sure, this was a helpful less-scientific study: https://cleantechnica.com/2016/07/09/home-indoor-air-quality...

and this is the study that foobot themselves reference: https://cdn-foobot.pressidium.com/wp-content/themes/foobot/a...

Definitely seen these studies. I think they are from a few years back though, so the relevance might be in question. I don't think the newer versions of laseregg, netatmo, awair, or any of the other leading brands are on there. What I love about that study (and find funny) are the A-F ratings. If you look at the averages... both foobot and awair have the same grades (2 As, 2 Bs, and a D), yet one of them gets an A and other gets a C.
