Aries (AF-20-3005-BB) 20"x4.5" Big Blue Iron-Lead Reduction Filter "Softener"
Aries AF-20-3005-BB Iron & Lead Reduction Filter
The Aries AF-20-3005-BB uses strong acid cation (SAC) resin to reduce soluble ferrous iron and dissolved lead from your whole-house water supply. This 20-inch by 4.5-inch Big Blue cartridge fits standard large-diameter housings and acts as a point-of-entry specialty filter for well water or municipal sources with elevated iron and lead levels.
Ion Exchange Filtration
Water Flows Through Resin Bed
Incoming water passes through densely packed strong acid cation resin beads inside the 20"x4.5" cartridge body.
Iron & Lead Ions Captured
Positively charged iron (Fe²⁺) and lead (Pb²⁺) ions are attracted to negatively charged resin sites and exchanged for sodium or hydrogen ions.
Treated Water Exits
Water with reduced iron and lead content exits the filter and continues to your home's plumbing system.
Replace cartridge when iron breakthrough occurs or flow diminishesFits Standard 20" Big Blue Housings
The Aries AF-20-3005-BB fits any standard 20-inch Big Blue filter housing with a 4.5-inch inner diameter, including models from Pentek, Culligan, GE, and Hydronix. Best used as a whole-house specialty filter after sediment pre-filtration. Not a substitute for a full water softener system; this cartridge targets iron and lead reduction specifically. Replace when iron staining reappears or when flow rate noticeably decreases.
