The present invention relates to an air conditioner including a dust collecting filter assembly for collecting foreign substance from the air sucked in through an inlet. The dust collecting filter assembly includes a high-voltage electrode film, a ground electrode films alternately disposed to face the high-voltage electrode film, a separator film disposed between the high-voltage electrode film and the grounding electrode film so that the high-voltage electrode film and the grounding electrode film are spaced apart by a predetermined interval, and a fastening part to fasten the high-voltage electrode film, the ground electrode film, and the separator film together and integrate them. With this configuration, it is possible to simplify the manufacturing process of the dust collecting filter assembly provided in the air conditioner, minimize the distance between the high-voltage electrode film and the ground electrode film, and improve the dust collection performance by improving a dust collection area by the separator film.

An air-conditioning system is provided that may include a first air-processing apparatus, which includes a first outlet formed to be open toward a floor and a first inlet formed to be open in a direction inclined relative to a direction in which the first outlet is open and is configured to deliver heat-exchanged air to the first outlet, and a second air-processing apparatus, which includes a second outlet formed to be open in a direction parallel to the first outlet and a second inlet formed to be open in a direction parallel to the first inlet and is configured to deliver purified air to the second outlet. The first outlet and the second outlet extend in a lateral direction, and the first air-processing apparatus and the second air-processing apparatus are arranged in the lateral direction.

The present disclosure is directed methods and apparatus that improve the energy efficiency of an air filtration apparatus while maintaining a high level of filtration capabilities. Air filtration apparatus consistent with the present disclosure may include an input, a fan, a pre-filter, and electrical conductors that provide a high voltage used to charge particles in an air flow. This apparatus may also include a secondary filter that traps charged particles. The pre-filter may filter air using conventional means, where a high energy electric field generated by high voltage conductors may charge particles in the air such that those particles may clump together and be captured in the secondary filter. These clumping effects may allow a less dense filter media to capture particles that would otherwise pass through the less dense filter. Micro-organisms attached to the captured particles may be degraded or destroyed after they are captured in the secondary filter.
