Aries (AF-10-3690-BB) 10"x4.5" Big Blue Activated Alumina Filter
AF-10-3690-BB 10"x4.5" Big Blue Activated Alumina Filter
High-capacity activated alumina cartridge engineered for fluoride and arsenic reduction in whole-house and point-of-entry applications
The Aries AF-10-3690-BB utilizes high-purity activated alumina to target fluoride, arsenic, and other dissolved contaminants that standard carbon and sediment filters miss. With a capacity of 6,093 grains (CaCO3) and an oversized 10"x4.5" body for maximum media fill, this double-open-end cartridge fits standard Big Blue housings and delivers reliable performance at flow rates up to 0.25 GPM.

Housing & System Compatibility
The Aries AF-10-3690-BB is designed for standard 10"x4.5" Big Blue filter housings used in whole-house, point-of-entry, and commercial water treatment systems. The double-open-end (DOE) design ensures compatibility with residential and industrial pressure housings from major manufacturers. This cartridge is ideal for well water applications, municipal water with elevated fluoride or arsenic levels, and as a polishing stage in multi-barrier filtration systems. Best results are achieved when used in conjunction with sediment pre-filtration and when water quality parameters fall within the guidelines listed above.
Aries Filter Works manufactures specialty filtration cartridges in the USA with lot traceability and FDA-approved materials for reliable, consistent performance.
