Disclosed herein is a plasma filtration insert assembly having in one example an outer casing comprising an air inlet an air 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 air gap there between, and wherein there is no fluid path between the air inlet and the air 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 in cross-section.
