Abstract
An air conditioner includes: a filter assembly including a first filter and a second filter sequentially disposed in an air flow path; a differential pressure sensor configured to detect a differential pressure value corresponding to a pressure difference between a front surface and a rear surface of the second filter; a memory; and a processor configured to store, in the memory, differential pressure values detected by the differential pressure sensor, wherein the processor may be further configured to: identify a degree of contamination of the second filter based on a magnitude of the differential pressure values, determine a rate of change of the differential pressure values stored in the memory over time, and identify a degree of contamination of the first filter based on the rate of change.
