A method of forming filtration media, and the media so formed. The media has glass fibers of at least two substantially different diameters, such as 18 microns and 21 microns. Each of the glass fibers is continuous throughout the media and is substantially the same diameter along its entire length. The fibers can be made using a bushing plate in the Modigliani process in which the plate has orifices of at least two different sizes. The fibers made thereby have two different sizes, thereby resulting in a filtration media superior to conventional media, despite having a similar amount of glass and no more weight. The filtration media also has microspheres, in the range of about 3 to about 40 microns, which increase holding capacity.
