Abstract: Disclosed is a blower unit of an air conditioner for a vehicle which is freely changed in design of an intake unit of a blower case, increases dust collection efficiency of an air filter, and improves continuity of filtration-to-area efficiency so as to increase an exchange cycle of the air filter. The blower unit includes a blower case having an inside air inlet for introducing inside air and an outside air inlet for introducing outside air, a blower wheel disposed inside the blower case and rotated by a blower motor, and an air filter disposed at the upstream side of the blower wheel in an air flow direction to filter impurities. The air filter includes: a main filter part corresponding to an air intake area; and auxiliary filter parts which are formed in the outside direction of the air intake area.
