Great work, thank you for sharing it with the world.
I am very curious about country stats and have 2 questions.
First, I found this one randomly: https://www.armbrustusa.com/blogs/mask-review/kf94-try-mask-kn-flax-boat-adult-regular-black-658 https://www.armbrustusa.com/blogs/mask-review/kf94-try-mask-...
The country of origin on your page says China, but the photo's box says Korea. Is this a mask repackaged and exported from Korea that is actually from China?
Second, does "China" also include Taiwan? If so, I would be interested in separating them for statistics.
for those interested, here's a first level breakdown of pass/fail by country
| country | # pass | # fail | pass rate |
|-----------+--------+--------+-----------|
| USA | 39 | 27 | 59 |
| China | 48 | 186 | 21 |
| Korea | 31 | 13 | 70 |
| Thailand | 0 | 2 | 0 |
| India | 2 | 12 | 14 |
| Mexico | 1 | 0 | 100 |
| Germany | 0 | 1 | 0 |
| Singapore | 1 | 0 | 100 |
| Vietnam | 1 | 0 | 100 |
also, in this dataset it looks like adult masks have a 66% pass rate as a whole, while kids masks have a 73% FAILURE rate!
So a third question is, are you using adult mask testing methods for testing kid masks as well (which would explain the failure; on the other hand, the kid masks that passed must be quite some mask!), or do kid masks just suck in general?
- lloydarmbrust 5y agoAh! You caught a mistake. Thank you it's fixed. China and Taiwan are separate (they make very different masks) but I haven't been able to find any from Taiwan to test.
- nobodytoseehere 5y agothanks for the clarification! (apologies, I edited my original message with a third question, which I would love to get an answer to, but now I don't want to mess with this thread anymore)
- lloydarmbrust 5y agoIn the US the standards for adults are the same as kids... in China they just came out with a new standard but for reasons I wont go into we don't cover it (very China specific). That said, I have also noticed this... if a manufacturer in China makes a great adult masks, their kids mask is likely to fail standards for filtration AND be harder to breath. Having made both adult and kids masks I can tell you that there is way less of a demand for kids masks and because of that less attention gets paid to them on the manufacturing floor. Theory: People are just lazy and make worse masks for the kids I think because kids are not paying attention. Furthermore, kids don't care that it passes standards, they care if there's a dinosaur on the mask or not. Even my own kids tell me my kids masks are boring! So manufacturers put their time on making it fun and not on protection. We test both kids and adults to the same standards, use the same fabric, etc. Boring but effective :)
