Now various brands of water purifiers flock to us. How to choose a good water purifier is very important. There are roughly the following categories: First, it is divided into imported ones (like 3M, Aihewlett-Packard, Yikou, etc. ), domestic brands (like Angel, Qinyuan, Qinerkang, Midea, etc. ) and compilation. The second is divided into pure water machine, water purifier and water softener. So how do we choose? First of all, whether you choose a water purifier or a water purifier, professionals know that pure water is mostly used in industry, and its filtration accuracy is very, very small, so small that all substances in water can be filtered out. What will happen if we drink too much water like this? Every coin has its two sides. Both focus interviews have said that drinking pure water for a long time will reduce the comprehensive immunity of the human body and lead to calcium and zinc deficiency, because pure water removes minerals beneficial to the human body and reduces the intake of trace elements. At the same time, pure water will produce a lot of waste water, which requires electricity, only a few liters of water an hour, and a water storage tank. What about the water purifier? The filtration accuracy of water purifier is generally 0. 1- 1 micron. As we all know, the size of bacteria is generally above 0.2 micron, and after filtration, minerals beneficial to human body are retained. There is no need to produce waste water, no need for electricity, and only need to rely on water pressure to treat several liters to dozens of liters of water in no time. Secondly, we should pay attention to domestic machines. There is usually a backwashing machine. Although it is cheap, there will be secondary pollution and bacteria will still exist. Although some machines have 3-5 filter elements, they are all similar, and they all use PP cotton and granular activated carbon. There is not much technical content, and the taste of water has not been greatly improved, and it is also very troublesome to change the filter element. Some change it every few months, some change it every six months, some worry after one year ... and it takes two years, and the price of replacing the filter element is very expensive. 3M, a fortune 500 company famous for its innovation for a hundred years, has a strong core technology platform for liquid filtration and more than 90 years of experience in liquid filtration industry, and is the only liquid filtration company in the world whose business spans industries such as industry, medical care, food and beverage, drinking water, etc.
In the field of water filtration, 3M covers catering water treatment, electric water treatment and household water purification. Many internationally renowned chain restaurants, coke companies, bottled water companies and double-door refrigerator brands all adopt 3M drinking water filtration system.
You have never used 3M water purification products, but you have probably drunk 3M pure water, because 3M is the same choice as KFC, McDonald's, Coca Cola, Pepsi Cola and John. More than 90% of double-door refrigerators in the world use 3M drinking water filtration system.
Is this ok?
