Droplets of Dew Establishment Stage One: Consists of a cotton candle made of polypropylene material that filters up to 5 microns and works to remove solid impurities such as sand, mud, and algae. Stage Two: Made of thermally activated carbon, its function is to remove dissolved gases and treat water from undesirable substances such as chlorine, taste, odor, and color. Stage Three: Made of solid carbon with 1-micron pores, its function is to remove the smallest impurities before the water enters the fourth stage. Stage Four: This is a unit known as the membrane. It contains extremely fine and narrow pores up to 0.00001 microns and relies on the property of reverse osmosis to remove salts, bacteria, and heavy metals. It starts at a 96% rejection rate, called mechanical rejection, which does not use any chemicals. Stage Five: A carbon filter made from coconut shells that works to remove any unpleasant odor or taste after the water is stored in the tank. Stage Six: Adds charges to the water as if the water was placed in earthenware pots. Stage Seven: An alkaline filter that balances the water's alkalinity (pH).
