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.
