Abstract
A computer system includes a computer chassis housing a processor and having a dust filter disposed in an airflow pathway through the computer chassis. A plurality of electrodes is disposed across an area of the dust filter, and a voltage source is provided having a negative terminal and a positive terminal. A controller selectively couples a first subset of electrodes to the negative terminal and selectively couples a second subset of electrodes to the positive terminal, wherein a voltage differential between the first subset of electrodes and the second subset of electrodes is sufficient to cause electrostatic movement of dust from an area of the dust filter near the first subset of electrodes to an area of the dust filter near the second subset of electrodes.
