Abstract
A gravity-fed filtration system and method of initiating flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system. The method comprises providing a filter cartridge having a filter magnet, a holding reservoir for filtered fluid, and a first reservoir having a recess receiving cavity in a bottom surface thereof for receiving ingress fluid. Upon inserting the filter cartridge into the recess receiving cavity and moving the filter magnet to be in in magnetic communication with the carrier magnet, a magnetic force moves the carrier magnet from a first position which blocks fluid flow, to said second position which allows fluid flow to the holding reservoir.
Claims12
A method of permitting fluid flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system, comprising:
- inserting said filter cartridge into a recess receiving cavity of a first reservoir for receiving ingress fluid, said recess receiving cavity including an aperture and a carrier proximate thereto, said carrier moveable between a first position and a second position and including a carrier magnet;
- moving a filter magnet of said filter cartridge 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 generate a magnetic field force therebetween;
- moving said carrier by said magnetic field force from said first position, blocking fluid flow, to said second position, allowing for fluid flow, to said holding reservoir for filtered fluid.
