>> That isn't going to do a thing about CO2 Seems like we're forgetting that the objective is not to reduce CO2, it's to reduce the pathogens in the air. Since it's difficult to measure pathogens directly, we use CO2 concentrations as a proxy, since high CO2 means poor ventilation which means potentially high pathogens.
