  • Publication number: 20120000169
    Abstract: A novel dust-filtering apparatus for a computer is disclosed. In one embodiment of the invention, the dust-filtering apparatus causes an inflow of air into a filtering chamber by using an air fan which is operatively connected to a DC power source. The inflow of air into the filtering chamber is cleaned and filtered by a first side of a filtering medium which is located on one side of the filtering chamber. A second side of the filtering medium faces a cleaned air evacuation chamber, which has at least an opening to allow the cleaned air to evacuate outwardly from the dust-filtering apparatus. In one embodiment of the invention, the dust-filtering apparatus is designed to be inserted into a drive expansion bay of a desktop computer, with a door on a front side of the dust-filtering apparatus for easy removal of the filtering medium.
