1. The apparatus for filtering and dispensing drinking water comprising:
a container having an interior space with a dividing wall defining a first chamber for receiving unfiltered water and a second chamber for storing filtered drinking water, wherein a passage is formed through the dividing wall adjacent a bottom surface of the container to provide fluid communication between the first chamber and the second chambers, and wherein at least one removable multi-layered filter pack is disposed across the passage to filter water flowing from the first chamber to the second chamber under force of gravity; and
a pre-filter seated in a well formed above the first chamber for removing relatively large particulates from the water introduced into the first chamber upstream from the at least one removable multi-layered filter pack.
