A conical folded-paper cartridge filter that is formed with one closed end and that has an end cap at the open end. The filter medium of the cartridge is pleated so that the open end can be collapsed to fit into the end cap, while retaining a central open space. The end cap may have a tube that protrudes inwardly into the central open space of the cartridge. The tube may support the structure of the cartridge. The tube also may assure that water flows from inside to outside of the pleated paper. Alternatively, the tube may assure that water flows from outside to inside of the pleated paper.
A process for making a water filter having the steps of hydropulping particulate and fibrous ingredients including a quantity of fibrillated cellulose with water to create a suspension, circulating the suspension in a molding tank, submerging a mold having cavities in the circulating suspension, applying a vacuum to the cavities to draw the suspension into the cavities such that the water passes through the mold and the ingredients accumulate within the cavities to form a dewatered material, ejecting the dewatered material from the mold to create a molded object, drying and curing the molded object and capping an open end of the molded object to make a filter that flows under gravity and is naturally hydrophilic with a mean flow path (MFP) as determined by porometry of less than 5 micron and preferably less than 2 micron.

COMPOSITION AND METHOD FOR MAKING A WATER FILTER BY ACCRETION
A process for making a water filter having the steps of hydropulping particulate and fibrous ingredients including a quantity of fibrillated cellulose with water to create a suspension, circulating the suspension in a molding tank, submerging a mold having cavities in the circulating suspension, applying a vacuum to the cavities to draw the suspension into the cavities such that the water passes through the mold and the ingredients accumulate within the cavities to form a dewatered material, ejecting the dewatered material from the mold to create a molded object, drying and curing the molded object and capping an open end of the molded object to make a filter that flows under gravity and is naturally hydrophilic with a mean flow path (MFP) as determined by porometry of less than 5 micron and preferably less than 2 micron.
