Recently, a group of swindlers appeared near my home, tricking the elderly into doing so-called instrument therapy and drinking filtered water, with the ultimate goal of getting them to buy water purifiers. None of the domestic water purifier manufacturers can produce all the filter elements by themselves. RO membrane is used as the main core filter element. At present, the best water purifiers in the domestic market basically use imported Korean Han Shi membrane and American Dow membrane.

Many brands. 3M, Smith, Qinyuan, Angel, Midea, Rongshida, Albert, Lu Quan and Yikou ......................................................................................................................................... give more knowledge to the elderly and spend more time with their families. I hope everyone will not be deceived.
