Catalytic air filters typically use materials like platinum, palladium, or other catalytic metals. These catalysts are often coated onto substrates like ceramic or metal supports. When polluted air passes through the filter, the catalysts facilitate reactions that break down pollutants such as volatile organic compounds (VOCs), nitrogen oxides (NOx), and carbon monoxide (CO) into less harmful substances like carbon dioxide (CO2) and water (H2O).
