Is the health workshop water purifier good?

First of all, there are only two kinds of drinking water purification equipment sold in the eastern and western markets. Don't listen to other people's nonsense 1, reverse osmosis (commonly known as ro machine). 2. Simple ordinary water purifiers are also divided into many grades. Customers generally can't tell the difference between the two devices. The simple difference is that ro has electricity to purify water without electricity. 3, that is, the water quality on your side can be purified in Jiangnan, and the ro machine is recommended in Jiangbei. 4. The price of ro machine 1500-2200 is enough, which should be good. The most important thing about this product is after-sales. If the filter element is not replaced regularly, the water quality will be polluted twice. 5. Give you some brands that can be referenced, imported (3m, Dalton) and domestic (Qinyuan, Jinjiade, Midea, Rum). This product is still indispensable in our daily life. No one can be sure about the pollution of water quality, so we will try our best to avoid other troubles.
