A computer box filter cover including a frame assembly that selectively attaches to a computer box and a door assembly that attaches to the frame assembly and that selectively closes over the entire front surface of the computer box. The frame assembly includes an extending lip which properly aligns the lower section of the frame assembly on the computer box so that the edges of the door assembly may be pressed against the edges of the frame assembly during use to form a seal around the front surface. The extending lip also allows the position of the frame assembly on the computer box to be adjusted so that the filter cover may be on different front surfaces. Located inside the door assembly is a filter and formed on the outside surface cover assembly opposite the filter is a plurality of air inlet openings through which air is drawn when the door assembly is closed over the front surface of the computer box. During assembly, the frame assembly is aligned and attached to the computer box in a position parallel and adjacent to the front surface. In a second embodiment, the lengths of the frame assembly and door assembly may be adjusted so that the filter cover may be used on different heights of computer boxes.
