Photo Catalytic Oxidation incorporates the usage of photons, packets of energy that make up light or light energy, combined with a photocatalyst, titanium dioxide, to eliminate airborne contaminates such as bacteria, viruses, mold, spores, fungi, allergens and gases.

Simultaneously, Volatile Organic Compounds, including solvents, alcohols, dyes and fuel oils are broken down into basic elements, water and carbon dioxide. The titanium dioxide photocatalyst becomes highly reactive when exposed to precisely controlled wave lengths of ultraviolet light (medical grade UVC). When organic pollutants become present, the photocatalyst attacks the chemical bonds of the bioaerosol pollutants, therefore converting the toxic compounds into benign constituents.
