Abstract
In at least some embodiments, a filter comprises a filtering media. The filtering media is impregnated with chemical compounds that effectively retain water molecules and water-alcohol molecules but not alcohol molecules. The filter also comprises a liquid channeling structure, wherein the liquid channeling structure directs liquid entering an input of the filter to flow through the filtering media before exiting an output of the filter.
