Disclosed is a filter which comprises the following: an air permeable polymer mesh including holes in the same size and uniform arrangement, obtained by weaving a monofilament formed of a polymer resin into a lattice form; a polymer web stacked on at least one surface between the upper and lower surfaces of the polymer mesh, and including uneven microholes formed by twisting polymer fibers in a spider web form; and a fluorine resin coating layer coating the entire surface after stacking the polymer mesh and the polymer web. The filter forms a one body by combining the polymer mesh and the polymer web through coating. |
