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. |
