What is the difference between the Pentek CBR2-10 and Pentek CBR2-10R Water Filter Cartridge? The Pentek CBR2-10R has a built-in flow restrictor (0.6 gpm) to allow for maximum contact time. The Pentek CBR2-10 does NOT have this flow restrictor. The Pentek CBR2-10 water filter has a higher flow rate than the Pentek CBR2-10R water filter. Since the flow rate is restricted, the Pentek CBR2-10R filter is better for undersink drinking water systems and not whole house systems.
Why are the Pentek CBR2-10 and Pentek CBR2-10R Water Filter Cartridges marked 'Not for residential sale in the state of California'? CBR2 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. This item cannot be shipped to California
