How to choose a pure water filter device

We are not unfamiliar with pure water filtration devices, but what are the precautions when purchasing? What kind of filtration device is suitable for us? We should consider the following aspects: 1. Buy high-quality products. Users must recognize the importance of product quality when purchasing a water purifier. Second, choose the one with high cost performance. 1. The structure of the water purifier is different, and the water purification effect is also different. Generally speaking, the primary filter water purifier is simple in structure, mainly activated carbon, its filtering capacity is limited, and can only be used for coarse filtering, and the filtered water is heated and boiled for drinking. Most of the water purifiers with primary filtration are low-grade water purification products. 2. Multi-stage filter water purifier. This water purifier has two stages of coarse filtration and a set of fine filtration, and the fine filtration mostly uses hollow fiber water filter elements, and the filtered water can be directly consumed. Multi-stage filtration water purifiers are mid-range water purification products, each priced between 300 yuan and 500 yuan, which can be accepted by the working class and are currently used more by families. 3. The water purification effect of the reverse osmosis pure water machine is ideal. It has three-stage pre-filtration, one-stage reverse osmosis membrane precision filtration and one-stage post-filtration. The filtered water is free of bacteria, viruses, heavy metals, pesticides, organic matter, minerals, and odors. It is pure water and can be drunk without heating. 4. The water purified by the ultrafiltration membrane water purifier is good for the human body. The ultrafiltration membrane water purifier purifies a large amount of water, not only for drinking water, but also for cooking, cooking porridge, washing vegetables, washing face, bathing, etc., which solves the problem of all-round household water use. The filtered water is free of bacteria, viruses, heavy metals, pesticides, different colors and odors, and the advantage is that calcium and magnesium ions are retained in the water, which are beneficial to human body absorption. 3. Choose according to the water quality. 1. The water hardness in different regions is different. The high-hardness water in northern my country and the limestone region in the south have high calcium and magnesium ions in water, which are easy to scale. You should purchase an advanced filter water purifier with an ion exchange resin filter element. 2. For urban tap water with chlorine, heavy color and odor, and high organic content, you can choose a household water purifier with a large amount of activated carbon. Because activated carbon has a strong adsorption effect on residual chlorine, different colors and odors in water, and has obvious removal effect on organic matter. 3. For the purification of tap water with turbid water quality in urban and rural areas, household water purifiers with dual functions of coarse filtration and fine filtration should be purchased. The water is seriously polluted, and it is required to completely filter out bacteria, viruses, different colors and odors, pesticides, heavy metals and other impurities in the water. If you drink it directly without heating, you should purchase a reverse osmosis water purifier. 4. No matter what water quality can be basically solved by the ultrafiltration membrane water purifier.
