*7-Stage Water Purifier* Stage One (Cotton Filter): Consists of a cotton cartridge made from polypropylene that filters up to 5 microns and removes solid impurities such as sand, clay, and algae. Stage Two (Granular Carbon Filter): Made of thermally activated carbon, its function is to remove dissolved gases and treat water from undesired substances like chlorine, taste, odor, and color. Stage Three (Solid Carbon Filter): Made of solid carbon with 1-micron pores, its function is to remove the smallest impurities before water enters the fourth stage. Stage Four (Salt Filter): This unit is known as the membrane. It contains very fine and narrow pores that reach up to 0.0001 microns and relies on the principle of reverse osmosis to remove salts, bacteria, and heavy metals, starting from a 96% rejection rate called mechanical rejection, which does not use any chemicals. Stage Five (Post Carbon Filter): A carbon filter made from coconut shells that removes any unpleasant odors or tastes after the water is stored in the tank. Stage Six (Minerals): A collection of volcanic rocks that contains a calcite unit that supplies water with the minerals that the body needs. Stage Seven (Alkaline Filter): Increases alkalinity (pH): balances the acidity of the water and transforms it into healthy alkaline water. Adds natural minerals: provides water with essential minerals beneficial for the body such as calcium, magnesium, and potassium.
