PURPOSE: An air purifying filter is provided to reduce the loss of pressures and to improve the collecting efficiency of dust by being shaped into a plate form and maintaining the uniform pressure. CONSTITUTION: An air purifying filter includes a polymer synthetic resin film of a pre-set width. The polymer synthetic resin film is charged, and plate shaped filter elements(10) with a plurality of protrusions is stacked on the polymer synthetic resin film. An air path in parallel with the flowing direction of air is formed. Pressure balancing holes(13) connecting both sides of the filter elements are formed between the protrusions of the filter elements.
