ABSTRACT OF THE INVENTION A fluid filter is formed by manufacturing a air laid batt containing randomly disposed structural fibers and a thermoplastic binder fiber. The interstices between the fibers are fixed by applying a latex resin to the batt, thereby fixing the pore sizes of the filtering media before the filtering media is molded. The filtering media is then molded into shape by using a plunger to tuck the media into an open cavity mold. The mold may be heated and pressure may be applied to the batt to mold the batt.
