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.
