Air scrubbers are air cleaning devices that use a search and retrieve method to eliminate contaminants the air inside a house. As air flows through a ductwork system the air scrubber produces negative ions that attach to pollutants floating in the air that are too small to be captured by a normal air filter.
To create the negative ions the device uses small metal tubes that are arranged in the shape of a honeycomb. As air travels through these tubes it passes through ultraviolet light. This creates the negative ions that circulated through the house.
As the negative ions circulate they attract positively charged particles such as bacteria, pollen, and other allergens. When the negative ions and positive particles bond they create larger, heavier particles that fall to the ground or on surfaces where they are captured by an air filter.
