What is PCO?
Photocatalytic Oxidation (PCO) technology utilizes ultraviolet (UV) light in conjunction with a titanium dioxide (TiO₂) catalyst to actively break down airborne pollutants. As ethylene gas and other contaminants pass through the PCO reaction chamber, the UV light activates the surface of the TiO₂, initiating an intense oxidation process. Through this reaction, harmful gases—such as ethylene—are broken down into harmless byproducts, primarily carbon dioxide (CO₂) and water (H₂O).
Further testing conducted by NASA has demonstrated that PCO technology extends far beyond the mere removal of ethylene. This technology effectively eliminates a diverse array of carbon-based airborne pollutants. These include foul odors, volatile organic compounds (VOCs), mold spores, fungi, bacteria, and viruses. Rather than allowing these pollutants to accumulate within the indoor environment, the oxidation process breaks them down at a molecular level.
One of the key distinctions between PCO and traditional air purification technologies lies in how pollutants are handled. Traditional filtration systems typically capture particles and contaminants within the filter medium, where they remain trapped. In contrast, PCO technology actively destroys pollutants rather than merely collecting them. This oxidation process is capable of neutralizing extremely minute contaminants—even those smaller than 0.1 microns—such as bacteria, viruses, fungi, and many volatile organic compound (VOC) molecules.
While advanced oxidation technologies primarily target gaseous and microbial contaminants, mechanical filtration plays a vital complementary role within air purification systems. High-Efficiency Particulate Air (HEPA) filters are widely employed to capture particulate matter, including dust, pollen, mold spores, bacteria, viruses, and common allergens. Activated carbon filters further enhance air purification by adsorbing smoke and chemical gases—including volatile organic compounds (VOCs) such as formaldehyde. By combining multiple technologies—such as HEPA particulate filtration, activated carbon chemical adsorption, and PCO oxidation for the molecular-level destruction of pollutants—modern air purification systems are able to provide comprehensive protection against a broad spectrum of indoor air contaminants.
