1. First of all, check the professional certification of water purification equipment, mainly to see that domestic drinking water systems have passed the test of the Ministry of Health of the People's Republic of China and received the "China Water-related Product Certification", and the certification issued by NSF, a third-party non-profit organization with the authority of the United States, which is a joint venture and imported brand of the United States.
2. It is recommended to use the prefilter system when purchasing. The prefilter system is used as a coarse filter to remove the impurities and rust of large particles, protect the subsequent filter element and extend the service life of the system.
3. At present, there are harmful metal ions such as rust, residual chlorine, sporangium, lead, etc. in water resources, so when purchasing, look at the product description and choose products according to your priorities, such as children or infants at home. In addition to selecting high-quality milk powder, the water for washing milk powder is also particularly important. Barreled water is easily contaminated by bacteria twice, and the lead and organic pollutants in water cannot be removed by boiling tap water, At this time, select products that can remove harmful metal ions such as lead in water.
4. Check the flow rate and water treatment capacity of the product. If the flow rate is too small, it is not convenient to use.
5. Check how long the subsequent filter element will be used and whether it will be blocked. The good filter element is the one that will be blocked. When the filter element is blocked, the water will become smaller.
6. The water purifier can only filter out the harmful impurities and return the water to the natural and pollution-free state. The water is pure, and drink more water, which can naturally discharge the toxins in the body and reach a healthy state. Some shanzhai factories refer to water purifiers as functional water, energy water, anti-cancer water and anti-aging water, which has no scientific basis at all.
7. Other copycat water purifier manufacturers design the water purifier into seven or even ten filter elements, which is purely speculation and misleading consumers. Generally speaking, five filter elements of water purifier are sufficient. The more filter elements, the better. Five filter elements are enough for the water purifiers of real big brand manufacturers! According to the local water quality, the specific requirements, needs and consumption of users, there are corresponding products to meet the needs of consumers!
8. Finally, we must pay attention to perfect after-sales service when purchasing water purification equipment. Don't buy the products of the copycat factory. The after-sales service doesn't know where to look for them. They spend a lot of money and don't say it. They also add to the traffic jam.
