That's a difficult thing to test directly, so I think most people reason it out. In this case, you think about the virus, its interaction with air particles, and the interaction with a typical AC system with and without (unheated) filtration. I think the issue with ordinary filtration is that the virus is very small and can pass through most filters; by heating it the virus only needs to collide with the hot filter once, or (I think) get knocked around by fast air molecules to become unviable (is "killed" the right term for a virus that may not be "alive"?) Long story short, I think this invention looks great and I for one would use one, especially in cold climates where I already want to heat up the air.
