Abstract

When an ionization section is taken out of a main body housing of a conventional air cleaner in order to wash the ionization section, an ionization line may be cut by being accidentally touched. In order to avoid this problem, a pre-filter ( ) is mounted on a front surface of an ionization and dust collection unit ( ) so as to be detachable. The pre-filter ( ) is slidably guided by guide furrings ( ) in a sub-frame ( ), and is mounted on a front surface of the sub-frame ( ). When the pre-filter ( ) is mounted, ionization lines ( ) are not exposed, so that the pre-filter ( ) protects the ionization lines ( ). When the ionization and dust collection unit ( ) is detached from the main body housing, therefore, there is no problem that the ionization lines ( ) might be cut by being accidentally touched with worker's hands, for example.
