During the decoration, I have done a lot of homework in selecting the water purifier. I found that many people have been uncertain since the beginning to the end of the decoration. Most of them are difficult to choose. In fact, it is not difficult to choose a water purifier. You can become an old driver by following the following six steps, regardless of your own needs and interference information.

The first step is to look at the water quality. If the water quality is good, you can choose ultrafiltration. If the water quality is poor, you can choose reverse osmosis. I feel more confident about reverse osmosis. However, the most controversial issue is the minerals in the water, which is not bad. Everyone knows the water quality in China, because they are not used to drinking water that is harmful to your health.

The second step is population. Blind selection of large capacity belongs to the pearl sparrow, 1000g and 400g. The merchants will only tell you that the water is flowing fast, not that the cost of changing the core is high. The noise of the pump is greater. The difference in flux is the speed of water flowing, and the filtering effect is the same. It is recommended to choose according to the population of the family. Don't spend more money for a few more seconds.

The third step is to look at the budget. The filtering effect of 1000 and 5000 water purifiers is similar, but the difference in value lies in the materials and brand premium. In addition, the more expensive the machine is, the better it is, and the imported one is not better than the domestic one. Only those that are suitable for their own family situation and meet their family needs are cost-effective.

The fourth step is to look at the material. The wading parts must be food grade raw materials, with corrosion resistance and no harmful substances penetrating, so as to ensure no secondary pollution. The supporting faucet must be lead-free.

The fifth step is to look at the filter element. It is acknowledged that the RO membrane and the confluence membrane are better.

Step 6: Look at the water marks. Each machine has a Chinese water efficiency mark. According to the latest water efficiency regulations, water purifiers below Level 3 are not allowed to be sold on the market. The environmental protection of the first level water efficiency is the best。
