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 (7) is mounted on a front surface of an ionization and dust collection unit (6) so as to be detachable. The pre-filter (7) is slidably guided by guide furrings (23) in a sub-frame (12), and is mounted on a front surface of the sub-frame (12). When the pre-filter (7) is mounted, ionization lines (15) are not exposed, so that the pre-filter (7) protects the ionization lines (15). When the ionization and dust collection unit (6) is detached from the main body housing, therefore, there is no problem that the ionization lines (15) might be cut by being accidentally touched with worker's hands, for example.

A method for forming a joint between a tube and a sheet includes forming an anvil at least within the tube, and welding the tube to the sheet in the presence of the anvil. The anvil includes an anchor which is placed within the tube near or at the joint to be formed. At least one washer is placed over the end of the anchor that is near the joint to be formed. A threaded fastener is then placed into the anchor to securely hold the anchor within the tube and to provide a backing substantial enough so that a friction stir weld can be formed. The threaded fastener and the washer can be used as a guide for the friction stir weld. Once the weld is completed, the anvil can be removed. The weld can be further processed to remove burrs and other material.
