Tap water qualified, but also install water purifier？You'll know after you read it

There is a saying in the movie Mermaid, "If you can't drink a glass of clean water and breathe a breath of clean air, no matter how much money you make, you will die."。

Clean water, is a helpless and often have to mention the topic。What was once a casual source of life now needs to be taken with caution。 To this end, many families have installed water purifiers to ensure the safety of drinking water for their families。However, some people believe that the tap water at home is qualified by the water treatment plant, and if the water purifier is installed again, it is a repeated investment and unnecessary consumption。

For this problem, the user who installed the water purifier and changed the filter element will know that the original clean filter element is covered with yellow sand and other pollutants after a period of use, if there is no water purifier, these visible and invisible harmful impurities will be drunk into the body。

So where do all these pollutants come from? The first is the water network。After leaving the factory, the tap water is transported or stayed for a long distance through the water supply network, and various problems will occur when it reaches the user。In particular, the water pipeline with a long life will inevitably produce aging corrosion problems after a long time of use, and the water quality yellowing, sand and rust problems in many areas are water pollution caused by aging water pipes。

This is followed by pollution caused by secondary water supply towers and water tanks。If the water tank of some high-rise communities is not cleaned for a long time, it will store a lot of pollution impurities。Long-term accumulation will lead to severe pollution of tap water, and the tap water delivered to every household will not reach the standard of direct drinking。

There is still residual chlorine, and most water plants generally use the traditional treatment process of precipitation filtration and chlorination disinfection。Chlorine is a strong oxidizing agent and is widely used in the world as a disinfectant for tap water。Residual chlorine is the amount of chlorine remaining in the water after chlorination and disinfection。According to international requirements, the safe amount of residual chlorine is the end of the pipe network (household tap) should be maintained at 0.05 mg/l water to control the growth of bacteria in the transport process, so the municipal tap water contains residual chlorine。

After the residual chlorine is heated, it produces carcinogens such as trichloromethane with organic detritus in the water。Drinking water with excess chlorine for a long time can lead to heart disease, coronary atherosclerosis, anemia, bladder cancer, liver cancer, rectal cancer, high blood pressure and allergies。

Therefore, even if it is a factory qualified tap water, it still needs a water purifier to carry out deep purification in order to be safe to drink。At this stage, there are a variety of water purifier product models on the market, the price level is different, and the quality is also uneven。So how should we choose a safe water purification product for the home？

1, to have product health license approval

The Measures for the supervision and Administration of drinking water sanitation stipulate that water-related enterprises must have a sanitation license issued by the sanitation supervision department, and have been authenticated by the technical supervision department, and meet the State's "drinking water quality standards"。If you don't get that, don't even think about buying it。 The enterprise has a sanitary license indicating that the enterprise has the qualifications, capabilities and conditions for the production of water purification equipment;Water purification products are safe and reliable, and contact parts will not cause secondary pollution。Only water purifiers with sanitary conditions are qualified products。

2, it is important to choose the right filter element

According to different purification principles and processes, water purifiers can be divided into microfiltration, ultrafiltration, nanofiltration, reverse osmosis and other types。

3, to have perfect after-sales service

Many consumers in the purchase of certain brands of water purifier products, will not be able to find maintenance service phone or maintenance service, this situation makes consumers very helpless, but also caused a waste of resources, so that many water purifiers have become a decoration。 Water purifier after-sales service is mainly focused on the replacement of the filter element, if the filter element is not replaced for a long time, it will pollute the water quality, and the water purifier will also become a "sewage device".。The choice of water purifier is to choose a perfect after-sales service system。Now, we know that installing water purifiers is not only not a duplication of investment, but a necessity。
