Home Master CFRFGAC20-20BB Replacement Whole House Filter - High Flow 20 GPM, Radial Flow GAC, 20-inch x 4.5-inch

Engineered to fit Home Master Whole House systems and 20-inch Big Blue housings, the CFRFGAC20-20BB replaces standard carbon cartridges with a purpose-built, high-flow solution. The coconut shell activated carbon media is designed to optimize taste, aroma, and overall purification in demanding applications. The radial flow design helps maintain a robust water stream while supporting iron reduction and a minimal pressure drop, so daily use stays smooth and predictable. With this filter, you may notice water that feels crisper at the tap and smells neutral, especially when the system previously carried noticeable chlorine or chemical aromas.
