Abstract

A gravity-driven water filtering system comprising: a gravity-driven water filter configured to engage and deliver treated water through apertures of various sizes and a filter receiving device. The gravity-driven water filter includes: a bottom portion; a water filter; and a top portion. The water filter is configured to be removably engaged by hand without the use of tools from the bottom portion and the water filter, the bottom portion and the top portion are each configured to be removably engaged and disengaged to allow for replacement of the filter and reassembly of the overall gravity filter assembly by hand and without the use of tools. The filter receiving device is a) a flat bottomed stand; b) a carrying device; or c) an adapter.

First claim

The invention claimed is:

1. A gravity-driven water filtering system comprising: a gravity-driven water filter configured to engage and deliver treated water through apertures of various sizes and a filter receiving device,
wherein the gravity-driven water filter comprises:
a bottom portion having at least one treated fluid outlet, an upper perimeter, and a bottom portion side wall that defines an interior volume of the bottom portion and wherein the bottom portion side wall is a shaped surface that is configured to frictionally engage a plurality of differently sized fluid vessel openings and still allow treated fluid to be delivered to the interior of a fluid vessel through the at least one treated fluid outlets;
a water filter comprising a fluid treatment medium positioned within the water filter wherein the filter is operably engaged with the bottom portion and having a fluid intake location and a fluid outgoing location that delivers treated fluid to the interior volume of the bottom portion and out of the at least one treated fluid outlet of the bottom portion; a top portion having an interior volume defined by at least one wall, at least one fluid inlet, and a bottom perimeter defining an opening and wherein the top portion is configured to received fluid from at least one fluid inlet and the bottom perimeter defines an opening that is configured to allow fluid from the at least one inlet to flow into contact with an intake surface of the water filter; and
wherein the water filter is configured to be removably engaged by hand without the use of tools from the bottom portion and the water filter, the bottom portion and the top portion are each configured to be removably engaged and disengaged to allow for replacement of the filter and reassembly of the overall gravity-driven water filter by hand and without the use of tools; and
wherein the filter receiving device comprises a filter receiving device chosen from the group consisting of:
a) a flat bottomed stand that receives the top portion of the gravity-driven water filter where the stand has a top portion receiving center section insert that has the same shape as the top portion such that the top portion matingly engages the top portion receiving center section insert and wherein the top portion receiving center section insert is detachable from a perimeter stand portion positioned about a perimeter of the top portion receiving center section insert when engaged therewith;
b) an adapter configured to either (1) provide an ability for the gravity-driven water filter to deliver treated water to a vessel having a aperture larger than the width of the gravity-driven water filter or (2) engage a side wall of the vessel and suspend the gravity-driven water filter from a side wall over an aperture larger than the width of the gravity-driven water filter.

2. The gravity-driven water filtering system of claim 1 , wherein the top portion receiving center section insert is removable and a metal material with a plurality of apertures configured to allow draining of water from within the gravity-driven water filter into a space under the top portion receiving center section; and wherein the water filter further comprises a perimeter sidewall within the water filter; wherein the top portion of the fluid filter seals the filter treatment medium within the water filter.

3. The gravity-driven water filtering system of claim 2 , wherein the top portion receiving center section insert has a plurality of apertures radially aligned extending away from a center aperture that is larger than the other apertures.

4. The gravity-driven water filtering system of claim 1 , wherein the filter receiving device is an adapter that engages the side wall of the vessel and the adapter includes a vessel suspension system integrated with the bottom portion that is moveable between a retracted closed position where the perimeter conforms at least substantially with an exterior shape of the bottom portion and an open vessel engaging position wherein the vessel suspension system is connected to the bottom portion by a hinge.

5. The gravity-driven water filtering system of claim 1 , wherein the filter receiving device is an adapter that engages the side wall of the vessel and the adapter is a vessel suspension system integrated with the bottom portion that is moveable between a retracted closed position and an open vessel engaging position where the vessel suspension system spans a filling aperture of the vessel across opposing sides of the vessel and wherein the vessel suspension system includes two opposing curved sections configured to be pulled away from the bottom portion and hold the gravity-driven water filter in a substantially central position over the opening of the vessel but the curved sections are each operably connected to the bottom portion by a bridging support member.

6. The gravity-driven water filtering system of claim 1 , wherein the filter receiving device is a filter suspension device that is separate from the gravity-driven water filter wherein the filter suspension device includes at least two laterally extending planar members that extend away from a center filter receiving aperture and are rotatably connected to one another about the center filter receiving aperture.

7. The gravity-driven water filtering system of claim 6 , wherein the ends of the laterally extending planar members each have an aperture that at least substantially align when the laterally extending planar member are aligned over one another.

8. The gravity-driven water filtering system of claim 7 , wherein the filter receiving device is a stand that includes a base and an upwardly extending shelf support wall that extends upward to a planar shelf that is at least substantially parallel to the base and has at least one filter receiving aperture that receives the filter above a vessel loading location.

9. The gravity-driven water filtering system of claim 1 , wherein the fluid treatment medium is a water treatment medium configured to treat water at a rate of at least about one liter per minute while removing at least chlorine odor and chlorine taste components from the water.

10. The gravity-driven water filtering system of claim 1 , wherein the filter is at least partially positioned within the bottom portion.

11. The gravity-driven water filtering system of claim 1 , wherein the bottom portion side wall is a funnel shape with a funnel outlet portion having the at least one treated fluid outlet that is at least one treated water outlet.

12. The gravity-driven water filtering system of claim 1 , wherein the fluid intake location of the water filter is an at least substantially planar surface with apertures between structural support spokes that extend between a hub and a perimeter of the at least substantially planar surface of the fluid intake location and the fluid outgoing location is an at least substantially planar surface with apertures between structural supports that extend between a hub and a perimeter of the at least substantially planar surface of the fluid outgoing location.

13. The gravity-driven water filtering system of claim 12 , wherein the apertures of the at least substantially planar surface are apertures between structural supports that extend between a hub and a perimeter of the at least substantially planar surface of the water outgoing location.

14. The gravity-driven water filtering system of claim 1 , wherein the fluid treatment medium is a water treatment medium that reduces chlorine taste and odor components (CTO) per NSF 42 to a minimum of 60 gallons and wherein the gravity-driven water treatment medium allows for
