Aries (AF-10-4000-BB) 10"x4.5" Big Blue Mixed Bed Deionization (DI) Filter
Aries AF-10-4000-BB 10"x4.5" Big Blue Mixed Bed Deionization Filter
Nuclear-grade resin technology removes dissolved solids to achieve ultra-pure water for laboratory, automotive, and specialty applications
Mixed bed deionization removes what carbon and sediment filters cannot
Ion Exchange Resin
Combines anion and cation resins in a single cartridge to strip dissolved minerals, metals, and ionic contaminants from water at the molecular level
Ultra-Low TDS Output
Produces water with near-zero total dissolved solids, ideal for spot-free rinsing, battery topping, cosmetic formulation, and other purity-critical uses
Big Blue Standard Size
Fits any 10"x4.5" Big Blue housing, making it easy to integrate DI polishing into existing whole-house or point-of-use filtration systems
Lead & Heavy Metal Removal
Deionization captures lead, copper, nickel, and other dissolved metals that pass through standard carbon block or sediment filters
Fits standard 10-inch Big Blue housings
The Aries AF-10-4000-BB is designed for any Big Blue filter housing that accepts 10"x4.5" cartridges. Commonly used in Pentek, Culligan, Watts, GE, and iSpring housings with 1.5" cap threads. Best results when installed after sediment and carbon pre-filtration.
Replace when TDS readings rise
Check output regularly
Use a TDS meter to measure treated water. When output exceeds 10 ppm or doubles from baseline, the resin is exhausted and requires replacement.
300-1000 gallons
Actual capacity depends on inlet TDS and flow rate. Higher TDS source water or heavy usage will shorten resin life. Pre-filtration extends cartridge longevity.
Protect the resin bed
Always use sediment and carbon pre-filters upstream. DI resin is designed for polishing, not primary filtration, and will foul quickly without proper pre-treatment.
Laboratory Grade
Produces water quality suitable for scientific instruments, medical autoclaves, and pharmaceutical compounding
Spot-Free Rinse
Eliminates mineral deposits on car finishes, windows, and polished surfaces during final rinse applications
Battery & Industrial Use
Meets purity standards for lead-acid battery topping, cooling systems, and humidification equipment
Non-Regenerable Design
Replace when exhausted. Unlike commercial DI tanks, mixed bed cartridges are not recharged and should be disposed of properly
