Recently, I want to buy a three-in-one water purifier. I heard that there is a hanshill, with high filtering accuracy and backwashing. Hanshill is still quite reliable. after all, it is a German brand specializing in water purification equipment for decades. The three-in-one water purifier is their latest patented product. using hollow fiber UF membrane, not only the water quality is clean and assured, moreover, the powerful function of backwashing is clean and fast and thorough. it is completely a provincial choice. the landlord will consider it. What is the concept of three-in-one water purifier? The water purifier is nothing more than micro-filtration, ultra-filtration and reverse osmosis. The highest filtering accuracy is reverse osmosis. don't believe in the concept that merchants boast.
