Abstract: Disclosed herein is a plasma reactor insert assembly having in one example an outer casing comprising; a fluid inlet; a fluid outlet; an electric power input; and electric power connector; a transformer bracket coupled to the outer casing; at least one step-up transformer attached to the transformer bracket. The insert in electric communication with the electric power connector; a plurality of substantially parallel dielectric tubes in electric communication with the transformer; at least one grounded plate positioned between each dielectric tube with a fluid gap there between, and; wherein there is no fluid path between the fluid inlet and the fluid outlet except by passing between one of the dielectric tubes and one of the grounded plate. In one form, each grounded plate is v-shaped or arcuate v-shaped in cross-section. A method for disinfecting or sanitizing using the plasma reactor is also described.

Abstract: Disclosed herein are examples of open mesh style monolith filters utilizing an ozone-depleting catalyst. In addition, pairing of an ozone depletion coated filter with electrostatic filter is disclosed herein such that the electrostatic filter is provided upstream of the ozone depletion coated filter so as to reduce the volume of particulates encountered by the ozone depletion coated filter and thus extending the useful life of the ozone depletion coated filter. In addition, pairing of the treated filter as well as the combined treated filter and electrostatically charged filter with an air ionizer is disclosed herein so as to further reduce particulates in the air stream, reduce chemical contaminants in the air stream, and provide a low pressure airflow through the filter. A method for making an economical ozone depletion filter that is energy efficient (with open mesh monolith structure) with high air cleaning efficiency at ambient temperature.
