a pollution sensor for sensing a surrounding air pollution state by a gas sensor; a high voltage circuit for changing alternating current input power to direct current to apply the direct current to a first side of a flyback transformer and for selecting a second side organic voltage of the flyback transformer to output the voltage to a pollution collector; a motor driver for selectively rotating a fan motor; a relay driver for selecting a resistance value of the high voltage circuit and a rotation velocity of the motor driver in accordance with driving of each relay; and a microcomputer for comparing the air pollution state from the pollution sensor with a standard value and for selectively driving the each relay of the relay driver to automatically adjust pollution collecting performance and an amount of wind.
