Pentek sediment and carbon cartridges for standard and Big Blue filter housings.

Reading the part number

  • BB means Big Blue: a 4.5 in diameter cartridge. Without BB the cartridge is the standard 2.5 in diameter.
  • -20 at the end means 20 in long; otherwise the cartridge is about 10 in.
  • Media. DGD is dual-gradient sediment, RFC is radial-flow carbon, and CBC and EP are carbon block.
  • Example. RFC-BB is a radial-flow carbon cartridge for a 10 in Big Blue housing.

All types: water filters and cartridges.
