An apparatus for cleaning air filters by a combination of vibration, air pressure, and suction. A support member includes a first inclined wall sloped more steeply than a second inclined wall, providing generally V-shaped supporting surfaces which cause the filter being cleaned to rotate as it is vibrated. The vibration of the filter also loosens trapped impurities therefrom, and this vibration is enhanced by resiliently suspending the support member from a housing. The loosened impurities fall down the slopes of the inclined walls and are removed by suction provided in a channel extending lengthwise along the bottom of the support member. An exhaust blower is connected to a port in the suction channel to apply suction to the filler and to remove loosened impurities. The exhaust blower is also connected to an inner suction tube, which applies suction to an inner periphery of the air filter. An air diverter directs the exhaust air flow through either the suction channel, the suction tube, or a combination of both. An air blowing tube is provided to blow pressurized air from spaced air nozzles through a selected inner or outer periphery of the air filter to loosen trapped impurities therefrom. The blowing tube reciprocates across the selected filter periphery to provide a thorough cleaning of the filter. The suction and blowing tubes preferably telescope vertically in sleeves to accommodate filters of differing diameters. The suction and blowing tubes may also be tiltably mounted to allow cleaning of filters of different shapes, such as conical filters.
