Quartzel®, a photocatalytic substrate, can be used in air purification systems, including standalone air purifiers, in-duct HVAC residential units and large building systems. Using a process known as photocatalysis, the substrate destroys aldehyde, ethylene, phenolic compounds, alcohol compounds, alcene, alcyne, carbon family compounds, and sulfur. Photocatalysis uses a UV light and TiO2 semiconductor on the substrate to create a hydroxyl radical from the water present in the air. The hydroxyl is said to have twice the power of chlorine in destroying organic molecules and converts the organic molecules into basic molecules such as CO2 and H2O. Saint-Gobain Quartz
