Living in Daqing, drinking water contains impurities, such as oil, which is turbid and smelly. After eating it, it will make you sick and upset your stomach. How to purify?

You'd better choose reverse osmosis water purifier. From what you said, there must be chemical pollutants in the water, and long-term drinking will have an impact on the body. Reverse osmosis filter element can effectively remove chemical pollutants and odor in water. The cost of replacing the filter element once a year is around 80 yuan (just like here), which not only solves the drinking water, but also purifies the cooking water.
