A compact water purifier is described in which three filters are contained within a single container. The first filter in the sequence is a pre-filter designed to remove large particles from the flow stream, the second an activated carbon filter for the adsorption of toxic chemicals, and the third a ceramic microscreen, preferably containing silver or other bacteriostatic agent. The three filters are assembled within a cylindrical container which is sealed to the filter assembly at each end so that a substantially uniform inward flow pattern and stable f...
