ABSTRACT:
Behind a front panel of an air purifier are formed guide paths on the right and left sides thereof. A space between the front panel and a filter unit is partitioned by a partition plate into a front panel rear space and a filter unit front space. Part of an airflow that has entered the guide path through an air intake enters the filter unit front space, and the other part thereof enters the front panel rear space. When entering the front panel rear space, the airflow takes a sharp turn at a sharp turn corner. As a result, coarse dust is separated from the airflow, and the separated coarse dust falls into a dust box.
