ABSTRACT:
A high efficiency air filtration media comprises: about 5 to about 20% by weight of fibrids; about 5 to about 20% by weight of a binder; and about 60 to about 90% by weight of staple fiber. The media has a pressure drop of air across a face of the media of less than or equal to 0.4 inches of water. The media, also, has a sodium chloride particulate test for respirator filter percent efficiency of greater than or equal to 60%.
