Mineralization cartridge. - The reverse osmosis filter removes 96-99% of pollutants, chemicals, dissolved solids, organic and inorganic substances from water. The mineralizing cartridge replenishes the purified water with minerals. The cartridge contains natural minerals that are crushed accordingly and dissolve in water upon interaction. In this way, additional minerals are formed in the water, which remained on the osmosis membrane during water purification. Suitable for most reverse osmosis systems on the market. Water is enriched with mineral elements such as: calcium, magnesium, potassium, sodium. The amount of minerals in mineralized water is similar to the amount of minerals in bottled mineral water.
