Saving energy through air filtration

Indoor air quality (IAQ) technologies combining ultraviolet germicidal irradiation (UVGI) and gas-phase purification allow engineers and facility managers to reduce energy consumption while ensuring a safe environment for building occupants. Now, the latest approach is to combine these systems with photocatalytic oxidation (PCO)—a chemical reaction caused by shining UV light onto a reactive medium, usually titanium dioxide.
