Abstract

A gravity based water purifier is disclosed. The said gravity based water purifier comprises an outer casing defining a purifier inlet for receiving water to be purified and a purifier outlet for outflow of purified water. The outer casing further defines a receptacle for receiving a cartridge holding a purification medium, a cavity for receiving an end of life assembly and a passage for providing a fluid communication under gravity between the purifier inlet and the cartridge. Herein, the cartridge defines a top surface and a bottom surface and includes a cartridge inlet positioned proximate the bottom surface for receiving water to be purified from the purifier inlet through the passage and a cartridge outlet positioned proximate the top surface for delivering the purified water therefrom, such that the water to be purified flows in an upward direction through the purification medium in the cartridge. The end of life assembly comprises an assembly inlet and an assembly outlet, the assembly inlet positioned proximate the cartridge outlet and configured to receive the purified water therefrom, the assembly outlet positioned proximate the purifier outlet, such that the purified water flows downward unidirectionally under gravity through the end of life assembly before exiting the water purifier through the purifier outlet.
