Model KS838 1st Filter - Ceramic Provide effective treatment to reduce harmful bacteria such as typhoid, bilharzia & amoebas and chemical contaminates, remove rust, sediment and suspended solids, chlorine taste, unpleasant odor. 2nd Filter - Carbon Block + GAC Efficient in removing pollutants such as residual chlorine, unpleasant odor, organic compounds, colours, heavy metals (e.g. copper, lead, mercury & etc), Trihalomethanes (THMS) and other chemicals by absorption. 3rd Filter - Carbon Block + Alkaline Stone Removing heavy metals, harmful chemicals and organic materials. It also made with superior materials to ensure that water is filtered pure and cleaner. 4th Filter - Alkaline Stone & Resin Softener Various natural mineral which are beneficial to our health and Resin softener can slight trace of heavy metal, chemical and softening the water and demineralization where the strong acid functionally is impacted through a process of solution. 5th Bio - Ceramic & Super Tourmaline Mineral Ceramic Which will break water into smaller molecule cluster, improve body metabolism & increase body resistant. At the same time transform water into mild alkaline water, minimizing water odour, increasing dissolved oxygen content in the water for our body need. 6th - Activated Carbon & Antioxidant Mineral Removing organic material and resistance and anti-Bacteria from water and adjust s water to optimum mild alkaline level. Antioxidant Mineral can abundance of negative ions for reducing oxidation at human body with further small water molecule clusters and thus is more easily absorbed into our body.
