Dual purification Dual purification through RO filter (Reverse Osmosis) + UV and UF filters that remove even dissolved impurities such as chemicals, bacteria, viruses, and salts, making water 100% pure. Device stages: Stage one (Cotton filter): Consists of a cotton candle made of polypropylene material that purifies up to 5 microns and removes solid impurities such as sand, mud, and algae. Stage two (Granular carbon filter): Made from 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 (Solid carbon filter): Made from solid carbon with 1-micron pores, its function is to remove the smallest impurities before water enters the fourth stage. Stage four (Salt filter): A unit known as a membrane containing extremely fine and narrow pores down to 0.0001 microns, relying on reverse osmosis properties to remove salts and heavy metals, starting from 96% rejection rate called mechanical rejection, which does not use any chemicals. Stage five (TDS Controller valve): Allows control of the percentage of salts passing through the source. Stage six (Ultrafiltration UF membrane): Prevents bacteria and heavy metals from entering in case the salt valve is opened. Its pore size is 0.025 microns and allows passage of minerals and beneficial salts for the body. ((It is excellent for people who wish to retain minerals such as calcium, magnesium, and salts in their water.)) Stage seven (Ultraviolet): An electric filter that focuses ultraviolet rays on water to kill viruses. Stage eight (Post-carbon filter): A carbon filter made from coconut shells that removes any taste or odor coming from the tank afterward. Its new price is 1400 SAR
