ResinTech, formerly known as Aries, Tannin filter cartridges use ResinTech® SBACR anion exchange resin to reduce tannins and other organic compounds. This helps improve water color, taste, and odor. Tannins are natural organic compounds that can give water a yellow to dark tea-like color and affect its taste and smell. They come from organic materials in soil, peat, and vegetation, and can enter water through rainfall, runoff, surface water, or even deep groundwater wells. While tannins are not a health concern, they can make water look and taste unpleasant. The high-capacity cartridge is designed to fit standard slimline and Big Blue housings, making it suitable for whole-home or commercial water treatment.
