What brand of water purifier is better? The key technology of the front water purifier is in the filter screen, and the core components are in this piece, just like the chip of the electronic equipment. Directly related to the quality of the filter. Lydsey's filtration and purification technology is the leading one in the industry. many key projects use lydsey's technology, such as sediment and water flow dam in the Three Gorges Reservoir area and the second phase of Xiaolangdi Water Transfer and sand purification project. The water purifier is mainly divided into ultra-filtration water purifier, activated carbon water purifier and reverse osmosis water purifier (Ro machine ). ■ The ultra-filtration water purifier simply filters out sediment, colloid and bacteria, cannot filter out scale, heavy metals and chemical pollutants, and cannot improve the taste. the external pressure type cannot be washed and discharged, and the internal pressure type can be washed and discharged, the advantages are: no electricity,
Is the filtering accuracy 50 microns or is the filtering accuracy 90 microns good? The filtering accuracy of 50 microns is higher than 90 microns, and it is cleaner after 50 microns filtration.
