Shower filter element

A method of filtering shower bathing water comprising the steps of:

• providing a cylindrical shower filter element including:
• a filter assembly, an upper end cover and a lower end cover which are located at opposing ends of the filter assembly, wherein the upper end cover and the lower end cover are detachably connected to the filter assembly;
• an outermost first-stage filter element composite layer including an inner support layer, at least one micron pore size filter layer having pores ranging from 10-30 microns, and an outer support layer;
• a second-stage filter element composite layer including a support filter layer and a composite carbon fiber layer, the composite carbon fiber layer comprises a carbon fiber layer and a wrapping filter layer wrapping a surface of the carbon fiber layer, the support filter layer defines a cylindrical structure;
• an innermost third-stage filter element component including a filter container and a filter material arranged in the filter container;
• attaching the cylindrical shower filter element between a shower head and a shower water delivery conduit such that water may sequentially flow therethrough;
• and
• flowing water through the shower water delivery conduit, sequentially through each stage of the cylindrical shower filter element, delivering purified water to the shower head to be dispensed therefrom.
