Why did this mask fail?


Video Transcript Hey, everyone. Welcome back to the place where we're testing every single mask on Amazon, I think, because we bought this mask, the Cojin Disposable Face Mask and we can't find out where it came from, but I pretty much only buy masks on Amazon, so. A lot of times what happens is you buy something and then something else shows up, I think that's what happened here. Let's get it in the clamper and see what happens. I'm like 0 for three ... No, no, I'm one for three on clamping my fingers so far, so. Did it. Let her rip. This is a PFE machine, particular filtration efficiency machine. If you want to find out more about how we're doing this test, check out that link, but we're doing the American standardized test here. And since I don't have anything else to look at, like a listing, I'm just going to look at the box.

Cojin Disposable Face Mask. To be used by general public. Not for use by healthcare professionals. Blue side faces out. All right. Comes packaged, boxed, very standard mask. I'm sure you've seen these before. Let's do the ... okay. That was pretty good. I don't think it's gonna come off on your face, so. Let's put in on and do the smell test here. Oh, this smell is a slightly used game of Clue. In the library with the candlestick. Yeah, it smells like a board game. I think it's probably the box, but yeah, it's like a slightly used board game. Not terrible, though. Nose wire is tiny. Not used to nose wires that tiny.

All right. Let's see what's going on here. Now, remember, ASTM level three needs to be at 98% or better, but this is meeting an ASTM level one mask, which is pretty good, 97%. All in all, pretty good mask. Airflow resistant 51, 52. Cojin? I don't know how the heck you're going to buy this mask, because it just showed up magically. But if you find it, pretty good mask. 97.109. 97.109. Pretty good breathe ... Great breathability, tiny nose wire, but slight smell of Clue, but I like it. It's kind of [inaudible 00:02:31].

All right. Thank you so much for watching. I really appreciate it. And we're running a little competition right now. I'm going to put a link right there that explains it. If you leave a comment within the first 24 hours, you could be rewarded. Check it out. And I will see on the next test which, by the way, is tomorrow at 10:00 AM. We are dropping hot tracks every day until the end of 2021. So I'll see you then. I'm going to be like that uncle that won't leave after the party. It's my goal.


The Cojin disposable mask passed our particulate filtration efficiency machine test with a score of 97.11%. This blue surgical mask has 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 51.

This mask has slight cardboard smell. We couldn't find many faults with this one. The only negative is its tiny metal nose wire. 

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