ABSTRACT:
A filter cartridge for water purification consisting of several layers of filter material with successively smaller pore size. The outer layer is a prefiltration material with a pore size of approximately 10 microns, the central layer is an extruded carbon filter with a pore size of approximately 5 microns, and the inner layer is a ceramic filter with a pore size of approximately 0.9 microns. The extruded carbon layer of the filter is impregnated with a chemical agent to effect the removal of lead and other heavy metals, while the ceramic layer has been impregnated with silver to prevent bacterial buildup. The filter cartridge provides almost complete removal of chlorine, organic compounds, lead, heavy metals, particulate matter and microorganisms.
