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.

What is claimed is: 1. A filtering media, comprising: a particle-filtering material; a second material; and a water-absorbing structure between the particle-filtering material and the second material, the water-absorbing structure is based on a dual-valence polymer having negative valence monomer groups and positive valence monomer groups. the negative valence being stronger than the positive valence. 2. The filtering media of claim 1 wherein the monomer groups are synthetically produced to resist biodegradation due to life forms found in water. 3. The filtering media of claim 1 wherein the dual-valence polymer enables the water-absorbing structure to substantially retain water-bonded molecules. 4. The filtering media of claim 1 wherein the monomer groups are crossed-linked. 5. The filtering media of claim 1 wherein the monomer groups comprise at least one of a group consisting of carboxylate, sulfate, phosphate, sulfonates, phosphonates, propenoic acids, alpha-methyl-propenoic acids, beta-methyl-propenoic acids, poly-acrylic acids, acrylic acids, maleic acids, fumaric acids, maleic anhydrides, fumaric anhydrides, alpha-ethylenically unsaturated mono-carboxycilic acids, beta-ethylenically unsaturated mono-carboxycilic acids, alpha-ethylenically unsaturated di-carboxycilic acids, beta-ethylenically unsaturated di-carboxycilic acids, alpha-ethylenically unsaturated mono-carboxycilic anhydrides, beta-ethylen ically unsaturated mono-carboxycilic anhydrides, alpha-ethylenically unsaturated di-carboxycilic anhydrides and beta-ethylen ically unsaturated di-carboxycilic anhydrides. 6. The filtering media of claim 1 wherein the monomer groups comprise salts that are selected from a group of salts consisting of alkali ions, lithium ions, sodium ions and potassium ions. 7. The filtering media of claim 1 wherein the monomer groups comprise earth metals that are selected from a group of earth metals consisting of magnesium ions, calcium ions, strontium ions, barium ions, zinc ions and aluminum ions. 8. The filtering media of claim 1 wherein the water-absorbing structure further comprises a fiber-glass matting impregnated with the dual-valence polymer. 9. The filtering media of claim 1 wherein the filtering media is used to remove water molecules and water-bonded molecules from alcohol-based fluids, hydrocarbon-based fluids, or combinations thereof. 10. A filter, comprising: a particle-filtering material; a second material; a water-absorbing media between the particle-filtering media and the second material, the water-absorbing media is impregnated with a dual-valence chemical composition that substantially retains water molecules and water-bonded molecules within the filtering media; and a fluid channeling structure, wherein the fluid channeling structure directs fluids entering an input of the filter to flow through the particle-filtering material and the water-absorbing media before exiting an output of the filter. 11. The filter of claim 10 wherein the dual-valence chemical composition comprises negatively-charged monomer groups and positively-charged monomer groups, wherein the negative charge is stronger than the positive charge. 12. The filter of claim 10 wherein the fluid channeling structure comprises a perforated element and wherein the particle-filtering material, the water-absorbing media, and the second material surround the perforated element in a pleated arrangement. 13. The filter of claim 12 further comprising an outer sheath, wherein the pleated arrangement is configured to expand between the perforated element and the outer sheath. 14. The filter of claim 13 wherein, if the water-absorbing media retains a threshold amount of water molecules and water-bonded molecules, the pleated arrangement expands and prevents pressurized fluid from flowing though the filtering media. 15. The filter of claim 10 wherein the filter is configured for use in at least one of a fuel dispensing system that dispenses alcohol-blended fuel, a vehicle that burns alcohol-blended fuel, and a portable unit that filters alcohol-blended fuel from a fuel tank, the alcohol-blended fuel having up to eighty-five percent alcohol. 16. The filter of claim 10 wherein the filter is applied to alcohol-based fluids in which water is a contaminant. 17. The filter of claim 10 wherein the filter is applied to hydrocarbon-based fluids in which water is a contaminant. 18. A method, comprising: Impregnating a filtering media with a dual-valence polymer derived from non-naturally occurring monomers that exhibit negative charges and positive charge, wherein the negative charges are stronger than the positive charges to enable substantial retention of water molecules and water-bonded molecules within the filtering; media; and forming a pleated arrangement with the filtering media and enclosing the pleated arrangement in a space between a perforated element and an outer sheath, the space enabling the pleated arrangement to expand until a threshold amount of water and water-bonded molecules is retained. 19. The method of claim 18 further comprising using the filtering media to substantially remove water molecules and water-bonded molecules from alcohol-based fluids, hydrocarbon-based fluids, or combinations thereof.
