A multiple stage separation vortex flow air filter includes an air filter housing (AFH) having a central axis; a cylindrical helical plate located within the AFH proximate an upper shell bottom of the AFH; an air inlet eccentrically connected to the AFH to cause air flowing through the air inlet to create a vortex around the cylindrical helical plate; an perforated conical element in which the air flows through, the perforated conical element within the cylindrical helical plate around the central axis; an oblong conical casing that forms a conical passage and located along the central axis and partially within the perforated conical element, wherein air enters the conical passage through a whirling ring; and an air filter element within the oblong conical casing, wherein air flows through the air filter element and enters into an engine through an outlet pipe.
