The development of water purifier and the coming of direct drinking water era. Water purifier It has been developed for more than 20 years in China and developed countries in Europe and the United States. The development of water purifiers in China can be summarized in three stages: in the first stage, the imported brands with meters such as feiaote and EPP have been positioned at the high-end consumer groups since entering China; in the second stage, the manufacturers of water purifiers such as Quanlu, Lisheng, jingzhiquan and Qinyuan have broken through the monopoly of imported brands in water purifier technology At the beginning, the water purifier unveils its mysterious veil, and the water purifier gradually faces the public consumption; in the third stage, traditional household appliance manufacturers begin to enter the water purification industry, such as Haier, Jiuyang and other brands as representatives. They rely on their own channels in home appliances to further convey the knowledge of water purifiers to consumers. With the development of water purifier and the arrival of the era of direct drinking water, more and more families begin to use water purifier to ensure their family's drinking water health. Water purifier has entered thousands of households! In this process, most consumers encounter the same problem: how to choose water purifier?
The more filter elements in the water purifier is not the better. Some low-end water purification products have 4 or 5 filter elements at any time, but they all use simple filtering materials. In the last filtration of drinking water, the disposable filter element should be used as far as possible to avoid secondary pollution caused by improper use of water purifier.
Adsorption capacity of activated carbon - the core technology of water purifier, almost all water purifiers use activated carbon. If activated carbon is not used, the taste of the effluent will be reduced no matter how high the filtration accuracy is claimed. There are three kinds of activated carbon: granular, powdered and activated carbon rod. The first two are low-cost, but the filtration is often incomplete. The latter is a safer choice, which can achieve 100% complete filtration, and the purified water can be directly drunk. In fact, the filter element that will block is a good filter element, which also shows that the water purifier is indeed effective. It is claimed that there are four ways to replace the filter element in the market
The primary filter water purifier is simple in structure and mainly composed of activated carbon, so it can only be used for coarse filtration. The filtered water is best heated and boiled for drinking. Most of the primary filtration water purifiers belong to low-grade water purification products.
Multi stage filter water purifier. This kind of water purifier has two stages of coarse filtration and a group of fine filtration, and the hollow fiber filter core is used in the fine filtration, and the filtered water can be directly drunk. The multi-stage filter water purifier belongs to the middle grade water purification product, which is widely used in the family at present.
Ro is the most ideal water purifier. It has three stages of pre filtration, one stage reverse osmosis membrane precision filtration and one stage post filtration. The filtered water has no bacteria, viruses, heavy metals, pesticides, organic matter, minerals and peculiar smell. It is pure water and can be drunk without heating. This kind of reverse osmosis water purifier belongs to high-grade water purification products.
The ultrafiltration water purifier is composed of multi-stage pre filtration and ultrafiltration membrane, which can intercept most of the bacteria and harmful substances. It is the most ideal direct drinking water purification device with the best separation and filtration effect in the world. At the same time, it retains the mineral trace elements beneficial to human body, and then uses the advantages of KDF and activated carbon to effectively inhibit the growth of bacteria and fungi in water and remove the color and odor The filtered water can be used more safely and healthily. Moreover, the water production is relatively large, and the waste water discharge is small, so it is faster and more convenient to use in the family kitchen without waiting for a long time. This kind of water purification equipment belongs to popular consumer goods. Therefore, the author suggests that consumers can choose their own suitable products according to these other points when choosing water purifiers.
