An emission control device and method are provided for treating exhaust to reduce pollutants contained therein. The device includes a first chamber through which the exhaust passes. First and second metal grids are disposed within the first chamber at a predetermined distance from each other. Voltage is supplied to the insulated first grid by an electrical induction coil at a predetermined frequency depending upon the application. Electrical charges are generated between the first and second grids which electrically ionizes the exhaust stream. The exhaust stream is then further treated at a second chamber having strata. The strata can further include or exclude noble metals for treatment of the exhaust.
