Thank you for doing this. I stumbled across your video while attempting to repurchase these masks. I've spent a ridiculous amount of money on them believing they were the best for my kid.
Super helpful! There are many other kids masks out there with far better filtration media, but all of them are earloop style. I was curious about this one, but for it to make sense as a purchase, the filtration efficiency would have to be higher and the pressure drop would have to be much lower (better breathability). It's unfortunate that they went to the trouble of making a headstrap style mask with a thick reliable nose wire and then ended up struggling with filtration efficiency and doing so poorly on breathability.
It's worth noting that these masks aren't designed to be worn by adults. There's not a certification process for kids masks because kids aren't supposed to work hazardous jobs, and NIOSH is an occupational organization. Also, kids are smaller than adults. Should you be testing at the same pressure as for adults? (I don't actually know, legit asking.)
