> An aside: ventilation plus filtration is the major reason that the risk of Covid infections on flights was and is so relatively low: air in the cabin is replaced every couple minutes, fresh air is drawn from outside the plane, and mixed with recycled air passed through HEPA filters.
IME, the most effective thing to do in a house is filtration inline with the intake of a ventilation system.
In my case, I have an activated carbon and a MERV13 filter that cleans incoming outdoor air just before it's fed to the heat recovery and distribution system.
You still need a separate recirculating filtration system to deal with particulates generated within a house.
