Document Type and Number:
WIPO Patent Application WO/2011/142580
Kind Code:
A2
Abstract:
The present invention relates to a cylindrical air-cleaning filter holding static electricity, and an air-cleaning filter is disclosed in which a uniform pressure is achieved inside the filter and which thus suffers little pressure loss and has improved dust-collecting efficiency under all conditions of use, wherein: a polymeric synthetic resin film is electrically charged so as to form a filter element; a plurality of projections are formed on the filter element, with non uniform positioning; and then the film is wound into a cylindrical shape so as to form an air passageway that is parallel to the direction of flow of air, and form a uniform-pressure hole passing through the filter element between the projections of the filter element.
