Abstract

The present invention is directed to a filter media comprised of an electro-conductive scrim so as to improve on the dissipation time of an electrostatic charge. Further, the present invention is directed to a method of making such a filter media, which is formed through hydroentanglement, thus avoiding the deleterious effects of mechanical needling, while providing a filter media having the requisite strength characteristics, without possessing a limiting factor in performance. The filtration media of the present invention also demonstrates a highly desirable uniformity for cost-effective use.
