An air purification system for use with an air conditioning apparatus which includes an air circulation system having supply air flow to a given area and return air flow for drawing air from that area. The air purification system includes an inlet and an outlet. A conduit communicates the inlet with the air circulation system for drawing therefrom a portion of the air passing therethrough. A conduit communicates the outlet with the air circulation system downstream of the inlet for returning the portion of the air back to the circulation system after it has passed through the air purification unit. A superheating conduit also communicates between the inlet and an exhaust of the air conditioning apparatus, such as the chimney of a furnace.
