An apparatus and method for the purification or water using a multistage purification system which can be connected to a source of potable water under pressure. The multistage purification system has a cylindrical pressure vessel supported on a circular leg which is capable of stable disposition on a level surface such as a countertop. The pressure vessel has a top member and a base member connected in sealed engagement. The base member has an inlet for receiving water into the pressure vessel and an outlet for discharging reject water from the pressure vessel. Housed within the pressure vessel is a plurality of purification mediums disposed in concentric disposition. In the core area of the pressure vessel, an interchangeable core member may be removably connected to the pressure vessel. Each interchangeable core member houses an additional medium for purifying water and a pure water outlet through which the purified water passes for use by the user. Influent water is purified by passing through a plurality of purification mediums before discharge for use. The purification capabilities of the system can be tailored to the user's need and a soiled or defective core member may be replaced without compromising the integrity of the system by simply changing interchangeable core members.

DETAILED DESCRIPTION In view of the foregoing needs and problems experienced by homeowners desiring water purification systems, it is a primary object of the present invention to provide an improved water purification system that can offer the homeowner the flexibility to purify water according to the homeowner's need by interchangeably introducing various types of purification mediums into the system or replacing soiled mediums, without compromising the integrity of the system, to accomplish the most efficient water purification for that homeowner's needs.
It is another object of the present invention to provide an apparatus which can be placed on a countertop near the faucet or tap from which the water is taken for treatment, such countertop purification system having its inlet and outlet connections proximate to one end of the system to reduce the need for significant plumbing.
A further object of the present invention is to provide an apparatus which is attractive and compact such that it occupies a minimum of countertop space and offers an outward appearance which is aesthetically pleasing to the homeowner.
Another object of the present invention is to provide an attractive pressure vessel so that the pressure vessel need not be contained within an additional housing to conceal an unsightly pressure vessel, interconnecting tubing and/or unsightly inlet and/or outlet connections.
Still another object of the present invention is to be configured to provide an enclosed storage compartment beneath the pressure vessel for storing the tubes and connections away from the homeowner's view, and wherein such configuration provides a stable base upon which the pressure vessel can securely rest upon a countertop or any level surface.
Yet another object of the present invention to provide multistage purification of water in a compact, appliance-like container to maximize purification capabilities while eliminating interconnecting tubing between purification stages and occupying a minimum of space
