A filter for removing soluble, colloidal, and insoluble particles from a fluid, including lead using a first filter media for filtering soluble mater ial from the fluid, a second filter media, adjacent and in fluid communicati on with, the first filter media, for filtering soluble material from said fl uid, wherein the first and second filter media create a physical non-soluble particle barrier at their interface for capturing non-soluble particles, th at when retained at the interface, become soluble over time in the fluid, an d are subsequently removed by the second filter media. At least one of the f ilter media can be fibrillated nanofibers that are loaded with finely subdiv ided media of powdered ion exchange resins. A third filter media may be plac ed between the first and second filter media to enhance capturing and dissol ving the physical non-soluble particles. |
