New Device Traps Viruses, Airborne Pathogens (image) Washington University in St. Louis Share Print E-Mail Caption The new air cleaner uses a novel corono-soft X-ray system that enhances charging efficiency and captures particles at high efficiency. Difficult-to-charge particles are readily charged and trapped in the electrical field. Due to high ion concentrations and an oxidizing environment, organic species are readily converted to carbon dioxide. A nanostructured catalyst coating destroys the toxic particles.
