Isn’t my expensive air filter cleaning the air enough?

UV-C Lights kill viruses and super small bacteria that don’t get trapped by the thickest of furnace/AC filters. Even HEPA filters can’t catch them. Viruses are as small as 0.003 microns and bacteria down to 0.2 microns. HEPA filters, if you’re lucky, claim to catch 0.3 microns, but good luck getting any airflow. Thick filter = minimum air flow, great filtration. Thin filter = maximum air flow, little filtration. Optimum filter (MERV 9-11 rating) = good filtration and good air flow.
