Abstract
A filter media and methods are provided. The media is stretchable and exhibits a high degree of elongation which thereby extends its surface area during pleating. By extending surface area of media during pleating, the initial differential pressure is lowered as the area of media is stretched while keeping the same efficiency range with a compressed thickness of media on the affected area.
