In an air conditioner, an air cleaner includes a charging unit for charging particles in the air and a dust collecting unit for collecting the particles charged by the charging unit by an electrostatic force. A filter cleaning device includes a device body to house a filter for capturing dust in the air in a movable form, and a part of the device body forms a supporting part to support the air cleaner. An indoor unit body houses the filter cleaning device, and houses the air cleaner by supporting it by the supporting part.

Precipitator unit of a two-stage electro filter where air to be cleaned from electrically charged particles is intended to flow through the unit. Said unit comprising at least two cylindrical precipitators (10, 11) that each comprise at least two electrode elements arranged at a gap distance from each other. Each one of the precipitators (10, 11) is also intended to be connected to a high voltage source. The respective electrode elements of a precipitator (10, 11) are connected to different poles of the high voltage source. The main planes of the precipitators (10, 11) are axially spaced in the air flow direction and a cone shaped duct (21) extends between the circumference of the first precipitator (10) and a center opening (13) of the second precipitator (11). A first amount of polluted air flows across the area of the first precipitator (10) and continues afterwards through the inside of the cone shaped duct (21) and out of the unit through the center opening (13) of the second precipitator (11). A second amount of polluted air flows outside the circumference of both the first precipitator (10) and the cone shaped duct (21) in order to be cleaned by the second precipitator (11).

A filter assembly having two frames. The two frames are connected by a hinge about which they rotate. The two frames hold a filter media there between. The two frames are locked using one or more latches that are located along a side rail of the at least one of the two frames. The one or more latches are flushed with an edge of the side rails of the two frames, to couple the two frames in a closed position.
