Disclosed herein is an electric precipitator, which efficiently charges dust particles without lowering dust collecting efficiency, although a velocity of an air flow is not uniform, and an air cleaner having the same. The electric precipitator includes a charger unit including at least two corona charge cells to charge dust particles contained in air, and a collector unit to collect the dust particles charged by the corona charge cells. The at least two charge cells include a first cell, through which the dust particles pass at a first velocity, and a second cell, through which the dust particles pass at a second velocity different from the first velocity, and where the electric current in a charge cell is higher when the air flow velocity therein is higher. |
