The invention is an air filter for reducing the amount of particles in air. In the preferred form, the particles are odour particles. The air filter comprises two spaces disposed between an air inlet and an air outlet. Odorous air is drawn into the air filter and pre-treated in a first space, having air flow baffles and jets which both agitate and charge the air by a process of triboelectrification. In the second space the airstream impinges upon a number of spaced-apart baffles or structured layers. The odour particles in the air are attracted to the surfaces of the baffles and are removed by the action of the water flow. The air filter of the present invention can treat air from installations such as agricultural operations, air from apartment buildings, air from restaurants, factories and other industrial facilities, vehicle exhaust system and effluent ponds and is also applicable to removing other particles types such as pollen.
