Why did this mask fail?


Video Transcript Hey, everyone. Welcome back to the place where we're testing every single mask in the world. Especially thanks to Ron, a couple KF94s that you sent me. I read this in the last one, but I'll read it again.

Lloyd, I'm assuming he's saying that, he didn't say that though, he said, "Longtime supporter of your business and the outstanding Armbruster products, as well as your YouTube channel. Thanks, Ron. Please keep up with the neat content. I need to use the word neat in everyday language more often. Neat. It's like kind of a compliment, but not exactly. It's like, aww, that's neat. It's like, neat. Yeah. I'm not going to fully commit to complimenting it. It's like almost there. I like that. Thanks for that one, Ron. I've watched almost every single mask review you've done. That's a lot of views. I haven't even watched all my mask reviews cause I experienced them in person and I was like, never again.

That's not true. I watched them before I go to sleep at night, every night. All right, today we're looking at the All Keeper KF94. We just tested the Air Queen also from Ron, thank you. And very disappointing. Check out that video, if you haven't seen it. And I noticed the Air Queen doesn't say that it's a KF94, on the packaging at least. I don't know if it is or not. This one though, right there, KF94, they're also saying FDA, with your FDA number, probably registered as a surgical mask and then MFDS. If you see that MFDS is the Korean version of the FDA. It's the one that regulates KF94. All right, let's stop jabbing about standards, open this thing up. Ooh, it's black. I love that the KF94 is typically a single pack in these like beautiful, beautiful packaging. Put it on there.

Come on, Lloyd, you got this bud. I believe in you. Clamp cam. We bought a whole camera, just for this motion here. I got it. I mean a whole camera for that? That's just excess. This is a PFE machine, particulate filtration efficiency machine, if you want to find out more about how this guy works, check out that link. We're basically doing the NIOSH N95 test on these masks to tell you what the particulate filtration is. This is interesting. This must be part of the MFDS standard. They're testing at 0.3 or 0.4 microns. Where this test is 0.3 microns basically, because NACL is about 0.3 microns. So we're not doing the Korean test. 94 means 94%. That's what they're claiming. I've never seen anything that says KF94 with the MFDs logo. I've never seen anything with those two that have tested below like 98, 99, so we'll see here.

So let's just go ahead and do this live, because I don't have much more to say about this product, except for that I love KF94s. Look at that at, 98%, and we'll get the test curve. Stayed right above 95 the whole time. Airflow resistance is 215. That's a little high. It's going to be hard to breathe in, but you know, that KF94 style gives you a lot more breathable area. So that does leave a lot of room for air in that. I think this is going to test really well. May make it to 99. Are we going to do it? Is it going to happen? Is it happening? Is it happening?

No, just missed it. It was just over the edge. Oh well, it didn't happen. See, it could have been... Right? Wouldn't that look so much better? You couldn't tell. Awesome. Can I zoom in? Useless. All right. 98.981, 98.981. Pretty good test. Let me open this guy up. I only have one. So I have to be careful about trying this thing on. Oh, that is like, I'm going to call this smell back room of a clothing store. Yeah. It's like a fabricky type smell, like a lot of fabric going around. Good construction. I've seen better nose wires for sure. And the ear loops are nice and soft, but I don't know... That's pretty good. That's not going to come off your face. I think if I, yeah, it broke. I kind of expected that, but pretty good. Like not the best, not the worst. All right guys. Thank you so much for watching this.

Really appreciate it. Appreciate your time. Appreciate you, Ron from New York, watching this and sending me your mask. That's great. If you like this video, do me a favor. Give me a like or a subscribe or be like Ron. Send me some of your masks that I haven't tested yet. That would be really, really neat. All right. Thank you so much for watching. I will catch you on the next test.


The All Keeper KF94 mask passed our particulate filtration efficiency machine test with a score of 98.98%. KF94 masks are boat-style and made in Korea, which has very strict production guidelines. All KF94 masks have ear loops instead of head straps or head 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 218.54.

This mask has an inoffensive fabric odor. With its high airflow resistance score, It's going to be hard to breathe in, but KF94s do offer more breathable area. The overall construction was rated good.

Someone sent us this mask for testing. Check out our video review for more details.
