A commercial Air Purifier is a device that employs the use of electric charges to get rid of impurities from the air. It works by applying energy to the particulate matter to be removed without tampering with the air flow. Originally, the purifiers were used for air pollution control by removing particulate matter from waste gases in industries. Today, they are used for indoor air pollution control.
Most of these purifiers consist of two compartments; a charging and collection sections. Application of high voltage to the ionizing wires creates a very strong electric field between the wires. Electrons within the impure air containing matter such as smoke particles, mould spores, fine dust and pollen are pushed at a very high velocity from the negatively-charged field to the positive end. As they move along, they come into collision with contaminants creating more electrons which sustain the system.
Finally, the ionized impurities are moved by the moving gases into the collectors which have a very strong electric field and henceforth the particles are trapped at the charged collector plates.
