Abstract:
1. An air cleaner for removing dust from ambient room air, comprising: a) at least one ion source; b) an elongated, generally cylindrical collector electrode support of non-conductive material supported by a base and having: c) a collector electrode having a chargeable dust-collecting surface formed on at least a portion of said one or more inside surfaces of said elongated, generally cylindrical collector electrode support of non-conductive material, said dust-collecting surface being a surface from which dust may be readily removed by manual cleaning while the elongated, generally cylindrical collector electrode support of non-conductive material is supported by said base; and d) a high voltage power supply capable of providing an ionizing potential for connection between said ion source and said dust-collecting surface; wherein said dust-collecting surface, acting as a counter-electrode, is positioned to induce the release of ions from said ion source and cause an ionic wind generated by said ion source and entraining dust to pass as an air flow through said inner volume of said elongated, generally cylindrical collector electrode support of non-conductive material and over said dust-collecting surface for collection by said dust-collecting surface of dust from the air that has been charged by ions emitted by said ion source; and wherein the dust collecting surface is exposed for manual access to allow manual cleaning and removal of dust collected on the dust-collecting surface while the elongated, generally cylindrical collector electrode support of non-conductive material is supported by said base.
