Abstract
The fiber webs described herein may be incorporated into filter media and filter elements. The webs may exhibit a high permeability and stiffness, at a low thickness. The stiffness can be sufficient for the webs to be pleated to include sharp, well-defined peaks which can be maintained in a stable configuration during use.
