A seal device that when inserted, impedes entrance of airborne contaminants drawn into a floppy disk drive while not in operation. Accomplished by having a body of sufficiently rigid sheet material to provide support and structure for a strip of seal material. Size of the body is configured to fit into a floppy disk drive and incorporates external stops to prevent the over insertion of the inwardly extending card portion to prevent damage to parts internal to the floppy disk drive. Thus the configuration of the body portion is such so as to not engage sensitive floppy drive internal mechanisms or require modification of the hardware of the floppy drive. The included seal strip is of sufficiently elastic solid or porous material capable of impeding airborne contaminants when bedded in a floppy disk drive port orifice with that strip being of sufficient size to encircle the card portion and to fill the mouth of the floppy disk drive.
