A dust collection unit for an electric precipitator and the electric precipitator including same, comprising: a plurality of dust collection films arranged apart from each other and including different, alternately arranged electrodes; a fixing member which is coupled to the plurality of dust collection films at one side or both sides where the plurality of collection films are arranged, so as to fix the plurality of dust collection films to be spaced apart from each other at specific intervals, and a ground electrode accommodated inside the fixing member. Accordingly, the dust collection performance of the electric precipitator may be improved by facilitating the discharge of a charging unit by suppressing an electric field generated by applying a high voltage to the plurality of dust collection films.

An electrostatic precipitator may have a set of collector electrodes and a set of repelling electrodes. The conductive portions of the collector electrodes and/or the repelling may be arranged in segments. The segments may have differing electrical properties or may be electrically isolated to facilitate differing potentials along an airflow path. The differing potentials results in differing electric field strengths along the airflow path.
