Filtration Process: The filter material in this filter is a selected coconut shell carbon block with 2x greater surface area and more micropores. Water passes through the filter's pores and is further purified through two separate ionization filtration stages as it passes through the carbon block to the refrigerator. Unlike cheaper hybrid carbon blocks, the filter material in the refrigerator filter improves the overall taste of the water.
