The outer cylindrical frame is coaxially arranged around the inner cylindrical frame. The circular disc is fastened to a first end of the inner cylindrical frame and the outer cylindrical frame. The bonding base is fastened to an opposite second end of the inner cylindrical frame and the outer cylindrical frame. A first opening of the bonding base communicates with a first hollow region between the inner cylindrical frame and the outer cylindrical frame. A second opening of the bonding base communicates with a second hollow region within the inner cylindrical frame. The air filter medium is filled into the first hollow region through the first opening. The fabric cover encloses the outer cylindrical frame, circular disc and bonding base to expose the second opening.
