Emma, the granddaughter of Jim and Tricia Feijo, was the impetus behind Jim's search for this cartridge filter design. He wanted a filter that would effectively remove fluoride as well as chlorine and other contaminants from tap water, but that would leave the God-created minerals intact. His search ultimately proved successful – hence, the WATERKLEEN™ FRS "Emma Filter" can be yours, promising economical, convenient, and CLEAN water in your home -- just as God intended it!
