Design of optical cavity for air sanification through ultraviolet germicidal irradiation

The transmission of airborne pathogens represents a major threat to worldwide public health. Ultraviolet light irradiation can contribute the sanification air reduce pathogen transmission. We have designed compact filter for inactivation by means UVC LED sources, whose effective irradiance is enhanced thanks high reflective surfaces. used ray-tracing and computational fluid dynamic simulations model device maximize performance inside volume. Simulations also show inhibition SARS-Cov-2 in case fluxes. This study demonstrates that current available technology purposes.
