Filter cartridge

A filter assembly for a container comprising:

• a fluid dispensing spigot having a portion located on the outside of said container;
• an extension member connected to or integral with said spigot, and extending through a wall of said container and into said container such that said spigot is in fluid communication with fluid within said container;
• and
• a filter housing assembly having a filter housing and a right-angled neck portion forming a right-angle with respect to said extension member at a first end and a cylindrical base portion at a second end, said right-angled neck portion having said first end coaxial with said extension member, and forming a fluid-tight seal with said spigot extension member at said first end, said filter housing threadably and rotationally attached to said right-angled neck portion, said right-angled neck portion threadably attached to said spigot extension member, said base portion in fluid communication with said right-angled neck portion, and having a plurality of apertures for fluid ingress to filter media enclosed within said filter housing, wherein said right-angled neck portion locates said base portion perpendicular from said extension member.

A housingless filter cartridge assembly for a gravity fed system, comprising:

• a handle having a handle end cap;
• a filter core member attached to, and in mechanical communication with, said handle end cap, and extending from said handle end cap to a lower end cap;
• said lower end cap attached to, and in mechanical communication with, said filter core member and having a connector for mating with a complementary manifold;
• and
• a cylindrical filter media having sidewalls circumferentially exposed to ingress fluid in the absence of a filter housing, and having an open axial center for receiving said filter core member in said axial center, and forming a sealing engagement with said handle end cap at one end and said lower end cap at the other end, wherein said cylindrical filter media is directly exposed to ingress fluid without an intermediate housing sidewall therebetween;
• such that when said handle is rotated, said handle end cap and said lower end cap are correspondingly rotated mating said lower end cap with said manifold.
