The A/C Duct carbon matrix is a grid composed of a proprietary mixture of carbon infused with titanium dioxide.
Odor-causing and potentilly toxic Voatile Organic Compounds (VOCs) can accumulate in interior spaces. If unchecked these airborne chemicals can build up to a dangerous levels.
As VOC molecules pass through the A/C Duct carbon matrix they are captured and held. Light from the UV lamp shines on the carbon/titanium dioxide surface creating a photocatalytic reaction which breaks down VOCs into simplier components.
After being transformed by the photocatalytic process all that remains of the once harmful VOCs is a simple water-vapor and carbon dioxide which pass back into the air leaving the carbon matrix clean and regenerated. Because of this, the A/C Duct UV system is virtually maintenance free.
