Photocatalytic oxidation (PCO) technology was created by NASA for use on the international space station. PCO replicates and event in nature when sunlight contacts moisture in the atmosphere creating oxidizers which clean the air. PCO technology creates natural oxidizers that sanitize the air inactivating viruses, bacteria, molds and VOCs. PCO technology dramatically improves indoor air quality and effectively eliminates odors. Works by producing safe, chemical free oxidizers that attach themselves to pathogens puncture the cell walls of the organisms and remove the hydrogen from the pathogen. Hydrogen is essential for the life of the organism removing the hydrogen does not allow the pathogen to live or grow. This same method is effective for COVID-19 (Corona Virus).
