A depth filter design is disclosed which has little if any open void area upstream of the media. Preferably, it also has little if any open void area downstream of the media as well. A preferred embodiment uses layers of stacked, fibrous media with several of the layers being separated from the others by spacers which serve to compress the media and to prevent the bypass of fluid around the media adjacent the inner wall of the housing. Several designs for attaching the end caps which allow for the compression of the media are also disclosed.
