After-installation Services: - Periodic follow-up every 4 months - Salt level testing - Sterilization level testing - Ensuring automatic on/off function of the device * 2-year comprehensive warranty including electrical parts + Lifetime free service Purification Stages: - First Stage (Sediment Filter): Polypropylene material capable of filtering down to 0.0001 micron. Removes impurities, sediments, dust, and contaminants from water. - Second Stage (Granular Carbon Filter): Made from thermally activated carbon. Removes gases and treats water by eliminating undesirable substances such as chlorine, taste, and odor. - Third Stage (Solid Carbon Block Filter): Constructed from solid carbon with 1-micron pores. Removes the finest impurities before water enters the desalination stage. - Fourth Stage (Reverse Osmosis Membrane Filter): Reverse osmosis (RO) unit, known as a semi-permeable membrane, with extremely fine pores down to 0.00001 micron. Operates based on osmotic pressure to remove mineral and organic salts. Removal rate starts at 96% as a mechanical rejection standard. - Fifth Stage (Post Carbon Filter): Carbon filter made from coconut shells. Adjusts water pH and removes any unpleasant taste or odor after the water leaves the tank. - Sixth Stage: Contains volcanic rocks and volcanic sand that reduce water surface tension, help prevent bacterial and algal growth, and include calcite units that enrich the water with natural minerals essential for the body. - Seventh Stage (Alkaline pH Filter): Filter containing rocks that help increase the alkalinity (pH) of water. Device Accessories: - Fiberglass tank with a capacity of 18.75 liters - 1/4 inch chrome faucet - Chrome-made pipe connectors and adapters - 10-inch hose - Water inlet valve - Tank valve - Filter switch - Instructional catalog
