Abstract: An air cleaner has an electron generator that includes a pointed head, a collector element and an electric circuit included in the electron generator for generating a negative potential on the pointed head and a positive potential on the collector element. The pointed head is mounted at the free end of a cylinder of electrically non-conductive insulating material. The cylinder includes the electric circuit at the free end whereas its other end enters the collector element, which is cylindrical and is of electrically conductive material.

Abstract: An air cleaner comprising an electron generator (12-13) that includes a pointed head (12), a collector element (14) and an electric circuit (13) included in the electronic generator (12-13) for generating a negative potential on the pointed head (12) and a positive potential on the collector element (14). The pointed head (12) is mounted at the free end (111) of a cylinder (11) comprised of electrically non-conductive (insulating) material. The cylinder (11) includes the electric circuit (13) at one end whereas its remaining end (112) enters the collector element (14), which is cylindrical and comprised of electrically conductive material.
