ABSTRACT:
Filtration material comprising a web comprising meltblown fibers and staple, electrically charged fibers randomly dispersed among the meltblown fibers. The filtration material can be formed in planar configurations and in configurations other than planar. Non-planar configurations can extend the useful working area for a given filter element's cross-section without requiring an additional corrugating or pleating process step. The filtration material exhibits high strength and low pressure drop.
