ABSTRACT:
An air filter, an elevator having the same, and an air conditioning control method thereof purify the air inside the elevator to make the air safe and pleasant using a micro plasma ion generator (MPI). The elevator includes a cage which moves up and down in a vertical direction of a building and an air filter which purifies the air inside the cage. The air filter includes an ion generator which generates ions by a plasma discharge to discharge the ions into the cage, a dust sensor which detects a dust contamination level in the cage, and a controller which compares the dust contamination level detected by the dust sensor with a predetermined standard contamination level and operates the ion generator If the dust contamination level is equal to or greater than the predetermined standard contamination level.
