APCO - Advanced Photocatalytic Oxidation In-Duct Air Purifier
Current PCO technology is limited by only being capable of breaking down simple indoor air contaminates such as odors in the air as they pass by the PCO cell. Traditional PCO cells are ineffective on more complex VOCs such as formaldehyde or toluene.
CAUTION: You must not look at a UV-C light bulb without eye protection, just like looking at the sun they will "burn" a spot in your retina.
