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.

Filter and manufacturing method thereof

A filter includes a dust collecting unit, and the dust collecting unit includes: a filter media formed in a wrinkle shape including a plurality of bent parts folded up and down in a direction parallel to a plurality of parallel patterns and a connection part; a conductive coating layer pattern including a plurality of parallel patterns; and a first power source electrically connected to a first end and a second end of the conductive coating layer pattern and configured to apply a voltage, wherein the connection part connects the adjacent bent parts, a parallel pattern of the plurality of parallel patterns is disposed in the connection part, and the plurality of parallel patterns includes a first and a second adjacent parallel patterns, and a first current flowing through the first adjacent parallel flows in a direction opposite to a second current flowing through the second adjacent parallel pattern.

A method of preparing a stable stick-type cosmetic composition includes separately stabilizing a clay mineral dispersion and a moisturizing component, thereby uniformly dispersing components in the composition. In a typical stick-type composition, components are not uniformly dispersed, and thus a stick formulation prepared using the same is easily broken upon external impact or the like, but the stick formulation prepared by the method of the present invention is maintained in spreadability and sensation of use, and is not easily broken.
