PROBLEM TO BE SOLVED: To provide a vehicular air-conditioning system that can maximize the opening area of an outside air inlet without too small an intake air quantity from an inside air inlet. SOLUTION: The number of filter members 7 through which cabin outside air taken in from an outside air inlet 4 passes is larger than the number of filter members 7 through which cabin inside air taken in from an inside air inlet 3 passes. The filter members 7 through which the cabin inside air passes can be thus thinned while ensuring a dust collecting capacity for the cabin outside air, so that the pressure loss of the cabin inside air by the filter members 7 can be reduced. Even when the opening area of the outside air inlet 4 is increased and the opening area of the inside air inlet 3 is spatially reduced accordingly, the disadvantage can be precluded that the intake air quantity from the inside air inlet 3 becomes too small.
