In the face of the overwhelming publicity of water purifiers, many people realize that there may be problems with tap water. Due to the influence of various factors, there are differences in the water quality at home. Some people questioned that after drinking tap water for so many years, there is no problem, is it necessary to install a water purifier? Is it because the businessmen exaggerate the propaganda and fool people? We uncovered the truth and found that many people got it wrong.
After drinking tap water for so many years, most people live a normal life without any impact, and there is no need to install a water purifier. This is the opinion of some people, whether it is necessary to install a water purifier is our requirement for drinking water. Slightly polluted tap water may have little effect for most people, but for some it can. Of course, there are some areas that are not simply light pollution.
1)Is it necessary to install a household water purifier?
It is necessary, because the water contains rust, sediment, impurities, colloids, suspended solids, etc., although the water needs to be boiled before drinking, there are bacteria that are resistant to high temperature, and harmful substances such as heavy metals and chlorine cannot be completely boiled. Eliminated, it may also form carcinogens. Therefore, it is necessary to install a water purifier at home, which can not only filter out impurities and bacteria in the water, but also reduce scale and stones. Moreover, the water purifier is used for a long time, and it is more practical to replace the water filter core regularly. The water from the water purifier can be used not only for drinking, but also for domestic water such as cooking, which saves worry and money.
2) what are the misunderstandings in the purchase of water purifiers?
a )The higher the number of stages, the higher the filtering accuracy
The common household water purifiers on the market are ultrafiltration and RO reverse osmosis. The filtration accuracy of the ultrafiltration membrane can effectively remove impurities, bacteria, viruses, etc. in the water. RO reverse osmosis membrane can filter out substances in water, even all natural mineral elements can be filtered out, and the filtration accuracy can reach 100 times that of ultrafiltration membrane, but even the tenth grade of ultrafiltration membrane is not as good as the third grade of RO membrane, so it is not The higher the level, the better.
b) The more expensive the price, the better the filtering effect
Some unscrupulous merchants are obviously ultrafiltration machines, but they are used to pretend to be reverse osmosis water purifiers. The price is expensive, but it cannot achieve the filtering effect of the reverse osmosis filter. So don't just look at the price, but also the material of the filter element, so that you won't be fooled.
