The Aqua Filter BB203PS20KDFBLP three-stage water filtration system is installed on the main cold-water supply and treats water in three successive stages. It combines a 20 μm sediment filter, granular activated carbon with KDF, and a 5 μm Carbon Block filter. The stages can be replaced independently.

The first filter traps suspended solids such as soil, sand, rust, and silt. The next two stages help reduce chlorine, volatile organic compounds, and substances that affect taste and odor, while the KDF helps reduce iron, hydrogen sulfide, and selected heavy metals. The filter housing has a metal bracket, two pressure gauges to monitor inlet and outlet pressure, and pressure-relief valves. The system is not a disinfection method and is intended exclusively for cold water.
