Description
The Aries 10″ Fluoride Reduction Filter (AF-10-3690) is a specialty water filter cartridge designed to reduce fluoride levels in drinking water using advanced activated alumina media. Engineered with ResinTech® SIR-900 synthetic aluminum oxide, this cartridge helps lower fluoride — whether naturally occurring or added — and can also assist with other contaminants through its high-quality adsorption media.
Ideal for point-of-use applications where fluoride removal is a priority, the AF-10-3690 fits standard 10″ housings and is a reliable choice for homeowners seeking cleaner, safer drinking water.
