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. 

Add extra filtration to contain 87% of particles at 0.5 microns, including water and slurry up to a total of 30 pounds. Throw out hazardous dust properly sealed by the cap, which works as a solid first layer of containment.
