Aries (AF-20-2211) 20"x2.5" (1 lb) KDF85-GAC Filter
Filter Specifications
| Model Number | AF-20-2211 |
| Dimensions | 20" x 2.5" |
| Media Composition | 1 lb KDF85 + Granular Activated Carbon (GAC) |
| Carbon Type | ResinTech Coconut Shell GAC |
| Primary Applications | Iron reduction, hydrogen sulfide removal, chlorine removal |
| Housing Compatibility | Standard 20" filter housings (2.5" diameter) |
| Bacteriostatic Properties | Yes, inhibits microbial growth in filter media |
How KDF85 and GAC Work Together
KDF85 is a high-purity copper-zinc redox alloy designed specifically for removing hydrogen sulfide and reducing dissolved iron through oxidation-reduction reactions and mechanical filtration. Unlike KDF55 (which targets chlorine and heavy metals in municipal water), KDF85 excels in well water environments where sulfur odors and iron staining are common. The granular activated carbon component provides broad-spectrum adsorption of organic contaminants, tastes, and odors, while the KDF85 extends the carbon's useful life by preventing premature fouling and limiting bacterial colonization within the filter bed.
Where This Filter Fits
The Aries AF-20-2211 is designed for whole-house or well water filtration systems using standard 20-inch housings. It works best as a specialty filter stage installed after sediment pre-filtration to address iron, hydrogen sulfide, and residual organics. This cartridge is not a sediment filter and should be protected by upstream filtration to prevent premature media fouling. Suitable for private wells, rural water supplies, and any application where redox chemistry offers a chemical-free alternative to chlorination or oxidizing agents.
