Abstract

The fiber webs described herein may be incorporated into filter media and filter elements. The fiber webs may exhibit a high dust holding capacity. The fiber webs may also exhibit a low thickness. The fiber webs may be sufficiently flexible and/or deformable so that they may be processed to include a series of waves (also known as flutes) that extend along the cross-machine direction.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fiber web having
 a dust holding capacity of greater than about 3 mg/cm 2 ;   a basis weight between 30 g/m 2  and about 100 g/m 2 ; and   a machine direction tensile elongation of greater than about 3%.
