1. A filtering device for filtering running water from a pressurized water source, comprising: a housing with at least one running water inlet and at least one filtered water outlet;two or more water treatment modules disposed within the housing, each of which defines a water treatment space that holds at least one water treatment element for either removing a component from or adding a component to the water, and having a water ingress and a water egress, the running water inlet being linked and in flow communication with the water ingress of a first water treatment module, the water egress of a last water treatment module being linked and in flow communication with the filtered water outlet, the water egress of each of the modules other than the last water treatment module being linked and in flow communication with the water ingress of at least one other module, to thereby define a water flow path from the water inlet to the water outlet through a succession of the water treatment modules; and at least one of the modules (i) defines a curvilinear flow path in its water treatment space by two or more concentric cylindrical wall sections, at least one of the concentric cylindrical wall sections extends into the treatment space from a first wall and at least one other of the concentric cylindrical wall sections extends into the treatment space from an opposite wall, or (ii) comprises a corrugated or pleated filter sheet enveloping or being enveloped by another treatment element,wherein the modules are pre-assembled, stand-alone modules, the water egress of one or more of the modules being defined within a projection that is adapted to be received into a matching depression formed in another component of the filtering device, and the water ingress of one or more of the modules being formed in a depression adapted to receive a matching projection of another component of the filtering device, to thereby define the flow path. 2. The filtering device of claim 1, wherein the water treatment element comprises at least one component selected from the group consisting of a porous filtering element, a solid body of a filtering medium, an ion-exchange resinous medium, a particulate activated carbon medium, a particulate matter that includes a substance to be released into the water, and combinations thereof. 3. The filtering device of claim 1, wherein each of the modules independently comprises: (i) a single treatment element, or (ii) a combination of different treatment elements. 4. The filtering device of claim 1, wherein at least one direct flow water treatment module comprises a first water treatment element enveloping a lumen defined by a void within a solid porous filtering mass or by a perforated cylinder and surrounded by the treatment element, the lumen defining an axis;the first treatment element being enveloped by an entry space linked and in flow communication with the module's water ingress; andthe lumen being linked to the module's water egress;whereupon water flows in a general radial direction from the entry space to the lumen through the first treatment element. 5. The filtering device of claim 4, wherein the module egress is coaxial with the axis. 6. The filtering device of claim 4, wherein the treatment element is enveloped by a first corrugated or pleated sleeve. 7. The filtering device of claim 4, wherein the lumen comprises a second water treatment element which may be of the same or different substance(s) than that of the first water treatment element. 8. The filtering device of claim 1, wherein one or more modules snap fit into engagement with another module. 9. The filtering device of claim 1, wherein the housing comprises two or more sub-housing structures, each sub-housing structure housing one or more water treatment modules; andone or more linking elements connecting the sub-housing structures and having water conduits defined therein to permit water flow between said sub-housing structures along said flow path. 10. The filtering device of claim 9, wherein each of the sub-housing structures is an elongated element and the sub-housing structures being aligned with one another with the linking element being in normal orientation to that of said sub-housing structures. 11. The filtering device of claim 10, wherein the running water inlet and the filtered water outlet are formed within the linking element. 12. The filtering device of claim 1, wherein each water treatment module performs a different water treatment function. 13. The filtering device of claim 4, wherein the perforated cylinder is disposed within a compartment surrounded by the treatment element. 14. The filtering device of claim 1, comprising at least one serpentine flow type water treatment module having a water treatment space formed between two end walls opposite to one another and having a water ingress formed at substantially the center of a first of the two opposite walls; a curvilinear flow path being defined in the water treatment space by two or more concentric cylindrical wall sections, at least one of which extends into the treatment space from the first wall and at least one of which extends into the treatment space from the opposite wall; and the treatment space containing at least one water treatment element. 15. The filtering device of claim 14, wherein the water treatment element comprises at least one component selected from the group consisting of a porous filtering element, an ion-exchange resinous medium, a particulate activated carbon medium, a particulate matter that includes a substance to be released into the water, and combinations thereof.
