Abstract

An electrostatic precipitator includes a dust collecting sheet configured to emit ions and configured to collect an aerosol charged by the ions, a power supplier electrically connected to the dust collecting sheet, a plate-shaped structure arranged upstream of an air flow path rather than the dust collecting sheet, and including at least one of a filter mesh or a grille including a plurality of openings, a potential stabilizer arranged between the plate-shaped structure and a ground, and configured to stabilize a potential of the plate-shaped structure, and a controller configured to control the power supplier to supply power to the dust collecting sheet.
