Multi-stage water filtration system

A multiple stage water filtration system for purifying tap water, the water filtration system comprising:

• a first adsorbent stage cartridge including filtering media comprising approximately 40-65 wt. % of silver-impregnated activated carbon, approximately 1-10 wt. % of activated alumina, approximately 15-35 wt. % of ceramic balls, approximately 0.5-1 wt. % of chitosan and approximately 0.5-1 wt. % of kinetic degradation fluxion media that includes zinc and brass;
• a second filtration stage cartridge including an antifouling electrospun nanofiber membrane, the antifouling electrospun nanofibers having a diameter from approximately 100 nanometers to 1 micron wherein the antifouling electrospun nanofiber membrane comprises a polyvinylidene fluoride base material, the base material being doped with polyacrylonitrile and including bacteria-repellent methoxy polyethylene glycol side chains such that the antifouling electrospun nanofiber membrane has a water contact angle of approximately 55 degrees or less;
• a flow path provided between the first adsorbent stage cartridge and the second filtration stage cartridge;
• the multiple stage water filtration system being capable of filtering water at a volume rate of at least approximately 2 liters per minute.
