Abstract

A gravity based water purifier is disclosed. The gravity based water purifier comprises an outer casing defining an inlet for receiving water to be purified, a recess to receive a cartridge holding a purification medium, a cavity to receive an end of life chamber, a passage connecting the cavity to the recess, and a purifier outlet. The purifier also includes a cartridge holding a purification medium defining a top and bottom surface and including a cartridge inlet for receiving water to be purified positioned proximate the bottom surface and a cartridge outlet for purified water also positioned proximate the bottom surface, the cartridge further includes an outlet passage for conveying water exiting the purification medium to the cartridge outlet. The cartridge is configured to be received in the recess such that a recess chamber is defined there between, an accumulation chamber is formed between the cartridge and the outer casing and the cartridge outlet is in fluid communication with the purifier outlet. An end of life chamber is placed in the cavity and includes an inlet in fluid communication with the accumulation chamber and an outlet in fluid communication with the recess chamber via the passage. The end of life chamber further containing at least one water soluble tablet and a plunger with a plug configured to close the inlet or the outlet of the end of life chamber when the water soluble tablet is dissolved after a predetermined amount of water passes through the water purifier, such that water entering the water purifier through the inlet in the outer casing travels through the end of life chamber to the cartridge and passes through the cartridge in a upward flow before exiting from the water purifier.
