a support column positioned within the filtering volume of the cylindrical filter media.
2 . The water filter assembly of claim 1 , wherein the support column comprises a cylindrical support column, the cylindrical support column defining an outer diameter along the radial direction, the outer diameter of the cylindrical support column being about equal to the inner diameter of the cylindrical filter media.
3 . The water filter assembly of claim 1 , wherein the support column defines a plurality of openings for permitting liquids to flow through the cylindrical filter media and the support column into the filtering volume of the cylindrical filter media.
4 . The water filter assembly of claim 1 , wherein at least one cap of the pair of caps defines an outlet therethrough.
5 . The water filter assembly of claim 4 , wherein the outlet of the at least one cap has a diameter along the radial direction, the diameter of the outlet being about one inch.
6 . The water filter assembly of claim 1 , wherein the cylindrical filter media has a height along the axial direction, the height of the cylindrical filter media being about nine and seven-eighths inches.
7 . The water filter assembly of claim 1 , wherein each pleat of the plurality of pleats has a bend diameter, the bend diameter being about forty-five thousands of an inch.
8 . The water filter assembly of claim 1 , wherein the plurality of pleats comprises at least one hundred pleats.
9 . The water filter assembly of claim 1 , wherein the cylindrical filter media comprises cellulose, polypropylene, or polystyrene.
10 . The water filter assembly of claim 1 , wherein the cylindrical filter media defines a plurality of pores therethrough, each pore of the plurality of pores having a size between about one-half micron and two hundred microns.
11 . A water filter assembly that defines an axial direction, a radial direction, and a circumferential direction, the water filter assembly comprising:
a cylindrical filter media having a plurality of pleats spaced apart from one another along the circumferential direction, the cylindrical filter media defining an inner diameter and an outer diameter along the radial direction, the cylindrical filter media also defining a filtering volume within the cylindrical filter media;
a pair of caps mounted to the cylindrical filter media, the caps positioned at opposite axial ends of the cylindrical filter media, at least one cap of the pair of caps defining an outlet therethrough, the outlet of the at least one cap has a diameter along the radial direction, the diameter of the outlet being less than the inner diameter of the cylindrical filter media; and
a support column positioned within the filtering volume of the cylindrical filter media.
12 . The water filter assembly of claim 10 , wherein the support column comprises a cylindrical support column, the cylindrical support column defining an outer diameter along the radial direction, the outer diameter of the cylindrical support column being about equal to the inner diameter of the cylindrical filter media.
13 . The water filter assembly of claim 10 , wherein the support column defines a plurality of openings for permitting liquids to flow through the cylindrical filter media and the support column into the filtering volume of the cylindrical filter media.
14 . The water filter assembly of claim 10 , wherein the diameter of the outlet is about one inch.
15 . The water filter assembly of claim 10 , wherein the inner diameter of the cylindrical filter media is about two and one-eighth inches and the outer diameter of the cylindrical filter media is about four and one-half inches.
