Replacing Your Big Blue Filter Cartridge

- Clean the housing interior and o-ring, inspect for damage, and apply food-grade silicone lubricant to the o-ring
- Insert the Aries AF-20-2212-BB cartridge into the housing, ensuring it seats properly on the center standpipe
- Hand-tighten the sump back onto the housing cap, then flush the system for 5 minutes to purge carbon fines and activate the KDF media
Housing Requirements
This cartridge fits all standard 20-inch Big Blue filter housings with 4.5-inch inner diameter, including brands like Pentek, Hydronix, Culligan, and US Water Systems. The KDF85 formulation is specifically designed for well water applications where hydrogen sulfide (rotten egg odor) and soluble iron are primary concerns.
