Some people say that household water purifiers are IQ taxes. What is the reason?

Using a water purifier is not an IQ tax. Undoubtedly, the water quality in different areas of China is different. Tap water itself will not leave the factory until it meets the drinking water standard. It should be noted that tap water is piped from the waterworks to your faucet. We don't know what will happen to the water quality during this distance. If your home is high-rise, tap water will also enter the high-rise water tank, which is likely to encounter secondary pollution. At this time, you will find that the water from the faucet is turbid or smelly. Some people read the relevant reports on water quality testing and found that water quality can be tested with TDS pen. Under normal circumstances, TDS is around 50, indicating that the tap water quality is not bad. If it is lower than 50, it already meets the standard of direct drinking water. But in fact, tap water in the north will contain residual chlorine more or less, and trace elements such as magnesium and zinc can be detected in tap water in most areas. Even if the tap water is boiled, there will be white sediment. If consumers drink it directly, it will affect their health for a long time, and the most common phenomenon will lead to diseases such as "kidney calculi" and "gallstones".

The filter element is the key to the water purifier. Many brands of water purifiers attach great importance to the design and packaging of filter elements. Especially seeing the unique filter element design and integrated filter element, it seems that its filtering effect is better. When you think that the filtering effect of these uniquely designed filter elements has been replaced, then you fall into the sales pit. The unique design of the filter element of the water purifier will not improve the filtering effect, but will only increase the replacement cost of the filter element. The filter element of the water purifier needs to be replaced regularly. If the cost is too high, the later cost will be higher. If you don't want to spend too much money to replace the filter element, should you choose these composite filter or choose a unique filter element when buying a water purifier? General filter elements can also have the same filtering effect, and the replacement cost is much lower!

Chlorine is usually used in the process of purifying tap water. After the tap water is connected, there is always an odor. To put it bluntly, there is residual chlorine in the water. Because the national tap water pressure is 28 meters, the water supply of high-rise buildings with more than 6 floors needs extra pressure. At present, there are reservoirs on the roofs of high-rise buildings in order to supply water to high-rise buildings under pressure. If this reservoir is not cleaned and disinfected in time, it will also cause bacteria to breed, so there will be secondary pollution. Therefore, for the safety of drinking water, the tap water at home must be equipped with water purification equipment. There are many types of water purification equipment on the market.
