How about ultrafiltration membrane water purifier?
Not bad. The filtration principle of ultrafiltration membrane is similar to that of RO membrane, but the filtration accuracy is not as high as that of RO membrane, so the ultrafiltration machine does not need to install a pressure pump. For city tap water, it has its own pressure and can be directly installed at the water inlet. Ultrafiltration membrane is the main medium of ultrafiltration membrane. Under the pressure of source water, water molecules usually have the pore size of ultrafiltration membrane and become clean domestic water, while pollutants are intercepted and become concentrated wastewater.

90% of the harmful substances in the source water are about 0.2 micron, so if there are many impurities in the water at home, you only need to install an ultrafiltration machine to remove most of the pollutants, which can save most of the workload for reverse osmosis pure water machine and prolong the service life of the reverse osmosis water purifier filter.

The ultrafiltration water purifier adopts the internal pressure or external pressure filtration technology of hollow fiber membrane, and the filtration aperture accuracy of the membrane reaches nanometer level, and the filtration effect is far better than that of the pre-filter and PP cotton, and even smaller water-insoluble particles such as bacteria, viruses and carbon black can be intercepted and filtered; However, it has no ability to remove organic pollution, chemical pollution, odor, pigments and other substances dissolved in water, resulting in poor taste of treated tap water.

Angel was selected as the brand of water purifier, and Angel Company was founded in 1987. 1988 developed the first water purifier; The first drinking machine was developed in 1993. Angel has been deeply involved in the field of water purification for 33 years, participated in the formulation of 14 national and industrial standards, and has 768 patents. He knows more about the water quality in China and develops water purification products that are more suitable for families in China. The appearance of long-acting reverse osmosis membrane has broken the monopoly of foreign reverse osmosis membrane technology. Products sell well in 65 countries, such as the United States and Japan, and have won the choice of 200 million people around the world.
