The Culligan® Total Defense Cartridge offers the most comprehensive carbon filter we currently sell for the Aqua-Cleer® Advanced Drinking Water System. It acts as a last line of defense after the Reverse Osmosis or Nano Filtration membranes. The Culligan® Total Defense Cartridge is certified to remove contaminates that a RO cannot, such as Mercury, MTBE’s, VOC’s (Volatile Organic Chemical), PFOAs and PFOSs.

PFOAs and PFOSs are contained in a wide variety of commercial, industrial and residential products including fire-retarding foams, waterproofing, cleaning products, coating additives for non-stick cookware, and stain-resistant carpets. When PFOAs and PFOSs are spilled or improperly disposed of they can seep into the ground water and move into our water.


  • Certified to 1,000 gallons at .5 gpm
  • Reduces the following: Chloramine, Chlorine, Taste and Odor, Cyst, Lead, Nominal Particulate Class 1, Mercury, MTBE, Turbidity, VOCs (Volatile Organic Compounds), PFOAs and PFOSs


CAUTION: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.
