Felite™ FC311-PSM is a potable water grade, macroporous polyacrylic weak acid cation exchange resin with standard mesh size. It is specially processed for the drinking water system, consists of Hydrogen form and Sodium form Felite™ FC311-P at a special ratio, especially for those filters used in cafes, restaurants, and breweries. Its capability to selectively recover metal ions helps to retain useful ions such as Magnesium which helps extract fruit acids, and Bicarbonates provide a balance of taste and aroma to maintain the coffee’s flavor.
