Abstract: An air conditioning apparatus is provided. The air conditioning apparatus includes: a filter configured to have a first conductor layer, an insulating layer having a thickness in the range of 5 nm to 1000 nm, and a second conductor layer which are sequentially stacked, and include a plurality of holes penetrating through the first conductor layer, the insulating layer, and the second conductor layer; a fan assembly configured to suck air from the outside and provide the sucked air to the filter; a power supply device configured to provide alternating current power between the first conductor layer and the second conductor layer; and a processor configured to control the power supply device to selectively vary a frequency or a voltage magnitude of the alternating current power provided to the filter.
