An air purification system comprises a housing, a generally S-shaped duct mounted within the housing, at least one blower mounted within the housing for circulating air through the system, and purification structure for removing contaminants from the air. The system preferably comprises two blowers, a master control switch for activating one of the blowers to circulate air through the filter, and a secondary control switch for activating the other blower and the UVC source to initiate a UVC purification process to further purify the filtered air.

[ What is claimed is:] [1.] An air purification system comprising:a housing having an intake opening for permitting air to enter the housing and an outlet opening for permitting air to exit the housing;a curved hollow duct positioned at least partially inside the housing and having a passage extending between an inlet end in communication with the intake opening of the housing and an outlet end in communication with the outlet opening of the housing, the passage having a gradually decreasing cross sectional area between the inlet end and a narrow-most section positioned along the passage and a gradually increasing cross sectional area between the narrow section and the outlet end, the narrow-most section having opposite first and second sides, the passage curving at the narrow-most section so that said first side of the narrow-most section is concave;a blower in communication with the passage for drawing air through the housing intake opening and blowing air through the passage from the inlet end to the outlet end; andan ultraviolet energy source mounted in the narrow-most section parallel to said first side of the narrow-most section of the passage adjacent said second side so that substantially all of the air blown through the passage passes between the energy source and said first side of the narrow-most section in an arcuate path around said energy source.
