Abstract
Abstract A climate-control arrangement ionizes the air in an enclosed space, such as the interior of a room in a building or the interior of the passenger compartment of a vehicle, by establishing in such space a steady or constant electric field. The arrangement includes one or more electrodes connected to a voltage source. In particular there is provided an electrode arrangement comprised of a base structure and a plurality of individually removable cover sheets covering the base structure and preventing the build-up of dust on the base structure. In this way, when dust has built up on the exposed one of the cover sheets, such sheet can be removed to expose the next and still clean one of the plurality of cover sheets.
