The Aqua Filter BB203PS1KDFBLG triple water filtration system is installed on the main water supply and treats water in three consecutive stages. The first filter captures sediment particles down to 1 μm, while the next two combine granular activated carbon with KDF and Carbon Block to reduce chlorine, organic compounds, and unwanted tastes and odors. KDF also helps reduce iron, hydrogen sulfide, and certain heavy metals, as well as limit bacterial growth inside the filter.

The unit features a metal bracket, two pressure gauges to monitor inlet and outlet pressure, and pressure relief valves. It is intended for cold water and is not a disinfection method. The three filter stages can be replaced independently.
