Abstract (en)

[origin: WO2022037973A2] An air purification unit having at least one electric filter module (2, 102) through which air to be purified can flow, which electric filter module has at least one first electrode (22, 122) and at least one second electrode (24, 124) between which the air to be purified flows and between which, by application of an high electrical voltage provided by a power supply module (7, 107), a first electrical field can be generated, wherein the at least one first electrode (22, 122) and the at least one second electrode (24, 124) form an ioniser (20) and wherein a mechanical filter module (3, 103) having at least one mechanical filter element (30, 103') is arranged downstream of the electric filter module (2, 102) in the flow direction (V) of the air to be purified, is characterised in that at least one third electrode (26, 126) is provided in the mechanical filter element (30, 103') or in the mechanical filter module (3, 103) behind the mechanical filter element (30, 103'), wherein a second electrical field can be generated between the at least one second electrode (24, 124) and the at least one third electrode (26, 126) by application of an electrical voltage.
