a lidded opening positioned within said lid serving as a port for the introduction of water to be filtered by said device and fitted with a strainer for the removal of any debris in said water; a spigot attached to the outer surface of said lateral side; a two-part filtration unit positioned on the inner surface of said lateral side, threadably attached to, and in fluid communication with, said spigot, said filtration unit having a ceramic filter and an activated charcoal filter; and a hand-activated pump attached to said removable lid to pressurize water within said device, forcing said water through said filtration unit and into said spigot by which said filtered water can be removed from said device. ### Claim 2 (depends on 1) The water filtration device according to claim 1 wherein said ceramic filter has a pore size of between 0.2 and 0.3 microns. ### Claim 3 (depends on 1) The water filtration device according to claim 1 wherein said activated charcoal filter is positioned between said ceramic filter and said spigot. ### Claim 4 (depends on 1) The water filtration device according to claim 1 wherein said lid of said lidded opening engages with said opening in a friction fit. ### Claim 5 (depends on 1) The water filtration device according to claim 1 wherein said lid of said lidded opening engages with said opening in a threaded fit. ### Claim 6 (depends on 1) The water filtration device according to claim 1 wherein said two-part filtration unit is threadably attached to a filter housing. ### Claim 7 (depends on 1) The water filtration device according to claim 1 wherein said ceramic and activated charcoal filters are threadably attached. ### Claim 8 (depends on 1) The water filtration device according to claim 1 further including a handle. ### Claim 9 (depends on 1) A method of filtering untreated water employing a device according to claim 1 which comprises: pouring water through said lidded opening serving as a port for the introduction of water to be filtered and straining for the removal of debris; closing said lidded opening; activating said hand-pump to pressurize said water in said air-tight container; and opening said spigot to urge said pressurized water through said two-part filtration unit and into said spigot for removal from said device.
