Air pollution can be controlled by following methods :

1) Electrostatic  precipitator - They are very efficient devices which removes 99% of particulates present in industrial and thermal power plant exhausts.

 2)Catalytic Converters - They are fitted in auto mobiles for reducing emission of gases. vehicles equipped with this should use unleaded petrol because lead in the petrol inactivate the catalyst.

3) Scrubber - It is used for removing gases like sulphur dioxide. in a scrubbr the exhaused is passed through spray of water and lime.
