A water spray-based air purification system having a humidification portion and a dehumidifying portion is operatively installed in an air handling unit used to recirculate air within a conditioned space. A blower within the air handling unit housing operates to draw return air into the housing, flow the air across the entire air purification system, and then discharge the purified and humidified air back into the conditioned space. A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system. Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water. The operation of the air handling unit and its associated air purification system are automatically monitored and regulated by a programmable air quality and monitoring and control system which is coupled to multi-parameter sensing apparatus that continually detects temperature, humidity and gaseous and particulate pollution levels present in the conditioned space or the air being delivered thereto from the air handling unit.
