Stages of Filtration: The first stage removes more than 5 micron particles of mechanical impurities, such as silt, sand, rust and scale, using the 5 Micron PP Sediment Filter. The second stage neutralizes chlorine, organic and organochlorine compounds, such as pesticides and dioxides, using the GAC Coconut Shell Carbon Filter. As a result, the taste, color and odor of water is improved. The 10-Micron CTO Coconut Shell Carbon filter is found in the third stage, it fine cleans mechanical impurities of more than 1 micron. Reverse osmosis follows, the pre-purified water is passed through a membrane. Purified water is fed to the next stage of filtration, pollution that has passed through the membrane is discharged into the sewage system. Post-Carbon cartridge conditions water and absorbs the gases dissolved in water, which gives the water a pleasant and natural taste.
