Due to different living habits and understanding of drinking water, opinions on water purifiers also vary from person to person. Generally divided into two types. Some people think that water purifiers are an IQ tax, while others think that water purifiers are a necessity. It is an indispensable health guardian for us modern people.
The three most important factors that affect life span are nutrition, a healthy living environment and medical care. Nutrition and medical standards aside, in terms of a healthy living environment alone, ancient people had to face the major challenge of not having a water purification system. The main sources of drinking water for ancient people were well water and river water. In ancient times without drainage systems, production and domestic sewage easily polluted river water and well water. As a result, ancient people fell ill due to unclean drinking water. The medical level and nutritional conditions at that time were relatively poor. Difference.
The tap water used by people in modern society meets the national drinking water standards when it leaves the factory. In addition, people usually cannot see any dirt in the tap water from the glass, but this does not mean how clean the tap water ultimately delivered to the home is. When tap water leaves the factory, it passes through water pipes that are winding for tens of kilometers and buried underground for decades. The water pipes are rusted and damaged and are not flushed for many years. It is almost inevitable that contaminants such as sediment, rust, bacteria, and heavy metals will be mixed into the tap water.
Polluted tap water poses a threat to human health that cannot be ignored. For example, it increases the incidence of stones, increases the burden of kidney filtration and causes kidney disease, increases the burden of liver detoxification and induces hepatitis, cirrhosis, etc. Therefore, even tap water that is qualified when leaving the factory actually contains great health risks, and the water purifier is the last line of defense to avoid this risk.
In a whole-house water purification system, the pre-filter is most easily overlooked. As the first line of filtration defense, it has the lowest price and lowest effect compared with other water purification equipment. Therefore, many people think that the pre-filter is an "IQ tax" thing, and they will be fooled if they buy it, so there is no need to install it. The pre-filter, as the name implies, is a pre-filter water purification device installed at the household end of the tap water (behind the water meter). In order for tap water to flow into the house, it must first pass through the pre-filter, so the pre-filter closes the first line of defense for the entire house's filtration system. Tap water is not pure water. Many times it contains a lot of impurities. Especially in certain areas with poor water quality, tap water will have more impurities. For example, common ones are rust, sediment, microorganisms, viruses, bacteria, metal ions, etc. Tap water with many impurities cannot be drunk directly.
