ABSTRACT:
An abrasive article with an integral dust collection system. The abrasive article comprises a porous abrasive layer with openings, a first filter media with channels, a second filter media, a third filter media with channels, a fourth filter media, and an optional attachment layer. The openings of the porous abrasive layer cooperate with the channels to allow the flow of particles from the abrasive surface to the filter media.
