Premium Filtration for Your Whole House System

While standard carbon filters handle basic chlorine reduction, the CB-AF (Advanced Filtration) series takes water quality to the next level. This cartridge is the official recommended replacement for the “Stage 2” slot in BIG F PRO systems. By using cleaner, more porous coconut shell carbon, it delivers a higher adsorption capacity, effectively trapping the invisible chemical contaminants that standard filters might miss.

Targeting VOCs and Chemicals

Municipal water treatment makes water safe from bacteria, but it often leaves behind chemical by-products. This filter is specifically rated for the reduction of Volatile Organic Compounds (VOCs)—impurities including pesticides, solvents, and industrial run-off. It also completely removes the “swimming pool” smell and taste associated with chlorine, ensuring your water is fresh and pleasant to use.

Protection for Your UV Lamp

As a 5-micron block, this filter also acts as a fine sediment barrier. It captures tiny particles that passed through the first stage, polishing the water to crystal clarity. This is critical for the efficiency of your UV lamp, as clear water allows the UV light to penetrate and disinfect more effectively.
