Most UVGI methods can greatly reduce the spread of the virus, eliminating over 95% of the virus in some cases. The best way to apply UVGI to a recirculating airstream is to install it right past the return filter and before the heating and cooling coils. Having the UVGI installed in a way that it is positioned to see up to the cooling coils and drain pan is also beneficial as it can provide additional sanitization that way.
