Dustless 8-10 Gal Wunderbag Micro Pre-Filter - 2 Pack

Turn your generic shop vacuum into a dustless one! Wunderbag Micro Pre-Filters are designed with a universal opening that fits most brands of 8-10 gallon shop-type vacuums, as well as a flexible gasket which easily accepts vacuum ports ranging from 2 to 2 3/4 inches in diameter.
