COMPATIBILITY & APPLICATIONS
Where This Filter Works
The AF-10-2212-BB fits standard 10-inch Big Blue housings and is compatible with Hydro-Logic purification systems. This filter is recommended for municipal or well water supplies where ferrous iron and hydrogen sulfide (rotten egg smell) are present. The KDF-85 media is specifically formulated for iron and hydrogen sulfide removal, making it ideal for whole-house or point-of-entry well water applications. Use this cartridge when you need dual-action treatment that addresses both dissolved metals and organics in a single stage.
💧 KDF-85 is different from KDF-55. If your primary concern is iron and sulfur smell rather than heavy metals or chlorine alone, the 85 formulation is what you need for well water treatment.
