Abstract
An active air cleaning controller is connected to a forced air heating, ventilation and air conditioning (HVAC) system. The active air cleaning controller uses call signals from a thermostat to the HVAC system and/or sensor signals to determine when, and for how long, the blower of the HVAC system has been active and whether to independently activate the blower. The active air cleaning controller uses at least the collected information regarding the blower run time to determine when to activate the blower, in addition to its use within the HVAC system, to cycle and thus clean the air in a living environment independently of call signals used to activate heating and/or cooling functions of the HVAC system.
