Abstract
A reactor for non-thermal plasma assisted treatment of a gaseous medium incorporates at least one electrically conducting mesh filter element positioned so that gaseous medium passes therethrough. At least one dielectric barrier layer provides for a dielectric barrier type discharge, when an electrical power supply is connected to the electrodes to generate the plasma.
