Water conversion device

1. A water filter for gravitationally filtering water from an upper collecting chamber above the filter into a filtered water lower collecting chamber below the filter, the filter comprising:

an upper shell having circular ridges; and

a lower shell having circular crevices containing water treatment reactants, the lower shell having one or more water outlets in a bottom portion of the shell, wherein said upper shell is superimposed upon and matched with said lower shell, thereby forming a filter element with a circular water inlet at a top side thereof and defining a serpentine water flow path from said inlet to the one or more water outlets at a bottom side thereof.

2. The filter of claim 1 , wherein the upper shell circular ridges extend into spaces formed by the lower shell circular crevices.

3. The filter of claim 2 , wherein the circular water inlet is located along a periphery of the top side of the filter and the one or more water outlets are located in a central part of a bottom side of the filter.

4. The filter of claim 3 , wherein the upper shell circular ridges and the lower shell circular crevices are concentric.

5. The filter of claim 1 , wherein the water treatment reactants are configured to convert source water into potable water.

6. A potable water container comprising the filter of claim 5 .

7. A potable water container, comprising:

a potable water reservoir with a sealable dispensing outlet;

the filter of claim 5 , fitted within a lower part of the water container such that the water outlet of said filter opens into the potable water reservoir; and

a water receptacle for introducing source water and feeding it to the filter.

8. The potable water container of claim 7 having a water filtering position in which the source water can be introduced into the water receptacle, the introduced water can then filter through said filter for conversion into potable water, and the potable water can accumulate in the reservoir.

9. The potable water container of claim 8 , wherein the container is portable.

10. The portable potable water container of claim 9 , further comprising an air vent for venting the reservoir while filtering.

11. The portable potable water container of claim 9 , wherein said potable water reservoir has a compressed state in which the reservoir is compacted adjacent said top side and an extended state in which the reservoir is expanded.

12. A water filter for gravitationally filtering water, the filter comprising:

an upper shell having a plurality of ridges; and

a lower shell having a plurality of crevices containing water treatment reactants and having one or more water outlets at a bottom portion of the shell;

said upper shell superimposed upon and matched with said lower shell such that said ridges at least partially extend into said crevices to form a filter element having a water inlet on a top side thereof, one or more water outlets on a bottom side thereof, and a serpentine water flow path through said water treatment reactants along said plurality of ridges and crevices from said inlet to said one or more outlets.

13. The filter of claim 12 , wherein the inlet is located along a periphery of the top side of the filter and the one or more water outlets are centrally located in the bottom side of thefilter.

14. The filter of claim 12 , wherein the ridges, crevices, and water inlet are circular.

15. The filter of claim 14 , wherein the ridges and crevices are concentric.

16. The filter of claim 12 further comprising an upper collecting chamber above the filter for receiving source water and a lower collecting chamber below the filter for receiving potable water.

17. A portable water container comprising the filter of claim 16 .

18. The portable water container of claim 17 , wherein at least one of the lower collecting chambers or the upper collecting chamber are collapsible.
