Filter and manufacturing method thereof

Abstract

A filter manufacturing method includes: folding a filter media up and down and forming a wrinkle shape composed of a plurality of bent parts and a connection part connecting adjacent bent parts among the plurality of bent parts; and forming a conductive coating layer pattern on the filter media. The filter manufacturing method further includes: electrically connecting a first end and a second end of the conductive coating layer pattern to a first power source. In particular, the conductive coating layer pattern includes a plurality of parallel patterns, and the plurality of parallel patterns are formed to be positioned on the connection part.
