Claim Text:
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; and a 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.
