Abstract

A container includes a gable top fiberboard or cardboard carton having a top and a bottom, and may be substantially filled with drinking water. An activated carbon-containing integral mass of material (e.g. which may be present in various forms and quantities to suit the intended purpose, such as in accordion pleated sheet form, floating at or near the surface of the water, in a porous containing element, etc.) is disposed within the carton and is capable of removing more than 90% of the chlorine, lead or other taste and odor contaminants from the water in its optimized configuration. The carton top typically has a pour opening and the carbon containing mass may be fixed so that the water only comes into significant contact with the mass when the water is being (or about to be) poured through the opening. A biocidal media may also be disposed in the carton positively separated from the carbon containing mass by separator plates and/or ion exchange media. A fill port may also be provided on the carton top with a fill tube extending from the fill port to just above the bottom of the carton. Both the fill and pour openings may be capped by readily removable and replaceable caps. When the carbon containing material is a low density web it most desirably has a surface area of between about 1.25-2.75 square feet per half gallon capacity of the carton. In a tube configuration the carbon is about 5-60% resin and about 95-30% granular or powdered carbon.
