Abstract:
Provided is an air purifier that can increase the amount of air sucked in per unit time with minimal increase in size. An air purifier 1A comprises a housing 2 having an inlet and outlet, a blower 5L, 5R installed in the housing 2, and a filter 6. The blower 5L, 5R has a fan 52 that generates an airflow by rotating, and an intake portion 56L, 56R that is located upstream of the fan 52 in the airflow direction and where air is sucked. The rotation of the fan 52 draws air into a cavity 10U through the inlet, causes the air drawn into the cavity 10U to flow toward the outlet 22L, 22R, and blows the air out through the outlet 22L, 22R. The air flowing from the inlet toward the outlet 22L, 22R is passed through the filter 6. The intake portions 56L, 56R of the blowers 5L, 5R are arranged so as to face each other. The inlet is located between the blowers 5L, 5R in the direction in which the intake portions 56L, 56R face each other.
