A water purifier for treating water intended for drinking and like purposes, for installation at point-of-use, i.e., home, office or workplace, which is effective in removing additional contaminents therefrom using a heated carbon filter and distillation, in which the water being purified is heated and induced to alternately flow back and forth between an open compartment used for the filter and a closed evaporator in which it is distilled, the intervals of flow into the filter compartment being effective to heat the filter to thereby increase its ability to remove heavy molecular pollutants (e.g., pesticides, herbicides, etc.) and also being an advantageous location from which there is released to atmosphere low molecular volatile pollutants (e.g., certain hydrocarbons, the trihalomethanes, and other volatile organic compounds), and the succeeding intervals of flow into the evaporator completing the purification process by causing the removal, by distillation, of undesirable dissolved minerals and metals in the steam forced from the evaporator into a condenser preparatory to a change in phase to water for drinking and like uses.

A method of separating by evaporation hydrocarbons from drinking water using a heated activated carbon filter comprising the steps of establishing communication through a fluid connection between an evaporator closed to atmosphere and a compartment having said activated carbon filter, flowing under pressure said drinking water through said activated carbon filter and from thence in a first direction through said fluid connection from said activated carbon filter compartment into said closed evaporator, causing by evaporation in said closed evaporator the production of steam from said drinking water which is partially channelled into a condenser for a phase change back to fluid incident to being used as purified drinking water, allowing a remaining portion of said produced steam in said closed evaporator to force the heated drinking water therein to flow in a reverse second direction through said fluid connection from said closed evaporator back into said activated carbon filter compartment for establishing physical contact with the exterior of said activated carbon filter, and causing by heat exchange between said back flowing heated drinking water and said activated carbon filter the heating of said filter, whereby said drinking water being forced under pressure through said filter is exposed to said heated activated carbon which enhances the filtering of hydrocarbons therefrom.
