Fiber webs including synthetic fibers

Abstract

Filter media suitable for various applications and related components, systems, and methods associated therewith are described. The filter media may include a fiber web having a mixture comprising non-fibrillated synthetic fibers and fibrillated fibers, such as lyocell. The fiber web may also include multi-component fibers (e.g., bi-component fibers). In some embodiments, glass fibers are not incorporated into the fiber web.

What is claimed is: 
     
         1 . A fiber web comprising a plurality of non-fibrillated synthetic fibers and a plurality of fibrillated fibers, wherein the fiber web comprises between about 30 weight % and about 95 weight % of the non-fibrillated synthetic fibers and has a dust holding capacity of greater than about 30 g/m 2 .
