Abstract
A fluid filter material configured to have a desirable efficiency at a low pressure drop is presently disclosed. The fluid filter material has a relatively open pleatable scrim comprised of a wet-laid or dry-laid material with natural and synthetic fibers. A layer of expanded polytetrafluoroethylene filaments have a first surface bonded with the pleatable scrim and the fluid filter material is pleatable and self-supporting. The natural fibers in the scrim may comprise cellulosic fibers, cotton, rayon, or other natural fibrous materials. The scrim may also comprise synthetic fibers.
