Abstract

Sterilisation of airflow in a duct may be achieved by irradiating the air with light in the ultraviolet spectrum. Electrodeless bulbs may be enclosed in part of a duct and fed with RF energy in order to energize the bulb. The RF energy may be contained using grids dimensioned to be opaque to the selected RF wavelength.
