Claim:
1. An apparatus for reducing air pollution, comprising: a piping system adapted for communication with an exhaust system; at least one compressor fan coupled to the piping system to draw exhaust from the exhaust system through the piping system; a cooling and saturating system to cool and saturate the exhaust with an exhaust cleansing fluid to break down one or more contaminants in the exhaust; a tank in communication with the piping system, the tank having at least one multi-layer filter assembly, the multi-layer filter assembly being adapted to allow the exhaust with the exhaust cleansing fluid to pass through and filter at least a portion of the one or more contaminants in the exhaust or the exhaust cleansing fluid, the at least one multi-layer filter assembly being disposed at an elevated position within the tank, wherein the exhaust is drawn from the exhaust system through the piping system and the cooling system by the at least one compressor fan into the tank and through the at least one multi-layer filter assembly to clean the exhaust or the exhaust cleansing fluid of at least a portion of the one or more contaminants, the elevated position of the multi-layer filter assembly facilitating additional passage of the exhaust through the multi-layer filter assembly to further clean the exhaust of at least a portion of remaining contaminants when present; wherein the multi-layer filter assembly includes at least one first filter, at least one second filter, and at least one intermediary member positioned between a corresponding at least one first filter and a corresponding at least one second filter; and a selectively accessible opening in the piping system, the opening permitting selective access for maintenance; wherein the cooling system is disposed along the piping system between the exhaust system and the tank.
