Reverse Osmosis Water Filters for Producing Water With Selectable Total Dissolved Solids

摘要

Methods and apparatus for providing water with a selectable total dissolved solids content. The apparatus includes a reverse osmosis filter system to provide filtered water having a dissolved solids content less than the selectable total dissolved solids content and for mixing water having a dissolved solids content exceeding the selectable total dissolved solids content with the filtered water in a ratio to provide water with the selectable total dissolved solids content. Various embodiments are disclosed.
