NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. NOTE: CBC-20BB filter cartridges will contain a very small amount of carbon fines (very fine black powder) and a new cartridge after installation should be flushed with sufficient water to remove all traces of the fines from your water system before using the water. Each time you use your filtered water tap for drinking or cooking purposes it is recommended that you run (flush) the tap for at least 20 seconds prior to using water. NOTE: Micron ratings based on 85% or greater removal of given particle size. NOTE: CBC-20BB filter cartridges are capable of reducing 99.95% of cryptosporidium and giardia cysts. Data obtained from actual particle counts using AC Fine Test Dust and Latex spheres. CBC Series cartridges say 'Not for residential sale in the state of California' on the filter label because they have not been submitted to California for testing. This is an expensive testing process that Pentair has chosen not to undergo at this time in order to keep the cost of the filters down. Nominal 0.5 micron Pentek CBC20-BB Carbon Briquette Water Filter Cartridges have enhanced dirt-holding capacity.
