Aries (AF-20-2085) 20"x2.5" KDF-85 Filter

The Aries AF-20-2085 is a 20-inch by 2.5-inch specialty cartridge that combines coconut shell granular activated carbon with KDF-85 media to tackle hydrogen sulfide and iron in well water and whole-house applications. This dual-media design uses redox filtration to remove contaminants while inhibiting bacterial growth inside the filter housing.

COMPATIBILITY

Housing Requirements

The AF-20-2085 fits any standard 20-inch filter housing with a 2.5-inch inner diameter. This cartridge is designed for well water and whole-house systems where hydrogen sulfide odor or iron staining is a concern. KDF-85 media works best in applications with pH levels between 6.5 and 8.5, and performs optimally when water temperature is above 60°F. Not recommended for chlorinated municipal water as primary filtration; use KDF-55 media cartridges for chlorine removal instead.

🔧 Pro tip: If you're dealing with high iron levels (above 3 ppm), consider installing a sediment pre-filter upstream of the AF-20-2085 to capture oxidized iron particles and extend the life of the KDF media. Replace the cartridge every 6 to 12 months depending on water quality and usage.
