Aries (AF-20-2014-BB) 20" x 4.5" (4 lb) KDF-55-GAC Filter
Core Performance Data
Filter Construction & Chemistry
| Manufacturer | Aries Filter Works |
| Primary Media | KDF-55 process media (high-purity copper-zinc alloy) |
| Secondary Media | Granular Activated Carbon (GAC) |
| Filtration Method | Oxidation-reduction (redox) + catalytic adsorption |
| Target Contaminants | Chlorine, heavy metals (lead, mercury, copper), hydrogen sulfide, taste, odor |
| Bacteriostatic Properties | KDF media inhibits bacteria, algae, and fungi growth in filter bed |
| Temperature Range | 40°F – 100°F (optimal performance) |
Where This Filter Works
The AF-20-2014-BB is designed for standard 20" x 4.5" Big Blue filter housings used in whole-house systems, well water applications, and commercial installations. The dual-media construction makes it ideal for municipal water with chlorine and heavy metal concerns, as well as well water requiring iron and hydrogen sulfide reduction when used with appropriate pre-filtration. KDF-55 extends the activated carbon's effective life by handling oxidizable contaminants first, allowing the GAC to focus on taste, odor, and organic compound removal. Compatible with most brands of Big Blue housings including Pentek, Culligan, and GE.
