Household water purification first stage: Orth net special precision 5um one pp filter, aperture close, uniform, large commercial water purifier, the aperture can be trapped more than 5um impurity, commercial water purification, filtration efficiency up to 99%. With flow, corrosion resistance, high pressure, low cost. To stop the rust, sediment, eggs and other large particulate matter in the water. The second stage: granular activated carbon adsorption Orth net private, commercial water purification Which is good, can be strong adsorption of organic compounds, chemical pesticides, chlorine, color and smell; silver-added technology, improve the taste while effective against bacteria growth. 9-12 months of life. Third grade: 1um one precision compression activated carbon filters, aperture close, uniform pore size can be trapped more than 1um impurities, filtration efficiency up to 99%. With flow, corrosion resistance, high pressure low cost. First level: RO reverse osmosis membrane reverse osmosis membrane pore size is only 0.0001 micron, commercial water purifier rankings, all the fine impurities in water \ soluble solids \ bacteria \ and the virus can not penetrate the reverse osmosis membrane high precision. Reverse osmosis membrane water and other impurities and contaminants separated, automatic discharge of harmful substances from the outfall, the water pressure tank into the reserve. Second stage: post-activated carbon filter rear carrier silver activated carbon filter to further remove the odor and improve taste, purify water, prevent secondary pollution, so water is more sanitary and safer. Third level: sintering activated carbon filter sintering activated carbon filter may have the effect of adsorption of color, smell, chlorine, chloroform and other harmful substances to have a long life of compression activated carbon and high dirt holding capacity of the mesh structure so that the filter has a dual function of filtering performance.
