An apparatus for purifying and humidifying air which enables separate supply of purified air and humidified air and controls the amount of humidified air discharged and which includes dual flow paths to increase the efficiency of air transfer. The apparatus includes a case having a suction port through which external air is introduced thereinto and a discharge port through which the introduced air is discharged, a circulation fan for causing the introduced air to flow toward the discharge port, a filter unit disposed in the case to filter the introduced air, a humidification unit disposed at a low position in the case to supply the air passed through the filter unit with moisture, and a flow path control unit disposed between the suction port and the humidification unit to control flow of the air passed through the filter unit.
