| I am confused concerning the appropriate filter cartridge for my Culligan installed whole house system. I have narrowed the choices to the following: DGD-5005-20, DGD-7525-20 or DGD-2501-20. In the past I have just called Culligan and said , "Send me a Big Blue filter." What have they been sending me? Can you shed some light? |

| Bad taste is usually dealt with by a carbon filter of some sort. The 4.5" dimension is the diameter. See this cartridge for excellent carbon filtration with low pressure drop: RFC-20BB water filter and Pentek RFC20-BB carbon filters 155247 with granular activated carbon Thank you, WaterFilters.NET |
