A water treatment apparatus includes a housing comprising multiple housing portions and a plurality of treatment sections disposed within the housing, each treatment section comprising at least one distinct particulate layer. The apparatus is designed so that no water pressure need be applied to force the water through the apparatus, as gravity pulls the water down through the filtering layers. Water may also be force fed through the treatment apparatus; when the water is force fed, the housing portions need not be vertically stacked, but may be configured in any suitable arrangement. The treatment sections are distributed through the various housing portions in logical groups to perform various kinds of filtering. The housing portions are detachable and sealably stackable in multiple configurations, thus passing water through more or fewer treatment layers, depending on the quality of the incoming water.

Having, thus, described the present invention, what is claimed is: 1. A fluid treatment apparatus, comprising: a housing including an inlet, an outlet, and layers of filtration material, the layers of filtration material layers, comprising: (a) an activated carbon layer; (b) a redox alloy layer; and (b) an ion exchange resin layer. 2. The fluid treatment apparatus of claim 1, wherein the activated carbon layer further comprises redox alloy. 3. The fluid treatment apparatus of claim 1, wherein the activated carbon layer and ion exchange layer are mixed in the same layer. 4. The fluid treatment apparatus of claim 1, wherein the housing further comprises at least one porous separator arranged in the housing portion, wherein the at least one porous separator regulates water flow. 5. The fluid treatment apparatus of claim 1, wherein a bottom surface of the housing includes an outlet, wherein the outlet allows for a dwell time ranging from about 1 to 10 minutes. 6. The fluid treatment apparatus of claim 1, wherein the fluid is water and the apparatus has a dwell time sufficient for contacting water with the layers of filtration materials to produce potable water. 7. The fluid treatment apparatus of claim 1, further comprising a first and second porous separator, wherein the first porous separator is more porous than the second porous separator and the first porous separator is affanged closer to the inlet than the second porous separator. 8. The fluid treatment apparatus of claim 1, wherein the layers of filtration materials further comprise a filter paper layer affanged above and below the ion exchange resin layer. 9. The fluid treatment apparatus of claim 1, wherein the fluid is water and is feed into the apparatus by gravity. 10. The water treatment apparatus of claim 1, wherein the fluid is water and is fed into the apparatus by pressure. 11. The fluid treatment apparatus of claim 1, wherein a bottom surface of the housing contains a recess and an outlet wherein the size of the recess outlet is a factor in controlling dwell time of the fluid and the size is provided such that there is sufficient time for contacting the fluid with the layers of filtration materials to produce potable water. 12. A water treatment apparatus, the apparatus capable of discharging potable water therefrom, the apparatus comprising: a water reservoir capable of being connected to an unfiltered water source; a first filter housing arranged under the water reservoir and in fluid communication with the water reservoir; a second filter housing arranged under the water reservoir and in fluid communication with the water reservoir and the first filter having an outlet capable of exporting filtered water; and a receptacle to collect the filtered water and capable of being arranged in fluid communication with the water reservoir, first filter housing and second filter housing. 13. The water treatment apparatus of claim 12, wherein the first filter housing is removeably coupled to the second filter housing and the second filter housing is removably coupled to the receptacle. 14. The water treatment apparatus of claim 12, with all of its parts being self contained and usable alone or in conjunction with other dispensers if another outlet is contained within the filtered water receptacle. 15. A water treatment apparatus of claim 12, wherein the first housing is capable of being bypassed. 16. A water treatment apparatus, comprising: a first housing having a microbiological removal section for removal of microbiological contaminants; a second housing having inorganic, organic and radiological treatment section for removal of inorganic, organic and radiological contaminants; wherein the first and second housings are all detachable coupled and depending on the quality of water to be treated, either the first or second housing may be bypassed, thereby allowing water to pass through either the first or second housing. 17. A water treatment apparatus of claim 16, wherein the first housing comprises an inlet, cylindrical walls, and is affanged to substantially cover the second housing. 18. A water treatment apparatus, comprising an apparatus capable of removing inorganic and radiological contaminants from water with a plurality of particulate layers, the apparatus thereby capable of discharging potable water therefrom, the apparatus comprising: a housing having an inlet, an outlet, bottom surface of the housing contains an outlet having a size for providing a dwell time from about 1 to 10 minutes sufficient for contacting water with the plurality of particulate layers and produce potable water.
