Gravity-fed filter interconnect utilizing coded polymagnets

A filter cartridge for use in a gravity-fed filtration system, the filter cartridge comprising:

• a housing having a body with a sidewall, a top, and a bottom, and a longitudinal axis;
• a filter media disposed within the housing body;
• and
• a filter magnet disposed proximate to said housing body sidewall.

A method of initiating fluid flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system, comprising:

• providing said filter cartridge having a filter magnet;
• providing a holding reservoir for filtered fluid;
• providing a first reservoir having a recess receiving cavity in a bottom surface thereof for receiving ingress fluid;
• wherein said recess receiving cavity includes an aperture and carrier magnet moveable between a first position and a second position, said carrier magnet proximate said aperture;
• inserting said filter cartridge into said recess receiving cavity;
• moving the filter magnet to be in close proximity to said carrier magnet such that said filter magnet and said carrier magnet are in magnetic communication with one another to create a magnetic force;
• shifting said carrier magnet by said magnetic force to move said carrier magnet from said first position, initiating the blocking of fluid flow, to said second position, allowing for fluid flow to said holding reservoir.

A method of initiating fluid flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system, comprising:

• providing said filter cartridge having a bottom portion and a filter correlated polymagnet;
• providing a holding reservoir for filtered fluid;
• providing a first reservoir having a recess receiving cavity in a bottom surface thereof for receiving ingress fluid, said recess receiving cavity having a bottom portion with a movable carrier including a correlated polymagnet attached within, connected to, or proximate therewith, a sidewall, an aperture proximate said cavity bottom portion;
• inserting said filter cartridge into said recess receiving cavity;
• forming a magnetic shear force by bringing said filter cartridge correlated polymagnet in close proximity to said movable carrier correlated polymagnet;
• and
• moving said carrier by said magnetic shear force away from said aperture to allow for fluid flow from said filter cartridge to said holding reservoir.
