Filtration Process: The filter uses 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 flows through the carbon block to the refrigerator. Unlike cheaper hybrid carbon blocks, this filter enhances water taste.
