The Franke 02 (previously known as FRX02® or FR9455) was the standard replacement filter cartridge for Franke filtration systems purchased prior to May 2011. Many thousands of users have benefited from the quality water it produces. The micro-porous ceramic outer shell, together with the hi-tech carbon core combine to provide superior performance across a wide range of possible waterborne contaminants, including sediment, harmful bacteria, parasites, cysts, chlorine and lead.
