摘要： A dust collection device for a sanding tool comprising a bag having a sidewall and a coupler attached to the bag. The sidewall comprising a first filter layer, a second filter layer, and an outer support layer. The first filter layer comprising a plurality of fibrillated electrostatically charged electret fibers forming a nonwoven web; the first filter layer having a total pressure drop between about 0.1 to about 4.0 mm H2O, and the first filter layer having a total basis weight between about 50 to about 450 gram/m2. The second filter layer comprising a melt blown microfiber nonwoven web; the second filter layer having a total pressure drop between about between about 5.5 to about 20.0 mm H20, and the second filter layer having a total basis weight between about 15 to about 75 grams/m2.
