## Abstract

A water filtration assembly is provided including a bottom fluid container having a floor portion, an open top portion, and a sidewall. The sidewall defines an inwardly extending filter assembly support surface. At least one fluid container segment is provided for vertically stacking and engagement to the bottom container and other container segments. The fluid container segments also define an inwardly extending fluid assembly support surface. A first filter assembly for removing contaminates is disposable within the bottom fluid container, supported by the bottom container filter assembly support surface. At least one second filter assembly for removing contaminates is disposable within the container segment(s), supported on the container segment filter assembly support surface.

## Claims

### Claim 1

A water filtration assembly comprising:
a bottom fluid container having a floor portion, an open top portion and a sidewall;
the bottom container sidewall defining an inwardly extending filter assembly support surface disposed intermediate the bottom container floor portion and the bottom container open top portion;
at least one fluid container segment having an open bottom portion, an open top portion and a sidewall formed for vertically stackable engagement to the bottom container and other container segments;
the fluid container segment(s) further defining an inwardly extending filter assembly support surface disposed intermediate the container segment open bottom portion and the container segment open top portion;
a first filter assembly for removing contaminates from a fluid, the first filter assembly being disposable within the bottom fluid container, supported by the bottom container filter assembly support surface; and
at least one second filter assembly for removing contaminates from a fluid, the second filter assembly being disposable within the at least one container segment, supported on the container segment filter assembly support surface.

### Claim 2 (depends on 1)

The water filter assembly as recited in claim 1 wherein the bottom container further includes a rim extending about the open top portion of the bottom container.

### Claim 3 (depends on 2)

The water filter assembly as recited in claim 2 wherein the at least one container segment defines a pair of handles formed on an outer surface of the container segment, such that upon stacking the container segment upon the bottom container the handles abut against the bottom container rim to support the at least one container segment and to provide vertical spacing between first filter assembly and the second filter assembly.

### Claim 4 (depends on 3)

The water filtration assembly as recited in claim 3 further comprising a plurality of stackable fluid containers segments and a corresponding plurality of second filter assemblies, each container segment including a container segment filter assembly support surface supporting an associated second filter assembly.

### Claim 5 (depends on 4)

The water filter assembly as recited in claim 4 wherein each of the container segments defines a rim about the container segment open top portion and a pair of handles formed on an outer surface of the container segments, such that upon stacking the container segments upon each other the handles abut against the rim of an adjacent container segment to support the container segments and to provide vertical spacing between the respective container segment second filter assemblies.

### Claim 6 (depends on 3)

The water filter assembly as recited in claim 3 wherein the bottom container filter assembly support surface comprises an inwardly extending circumferential rim formed on an inner surface of the bottom container.

### Claim 7 (depends on 6)

The water filter assembly as recited in claim 6 wherein each container segment filter assembly support surface comprises inwardly extending circumferential rim formed on an inner surface of each fluid container segment.

### Claim 8 (depends on 3)

The water filter assembly as recited in claim 3 wherein the bottom container filter assembly support surface comprises at least one inwardly extending protrusion formed on an inner surface of the bottom container.

### Claim 9 (depends on 8)

The water filter assembly as recited in claim 8 wherein the container segment filter assembly support surface comprises at least one inwardly extending protrusion formed on an inner surface of each container segment.

### Claim 10 (depends on 1)

The water filter assembly as recited in claim 1 wherein the first and second filter assemblies are commonly formed.

### Claim 11 (depends on 1)

The water filter assembly as recited in claim 1 wherein the first filter assembly includes a filter membrane.

### Claim 12 (depends on 4)

The water filter assembly as recited in claim 4 wherein the first filter assembly further includes a filter membrane support surface, supported by the bottom container filter assembly support surface and supporting the filter membrane.

### Claim 13 (depends on 11)

The water filter assembly as recited in claim 11 wherein the second filter assembly includes a filter membrane.

### Claim 14 (depends on 12)

The water filter assembly as recited in claim 12 wherein the second filter assembly further includes a filter membrane support surface, supported by the container segment filter assembly support surface and supporting the filter membrane.

### Claim 15 (depends on 5)

The water filter assembly as recited in claim 5 wherein the bottom container is a cylindrical trash can.

### Claim 16 (depends on 15)

The water filter assembly as recited in claim 15 wherein each container segment is a truncated cylindrical trash can.

### Claim 17 (depends on 11)

The water filter assembly as recited in claim 11 wherein the container filter membrane is formed as a paper filter.

### Claim 18 (depends on 5)

The water filter assembly as recited in claim 5 wherein at least one of the first and second filter assemblies includes a filtration media.

### Claim 19 (depends on 18)

The water filter assembly as recited in claim 18 wherein the filtration media is selected from the group of:
activated carbon; and
a mixture of cooper and/or zinc granules.

### Claim 20 (depends on 19)

The water filter assembly as recited in claim 19 wherein the filtration media is operative to filter chlorine, chloramine, iron, bacteria, algae, fungus, hydrogen sulfide, and heavy metals.

### Claim 21 (depends on 20)

The water filter assembly as recited in claim 20 wherein the contaminates include arsenic, chlorine, chloramines, cryptosporidium, fluoride, lead, mercury, nitrate, cadmium, and bacteria.
