Why did this mask fail?


Video Transcript

Hey, everyone. Welcome back to the place we're testing every single mask in the world. That's right. Today, we are looking at user submissions, which is really exciting. We've got my N95 setup so we're doing the NIOSH style testing, which is a little bit different. I can explain in a link up there.

And this mystery user, mystery viewer, who I'm pretty sure is from Washington sent me a bunch of masks to test. This is the last one. This is from Outdoor Research. So Outdoor Research, I think they're actually based in Seattle, probably just down the street from wherever this person is. And it looks like they got their NIOSH N95 on this. So pretty excited to look at this. They say it's made in the United States. Actually don't know much about this company. I thought there were more of a brand. This is a KN95 design.

I'm actually pretty surprised that this was able to get NIOSH without a nose foam on it. So typically you need a nose foam to get that extra seal on there. So that's pretty interesting. And then also the staples, as you can see, go right through which I can actually see the holes, which means there would be some leakage there. So that is very interesting, but it's got the TC number. I'm looking on their website. So it does appear that they do have a 95.

Without further ado, let's put it in the clamper. My clamp cam is damaged at the moment. Not really sure what happened there. This is a little bit different setup than before. Like I said, you can check out how this differs. We are doing a slightly different test than what NIOSH would be doing. And really the big difference is how it seals around the mask.

Let's let her rip. There's a PFE machine, particulate filtration efficiency machine. I'll put that link one more time if you want to find out how this setup works. Okay. Let's take a look at this. I like the way this looks. I've seen a lot of this. I like that they did the staples. That is usually a much better... Wow. That ain't going anywhere. Holy cow, you could hold up 40 pounds of Starbucks beans with this. They're from Seattle.

Let's try it on. Again, I appreciate whoever sent these to me, but if you're going to send me... Wow, that was a great mount. Great mount Lloyd. Is that how you put a mask on? I don't even know. If you're going to send me these, please send me in the box so that I can verify the box and label and all that. I don't like the way this smells. I'm going to take it off. It was just sitting in the bag though. So I don't know if that has anything to do with it. I'm going to need to buy some of these now to really test them, to see how good they are. But yeah, it was really tight on my face. I don't like the way that it feels and I need a little bit more head strap. It was like a little bit too tight for me, but man, that's very strong. Seriously, that's the strongest thing I've... Ow. That hurt. This is the strongest ear loops I've ever seen for sure.

All right. Let's switch over to the PFE machine, see how we're doing. So look at this. I mean airflow resistance, 103. That's insane. We've seen that before. We tested the Indiana face mask, also American made mask. They were sub 100s with their flat fold design or KN95 design as I like to call it. And yeah, I mean, great efficiency. So great fabric. This machine tests just fabric. It doesn't test the fit. We're not really testing fit here and you need both. You need fit and filtration for a mask, which is why for an N95 I like to see that extra nose foam. Also helps with comfort on this. All right. Final survey is 99.602. 99.607. I'm looking at it. I'm saying the wrong things. No one knows what's going on. Look, it's like two o'clock on a Friday. Give me a break.

Thank you for joining me. And you know what? I haven't asked for a while. Give me a like or subscribe or not. I don't actually care at this point. Thank you guys. I'll catch you on the next test.



The Outdoor Research N95 flat-fold respirator mask passed our particulate filtration efficiency machine test with a score of 99.61%. A defining characteristic of N95 masks is they have either head straps or head ties (no ear loops). 

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 104.56.

This mask has a strong odor and a fit that's uncomfortably tight. It appears to have received the N95 certification from NIOSH without having nose foam, which allows for a better seal. Leakage could also occur around the staple holes.

Someone sent us this mask for testing. Its country of origin is the USA. Check out our video review for more details.

I was sad to find out these are not earloop N95, but instead the usual over the head straps. Has Armbrust tested and/or found any good earloop N95’s made in the US?

Checked with the OR company directly, definitely NOT ear loop style. “Head harness secured”.

KWilliams February 24, 2022

Correction please, you label it as ear loop strap and the box shows over the head strap.
