摘要

PURPOSE: An air purifying filter is provided to efficiently collect fine dust although the flow of air passes through the film unit of the air purifying filter.;CONSTITUTION: An air purifying filter(100) includes a charged film unit(110) and a plurality of wedge-shaped protrusions(120). The film unit includes a plurality of through parts(111). The wedge-shaped protrusions are protruded along the circumference of the through parts. The lateral side of the film unit is folded into a zigzag shape. One side of the film unit includes an anodic side(113), and another side of the film unit includes a cathodic side(115). Anodic sides and cathodic sides are repeatedly faced by folding the film unit.;COPYRIGHT KIPO 2012
