Mastodon #Science people, I come to you, hat in hand, searching for a paper.
It was about using Corsi-Rosenthal boxes in schools, but it was fairly short, because the teachers in the study school kept turning off the C-R boxes. I do not know if they used the phrase "Corsi-Rosenthal" or if they just called it a DIY air cleaner/purifier.
Does anyone know this paper?
