Abstract: Proposed is an air purifying filter. The air purifying filter includes a filtering layer (30) configured as a dielectric which collects minute particles, a first electrode layer (50) laminated on a side of the filtering layer (30) and comprising insulated wires (51) to which power is able to be applied, and a second electrode layer (70) laminated on a side of the filtering layer (30) opposite to the side of the first electrode layer and comprising a conductive material such that a polarity opposite to a polarity of the first electrode layer (50) is applied to the second electrode layer or the second electrode layer is grounded.

Abstract: Proposed are an air purification filter (1) and an air purifier (200) including the same. The air purification filter includes a filtering layer (30) configured as a dielectric which collects minute particles, a pair of electrode layers (50, 70) laminated on opposite sides of the filtering layer (30), respectively, and configured to receive power so as to generate polarization through an electric field in the filtering layer (30), and a connection module (100, 100′). The connection module (100, 100′) is coupled to at least any one of the opposite ends of the pair of electrode layers (50, 70) such that the coupled portion of the connection module is insulated from an outside thereof and is electrically connected with an external power supply part.
