Aries (AF-20-2212) 20" x 2.5" (2 lb) KDF-85-GAC Filter

The Aries AF-20-2212 combines 2 pounds of KDF-85 media with coconut shell granular activated carbon in a 20" x 2.5" cartridge designed for iron, hydrogen sulfide, and heavy metal reduction in well water and whole-house systems. This dual-media filter uses redox technology to extend filter life while inhibiting bacterial growth inside the cartridge.

INSTALLATION & USE

Filter Replacement Process

  1. Shut off water supply and relieve system pressure using the housing's pressure release button or valve.
  2. Unscrew the filter housing using a housing wrench, remove the old cartridge, and clean the housing interior and o-ring with warm water.
  3. Insert the Aries AF-20-2212 cartridge into the housing, ensuring it seats properly on the center post, then hand-tighten the housing back onto the cap.
  4. Turn water supply back on slowly and check for leaks, then flush the filter for 3-5 minutes to remove carbon fines and activate the KDF media.
COMPATIBILITY

System Fitment

The AF-20-2212 fits all standard 20-inch filter housings with 2.5-inch inner diameters. This filter is specifically formulated for well water applications where iron, hydrogen sulfide (rotten egg odor), and heavy metals are present. The KDF-85 media targets iron and sulfur compounds through oxidation-reduction reactions, while the granular activated carbon addresses taste, odor, and chlorine in blended water sources. Not recommended as a sole treatment for high iron concentrations above 5 ppm without pre-filtration.

🔧 Pro Tip: KDF-85 media performs best when water temperature is above 50°F and pH is between 6.5-8.5. If you're treating well water with high iron content, install a sediment pre-filter upstream to capture particulate iron and prevent premature clogging of the KDF-GAC cartridge.
