I totally believe that UV light is great at killing pathogens and that UV belongs in ventilation systems, but we presumably need to know how much UV light is needed.
The UV doses needed also seem to depend on a lot on the type of pathogen. For example, viruses require a higher dose than bacteria. In
* what UV frequencies to use
* what intensity of light to use
* what volume of air can flow past it per second

it required up to 6 times as much UV to inactivate viruses compared to bacteria.
