A liquid filtration system, including an inclined filter support and a chimney, the chimney having an entrance adjacent an upper portion of the filter support; and a sheet filter supported in an inclined orientation by the inclined filter support. Air trapped by the sheet filter during use of the filtration system travels along a path corresponding to the inclined orientation sheet filter and into the entrance of the chimney for escape.

1. A liquid filtration system for use with a particulate filter medium, comprising: a treated liquid container and a liquid treatment container located substantially within the treated liquid container, the liquid treatment container being configured to receive untreated liquid for treatment therein

1. A liquid filtration system for use with a particulate filter medium, comprising: a treated liquid container and a liquid treatment container located substantially within the treated liquid container, the liquid treatment container being configured to receive untreated liquid for treatment therein and to yield treated liquid that is passed to the treated liquid container for storage and/or dispensing;the treated liquid container comprising a container having a bottom and a sidewall extending upwardly from the bottom;the liquid treatment container comprising a bottom having a drain, an upper section configured to receive a volume of liquid to be treated, and a particulate filter medium containing section within the liquid treatment container below the upper section and adjacent the bottom;a filter tray located within the upper section of the liquid treatment container and above the particulate filter medium containing section, the filter tray including an upper rim, an inclined filter support having an upwardly facing surface, and a chimney having an entrance, wherein the upper rim defines a plane that is, in use, oriented horizontally, wherein the upwardly facing surface of the filter support defines a plane that is inclined at an angle of inclination of from about 30 degrees to about 60 degrees relative to the plane of the upper rim, and wherein the entrance to the chimney is positioned below an uppermost portion of the upwardly facing surface of the filter support; anda sheet filter supported on the upwardly facing surface of the inclined filter support,wherein, liquid to be treated passes through the sheet filter supported by the filter tray, through the particulate filter medium, and exits the liquid treatment container to provide clean liquid stored within a lower portion of the treated liquid container, and air trapped by the sheet filter during use of the filtration system travels along a path corresponding to the inclined orientation sheet filter and into the entrance of the chimney for escape. 2. The system of claim 1, further comprising a sheet filter between the particulate filter medium and the bottom of the liquid treatment container to inhibit passage of the particulate filter medium through the drain. 3. The system of claim 1, further comprising a tube connecting between the drain and the interior of the treated liquid container to release treated liquid into the treated liquid container at a location elevated from the drain. 4. The system of claim 1, further comprising a sediment filter located above the filter tray, the sediment filter comprising a solid surface shaped to inhibit the passage of liquid therepast and to provide a surface onto which solids within liquid to be treated may settle and collect, the sediment filter further including a projection rising from the solid surface and having one or more apertures at an upper portion thereof to permit liquid to pass through the sediment filter at a level above the collected solids. 5. The system of claim 1, wherein the liquid comprises water and the clean liquid comprises drinking water. 6. The system of claim 1, wherein the particulate filter medium comprises sand. 7. A liquid filtration system, comprising: a filter tray including an upper rim, an inclined filter support having an upwardly facing surface, and a chimney having an entrance, wherein the upper rim defines a plane that is, in use, oriented horizontally, wherein the upwardly facing surface of the filter support defines a plane that is inclined at an angle of inclination of from about 30 degrees to about 60 degrees relative to the plane of the upper rim, and wherein the entrance to the chimney is positioned below an uppermost portion of the upwardly facing surface of the filter support; anda sheet filter supported on the upwardly facing surface of the inclined filter support,wherein, liquid to be treated passes through the sheet filter supported by the filter support, and air trapped by the sheet filter during use of the filtration system travels along a path corresponding to the inclined orientation sheet filter and into the entrance of the chimney for escape.
