PURPOSE: A ventilation apparatus using a motor driven pump is provided to maintain indoor air clean by using the motor driven pump. CONSTITUTION: A ventilation apparatus using a motor driven pump comprises a dust sensor. The motor driven pump sucks and discharges air. An existing ventilation apparatus performs low ventilation efficient by using a fan. The dust sensor detects foreign materials in the air. The motor driven pump is automatically operated in case much dust is in the air. The ventilation apparatus using a motor driven pump is operated through ON and OFF operation, a timer operation, a reservation operation, and a wireless operation through an infrared ray method and a radio method.
