Although there are many water purifiers, don't pick flowers

Which is the best home water purifier? This is a difficult problem for many people who want to buy a water purifier. Looking at the water purification market, there are a variety of water purifiers, which can be described as flowers in the mist, making people puzzled. For the purchase of water purifiers, we must not just stay on the surface factors such as product appearance, price, size, etc., but also thoroughly analyze and understand the substantive content of the water purifiers, such as "type of filter element", "high and low energy consumption" and "convenience". Below, let's take a look at what are the main concerns of purchasing an excellent water purifier.

Want to know if the water purified by the water purifier is safe and healthy? When we choose a water purifier, the water purifier manufacturer must focus on the filter element category of the water purifier. The filter element is regarded as the "heart" of the water purifier, and its category difference directly affects the quality of purified water. The categories of water purifiers on the market are mainly divided into three categories: ultrafiltration water purifiers, RO reverse osmosis water purifiers and nanofiltration water purifiers.

The first type of ultrafiltration water purifier is easy to identify. General sales staff will tell you that this water purifier can remove large particles of impurities in the water, and it has no waste water and no power consumption. In fact, the filter pore size of this type of water purifier is about 0.01 micron, which can coarsely filter the water quality and remove large particles such as sediment.
The second type of RO reverse osmosis water purifier, also called pure water purifier, has a filtering aperture of about 0.0001 microns. This type of water purifier can remove almost all substances in the water, including mineral elements that are beneficial to the human body. The purified water is pure water, and the pure water is acidic, and the pH value is often around 6, which does not comply with the national "Public Drinking Water Hygiene". Standard "(GB5749-2006) PH value of 6.5-8.5. Moreover, pure water has strong solubility, which can easily cause the loss of the original mineral elements in the body and cause demineralization of the human body. It is not suitable for long-term drinking at home, and it is also not conducive to the rapid growth and development of children. In addition, the World Health Organization (WHO) research report entitled "Health Risks of Drinking Pure Water" also pointed out that pure water does not have or lacks essential minerals. Long-term intake of such water will lead to insufficient supply of beneficial elements. Ideal drinking water.
 The third type of nanofiltration water purifier has a filtration pore size of about 0.001 microns, which is between the ultrafiltration water purifier and reverse osmosis water purifier. It can not only purify heavy metals and other substances that cannot be purified by the ultrafiltration water purifier, but also purify it. More thorough; compared with reverse osmosis pure water machine can retain mineral elements, it is healthier and lower carbon, is a new generation of water purification equipment that is both safe and healthy. Therefore, in terms of ensuring the safety and health of drinking water, nanofiltration water purifiers have won.
It is important that the water purifier can ensure the safety and health of the family's drinking water. However, it is also important to pay attention to the energy consumption of the water purifier. Do not make the home a "big water and power consumer" because of the wrong selection of the water purifier. The energy consumption of the water purifier is closely related to its filtration principle. RO reverse osmosis water purifier, filtration pore size is about 0.0001 microns, and membrane separation technology using pressure difference requires pressure, power, small flow, large amount of wastewater generated, and low water yield; while nanofiltration water purifier, filtration The pore size is about 0.001 microns, and the filtration accuracy is between ultrafiltration and reverse osmosis. The operating pressure is low, the power consumption is small, and the waste water is small. Compared with RO reverse osmosis water purifiers, the water production rate is higher.
