Air Scrubber Plus is a device which is engineered to improve the indoor air quality of an occupied space. ActivTek Environmental is the company that manufactures the system. The Air Scrubber Plus device is designed to be installed into an existing HVAC system and intended for use as a fully integrated whole home air purification system.
How does the Air Scrubber Plus Work?
The Air Scrubber Plus device uses the circulated air generated by a home’s HVAC system and passes it through a cell (which they call ActivePure) which produces molecules to kill pathogens in the air and on surfaces.
According to ActivTek Environmental, the technology the Air Scrubber Plus device employs was initially developed in cooperation with NASA. Since space missions require astronauts to harvest their own food, technology is required to help them grow fruits and vegetables. To prevent plants from aging prematurely, a device needed to be created to control ethylene gas. Ethylene gas is naturally emitted from plants during the ripening process. In an enclosed space, ethylene can induce decay. To preserve the harvest, an ethylene reduction device was created and utilized by pulling air through titanium dioxide coated tubes which surrounded a UV light. When the gaseous air passed through this system, it was converted into trace amounts of water and carbon dioxide. An additional discovery was made when this technology development was found to kill pathogens.
