    All HVAC systems recirculate the inside air, without bringing in fresh air.

    You’re wrong on that one. Ducted air conditioning systems do bring fresh air in, as well as positive inflow and heat recovery ventilation systems.

      Not all of them do. It’s mostly industrial units designed to bring in air to create a slightly positive indoor air pressure.
