  • Water-filtering media and filters
    Patent number: 8187474
    Abstract: In at least some embodiments, a system for removing contaminants from fluids includes a fluid inlet and a fluid outlet. The system also includes a fluid pump between the fluid inlet and the fluid outlet and a filter material between the fluid inlet and the fluid outlet. The filter material comprises a dual-valence polymer with negative valence monomer groups and positive valence monomer groups, the negative valence being stronger than the positive valence.
    Type: Grant

  • Water-filtering media and filters
    Patent number: 7425266
    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.
