It isn't very practical, as long as you don't worry about getting the virus from the outside in, which would be an unusual thing to worry about for home owners.

Just vent it out in the open air and not on people.

Terrible for energy efficiency

That's what an ERV or HRV is for: https://en.wikipedia.org/wiki/Energy_recovery_ventilation https://en.wikipedia.org/wiki/Heat_recovery_ventilation

Et voilà, now it's no longer terrible for efficiency since you're recovering 70-90% of the energy. For fixed-plate exchangers there's no cross-contamination, either.
