so for this to work, all the air in a room must be heated to 250C for a short time while it passes through the filter. How much energy does that use?

  No, the filter gets heated to 250 °C to destroy trapped viral particles. The air itself won't get heated up much, its contact time with the filter is too short.

    You'll have to heat up the air, or at least all particles in it, to at least 65 degrees to deactivate the virus.

      The viruses get trapped in the filter and burned up there by the 250 °C, so no need to heat up the air to 65°C.
