Abstract
Abstract A computer dust filter cover comprises an open cell synthetic foam sheet formed into a bonnet-like arrangement by an elastic strap. The cover is readily attached and removed from the computer housing front or side panels to cover the disc slots while the computer is in use and without interfering with the use of the computer. The cover can remain in place when the computer is not in use to protect the interior of the housing and parts therein from contamination by particulates at all times.
