Abstract
An air purifier includes a housing, a first blower, a second blower, and a filter. The housing has a cavity inside, an inlet and an outlet. The first blower has a first fan in the housing. The second blower has a second fan in the housing. The second blower faces the first blower in an opposing direction. The inlet is located between the first blower and the second blower in the opposing direction. The inlet opens in a direction intersecting the opposing direction. The first fan of the first blower and the second fan of the second blower generate airflow such that air flows into the cavity through the inlet, and flows from the cavity through the filter to the outlet.
