Germicidal UV: a tradeoff between disinfection and indoor smog

A Substack (blog) post with a first estimate of the magnitude of the tradeoff.

TLDR: still uncertain, but GUV smog is likely to be a significant concern, needs to be carefully evaluated.


“The results are not black nor white. GUV-induced smog is not so small that we can completely ignore it. But is is also not so bad that we should stop using GUV lights, especially in high risk environments. It is a case that calls for a risk/benefit analysis for different types of situations.”
