| Sun or UVB augmented lighting | Vit D | Kill virus* |
| UVC air cleaner | - - - - | Kill virus* |
UVC from the sun does not reach the surface of the earth
UVB from the sun, etc, kills viruses, but not as well as UVC
* Killing virus ==> reduce infecting self & others

"In a study within three office buildings, UVGI systems were turned on and off multiple times while not informing occupants. Work related self-reported acute health symptoms were assessed using questionnaires. There were statistically significant 20% to 40% decreases in symptoms during periods of UVGI system operation." - UV-C reduces pediatric viral respiratory illness by 44% reporting on 2018 study
