very excited to look at the Ryeziio mask. (singing) That's interesting. So it two I's here and then on here, it's got three I's. Which one is it? Which one is it? Pick a lane. All right. Let's open this up and see. Well, attention to detail with these guys, for sure, huh? Okay. You open it up and then it's individually pack it, it's packed in fives. Oh, this might actually be a legitimate KN95, which would be the second one of the day.

I'll tell you how, if you're just joining me for the first time, I'll show you how I know that. Clamp cam. Good clamp. Let her rip. This is a PFE machine, particulate filtration efficiency machine. If you want to find out how this works, check out that link. We're doing the NIOSH test here, which is the test they used for both N95 and KN95, which is important. So why did I say that this thing is probably a legit KN95? It's just a simple little test that you too can do at home. So the KN95 standard requires three things. You got to say K95, you got to say the type of KN95, so they have this standard. This one is the GB26262019, and then you got to have the manufacturer name, Ryeziio. I don't know why they got it wrong on Amazon but that seems to be the manufacturer's name. So that's really cool. This may be an actual KN95, so very excited for that.

Let's take a look at the listing really quickly. Black KN95 manufactured by, well, that's interesting. Guangzhou Powecom Labor Insurance Supply Co. What? That's a pivot. What are insurance supplies? What is that? Was this a random name generator? Insurance supply, labor, specific types of insurance. Man. I see why they went with Rio. It's just much easier to say, although technically that's not the manufacturer's name. All right.

Let's check out the ear lobes. Those are pretty good. Those are pretty good. Let's try it on. Hmm. This smells like the lint inside of an old jeans pocket so not horrible, because it's been washed, but just interesting that a mask would smell like that, but it doesn't have the traditional super plasticy smelled that masks have. What was the breathability? Did you catch?


114 pascals, that's great breathability and yeah, does any of this matter if it protects you, right? Does it matter if they are insurance supply company, whatever that is. And they made a great mask. 98.474, 98.474. Good sturdy mask. Mostly, I'm going to call it following the KN95 standard, which is the second one that we've tested today, which is ... Actually the second one I've tested, ever, I think from Amazon is actually quasi-following the standard and it has 98% filtration.

So, hey, Powecom Labor Insurance Supply Company, you make a great mask so that was a good pivot, good pivot. You guys did a good job.

All right. Thank you guys so much for watching this, hope you enjoyed it. If you did give me a like, man, or subscribe at it, I'd appreciate it very much and I will catch you guys on the next test.


The Ryeziiio mask passed our particulate filtration efficiency machine test with a score of 98.47%. All KN95 masks are flat fold and have ear loops instead of head straps or ties.

Mask breathability is determined by airflow resistance, which we measure in pascals. The target for adults should be around 150, and the target for children should be close to 100. The airflow resistance of this mask is 114.

This mask has detectable odor that was compared to pocket lint. It, however, received high marks for its sturdy construction and breathability. 

We found this mask on Amazon. Its country of origin is China. Check out our video review for more details.
