The device works to become Reverse Osmosis through the American Membrane Extra PureThe device consists of (7) stages of purification and produces 280 liters / dayEquipped with a high-capacity pump of up to 25 liters / min12 liter galvanized steel tankIt works through the following stages:-1- First stage: Sediment Filter (5 microns)It purifies the water entering the device from suspended impurities, and separates fibers, sand, rust, and any of the solid impurities that are not dissolved in the water. (to be changed from 3 to 4 months depending on usage) 2- Second stage: Granular Activated Carbon Filter (2 microns)It is a carbon filter consisting of activated carbon granules that remove concentrated chlorine and chlorine involved in chemical reactions such as chloramine. (Changes from 6 to 9 months depending on usage) 3- Third stage: Carbon Block Filter (2 microns)It is a solid carbon filter that removes any additional chlorine, as well as any odors or colors that have not been completely removed in the second stage and absorbs the organic materials present in the water. This stage prepares the water to enter the most important stage in the device, which is the membrane. (Changes from 9 to 12 months depending on usage)  4- Fourth stage: Membrane Filter (0.0001 microns)At this stage, the water is pumped by a silent pump, the Booster Pump, through a semi-permeable membrane, with a permeability of (0.0001 microns), and it works by the theory of reverse osmosis, where more than 95% of the unwanted components that are usually and generally present in drinking water are separated, including pollutants. Chemicals such as salts and oxides of heavy metals (iron - manganese - lead ... etc.), as well as all fungi, bacteria and viruses. These pollutants are disposed of through the drain connection connected to the device, and then the purified water is stored under pressure in a special 12-liter tank connected to the device And high-purity water is drawn from it through a separate tap as needed. (Changes from 12 to 24 months, depending on usage)Note: the size of the bacteria is from 0.4 microns, and the size of the virus - 0.04 microns and they are completely eliminated at this stage (as the membrane permeability is 0.0001 microns). 5- The fifth stage: In Line Carbon FilterThe clear, pure water from the tank passes to an activated carbon filter to remove odors and dissolved gases and treat the taste and smell of the water just before it is used for maximum water purity. (Changes from 12-18 months depending on usage) 6- Sixth stage: calcite They are saturated granules with treated calcium that work to equalize the acidity ratio of the water. They are saturated granules with treated calcium that work to equalize the acidity ratio of the water and add a percentage of calcium to enjoy more healthy water. (Changes from 18 to 24 months depending on usage) 7- Seventh stage: Infra-Red FilterIt is the stage immediately prior to use, where the water passes over bio-ceramic granules saturated with infrared rays, as it activates and improves the level of oxygen in the blood, as it dissolves fats, chemicals and toxins from our bodies, and therefore Works on homogeneity and blood flow and has a positive impact on the general health of the body. (to be changed every 3 years depending on usage)One year warranty against manufacturing defects
