An air purifier is an electronic appliance that is used in homes and workplaces to improve overall indoor air quality. There are several different air purification technologies in the market, but the most common way an air purifier works is to draw air from a given space, such as a living room, into the unit and then have it pass through several layers of filtering devices within the unit and then have it recycled and released back into the room, through a vent from the unit, as clean or purified air.
