A room, its occupants and its HVAC is a steady state system, with people emitting virus particles and the HVAC system removing it. The goal is to have the HVAC system remove virus particles quickly enough so that the average particle density is low. You don't need the air coming out of the vent to be completely aseptic; you just need to remove a significant amount of the virus on each pass. |
