Aries (AF-20-2215-BB) 20"x4.5" Big Blue 5 Lb. KDF-85-GAC Filter
AF-20-2215-BB 20"x4.5" Big Blue KDF-85/GAC Filter
Heavy-duty specialty filter combining 5 pounds of KDF-85 media with granular activated carbon for iron, hydrogen sulfide, and chlorine removal in whole-house applications
The Aries AF-20-2215-BB addresses common well water problems with a dual-media approach: KDF-85 alloy removes iron, hydrogen sulfide, and heavy metals through redox reactions, while granular activated carbon handles chlorine, taste, and odor. This is a workhorse filter for homes dealing with rotten egg smell or rusty water.
