超滤净水器推荐系列/型号:LU3A-3C、LU3B-5C、LU3-51C、LU3-62C
 
Since its establishment in 1992, Lisheng has been focusing on the research and development and production and application of ultrafiltration membrane technology, is the key drafting unit of the relevant national standards for ultrafiltration membranes, and is also one of the few enterprises in the world that can independently develop high-performance ultrafiltration membranes and achieve large-scale mass production.
 
However, Lisheng's development policy of focusing on the research and development and production of ultrafiltration technology has not changed, and reverse osmosis products have not been launched on the market. Although Lisheng said in the publicity that the ultrafiltration water purifier can meet the standard of direct drinking, and can also retain the minerals in the tap water, and use the "Shanghai World Expo Park Direct Drinking Water Equipment Supplier" to corroborate, but Shanghai's tap water quality itself is better, heavy metal pollution is small, ultrafiltration water purifier can indeed retain minerals, but at the same time can not completely remove heavy metal ions, so from the perspective of safe drinking water, ultrafiltration water still needs to be boiled before drinking safely.
 
Since the ultrafiltration membrane does not have the ability to completely remove metal ions from tap water, Lisheng's products are more suitable for areas with soft tap water quality and low heavy metal pollution. Lisheng's ultrafiltration water purifier basically follows the product strategy of "large flow and affordable price", taking LU3B-5C as an example, its effluent flow rate reaches 3L/min, which is about 1200G after conversion, and it only takes 4 seconds to fill a cup of 200ml purified water, which has little impact on the flow rate of tap water, and the strong long-lasting purification ability is also one of the highlights of Lisheng ultrafilter. Considering the price of 1680 yuan, if there is no direct drinking water demand for users, Lisheng ultrafiltration machine is a suitable choice.
 
It is worth mentioning that the internal filter element of the Lisheng water purifier has no activated carbon material, if the odor in the tap water is too large, the user needs to buy the "ultrafiltration companion" launched by the Lisheng separately, its built-in activated carbon filter element can effectively adsorb the odor molecules in the tap water, improve the taste of the filtered water, and remind again that ultrafiltration water must be boiled before it can be drunk with peace of mind.
