Clean air is a necessity for good health but these days it is more of a luxury. The concern over increasing atmospheric pollution has led governments of all countries to pass strict pollution control laws. Installing air pollution control equipment in industries and power plants is now mandatory and any failure to do so attracts heavy penalties. The need for clean air has created a huge demand for air purifiers for home and office use.

Harmful chemicals and smoke particles are removed from industrial effluents using large scale air pollution control equipment and industrial ventilation systems. Polluted air is a health hazard, it decreases worker productivity. Electro Static Precipitators (ESPs) are large machines used for removing solid particulates from air. High voltage electro static fields are used to remove solid particulates present in smoke and other effluent gases.

Smoke and hot gases are passed through electrically charged plates, the solid particles get charged and stick to oppositely charged plates and are removed from the exhaust. Chemical scrubbers are employed for removing harmful gases and chemicals. They chemically remove harmful substances from the air before being released into the atmosphere.

Modern vehicles are also equipped with Air pollution control equipments. A device called a catalytic converter is used to scrub harmful fumes and hydrocarbons. The catalytic converter is basically a reaction chamber that oxidizes unburnt hydrocarbons, carbon monoxide, nitrous oxide etc. Similar technologies are also used in large scale industrial ventilation systems.

A home air purifier is a must if you are allergic to dust and pollen or if you live in a polluted area. Carefully consider your requirement before purchasing an air purifier. The commercial models are great at removing dust, smoke and biological matter from air. They employ a simple two stage filtration process.

Their filtration efficiency is about 99.97%, high speed fans are used to suck air through the filters. Commercial grade filters can remove germs, smoke particles, pollens, dust etc. Some costlier models even include ultraviolet light sources to kill germs. For best results use all forms ofair pollution control equipment in closed areas.
