Developed over 25 years by research scientists, PECO is an innovative technology that uses free radicals—the same radicals used to destroy cancer cells—to break down pollutants at a molecular level, including viruses, bacteria, mold, allergens, and chemicals. Our PECO technology also meets all applicable criteria outlined by FDA guidance for air purifiers that may help reduce the risk of exposure to SARS-CoV-2 (COVID-19).
