#22Don't see any of the masks I've been buying off Amazon for a while:
https://www.amazon.com/gp/product/B08H3WDXMS/
https://www.amazon.com/gp/product/B087Z7N4XF/
Maybe because not sold by Amazon directly?

#23How does one verify whether the product on Amazon is legitimate? Most masks have reviews referring to comingled fakes, and it's put me off buying.
If it's on Amazon or eBay, you have no way of knowing if it's fake. Buy directly from a distributor such as https://www.projectn95.org, https://bonafidemasks.com, etc.
If you prefer the KF94 types, I've heard good things about https://kollecteusa.com and https://behealthyusa.net.

#24Not exactly surprising that a majority of the "fail" masks came from China.

#26Consider adding (affiliate) links to ones that did well, ordered by availability or price. Why Amazon doesn’t do this is beyond me.
I had wanted to do this.. cause, money... but I felt that took away our credibility.
For a random consumer opinion I dont think collecting marginal payment on sales leads hurts credibility per se. The huge red flag for me is taking payment from manufacturers. But an adequately disclosed commission, applied equally to different masks, doesnt obviously introduce bias in to your test results. I guess it could induce you to recomend higher priced masks. But readers have the qualitative data available to select comparable, cheaper, products as well.

Perhaps you could provide two links. Once with affiliate tag and one without? Give users the information and the choice.

Especially since the majority of masks come from China.

#29@lloydarmbrust ,
I’m curious about the fail rating for masks where Standard = KN95 is fail? Specifically for masks that claim to be KN95 and filtration values are high. How do you determine a failure here?
Just curious. I think this work is amazing.
