Hydro-Logic Stealth/ Small Boy KDF85/ Catalytic Carbon Upgrade Filter — Single Unit

HydroLogic® KDF/Catalytic Carbon Upgrade Filters are advanced carbon block pre-filters effective in capturing water-soluble metals, chlorine, chloramines and scale. The carbon media is more porous than coco carbon providing a wider range of filtration. Replacement should be performed when inlet pressure and outlet pressure difference is greater than 10%. NOTE: Systems come standard with HydroLogic® Green Coconut Carbon Filters. The HydroLogic® KDF/Catalytic Carbon Filters are an upgrade option.
