Healthy water that can be drunk for a long time should meet the following requirements: no odor, no impurities, no chlorine, no bacteria, no viruses, no pollutants, no inorganic salts, aerobic, beneficial minerals.
Unqualified water harm to the human body, there are visible, there are invisible. Visible is usually microbial pollution hazards, may cause sudden acute disease, but people used to drinking boiled water, can kill microbial pollutants, this harm is not obvious; Invisible hazards, easier to ignore but more noteworthy. Excessive amounts of organic compounds in tap water can lead to chronic diseases. Drinking water with excessive amounts of organic compounds is no problem for one day or two days, or for six months or one year. However, organic compounds will accumulate in the human body and eventually cause harm to the body, which may be carcinogenic, teratogenic and mutagenic in severe cases.
With the increasingly prominent problem of domestic water pollution in recent years, people begin to focus more on high-quality living conditions and a healthier living environment. Water purification equipment can effectively remove pollutants, impurities, coliform viruses, heavy metals and other harmful substances in the water.
While the demand for water purification equipment is growing, consumers' requirements for water purification products are also gradually improving. The core technology used, the real water purification effect, brand trust and other factors are becoming the core of consumer concern.
At present, the common water purifier filtration technology on the market mainly includes four categories: hollow silk membrane, ceramic filter element, activated carbon particle filter, reverse osmosis filtration.
Hollow silk film: effectively reduce bacteria and macromolecular chemicals, will retain beneficial minerals for the human body. Ineffective to inorganic salts, viruses, easy to block, high cost.
Ceramic filter element: can filter large particles of pollutants (0.5-0.8um), can remove bacteria in a short time, can be reused after cleaning. The filtration speed is slow, ineffective to many inorganic compounds, unable to kill bacteria, viruses, parasites, easy to become a hotbed of germs.
Activated carbon particle filter: Reduce chlorine gas, improve taste, smell and color, reduce parasites. It is ineffective against many organic and inorganic compounds, bacteria and viruses. There is usually no filter cartridge to replace the monitor.
Reverse osmosis: Filter all substances in the water, the filtered water is called pure water, long-term drinking is harmful to human health. Reverse osmosis filtration produces a large amount of wastewater and is costly. A water filter machine for home is really recommended for the purification of your home drinking water.
How to choose a water purifier?
When purchasing, it is recommended to consider the filtration technology of water purifier first, which affects whether the filtered water produced can be drunk for a long time, meet the requirements of good health water, whether water saving and environmental protection; It is also necessary to consider its performance in professional authority certification, intelligence, safety, brand reputation and other aspects. If you meet these requirements, you can rest assured to buy.
Inferior water purifier not only does not have the function of purifying water, but will pollute the water quality. But now many inferior water purifiers are difficult to distinguish only from the appearance, because many of the filter element of the water purifier is sealed, can not judge the quality of the filter material, and the poor quality of the filter element will introduce new pollution, and even become a breeding ground for bacteria.
There are some water purifier products because of stainless steel liner chromium, nickel and other heavy metals exceed the standard, long-term drinking will cause harm to the human body.
The key to distinguish a water-related product is whether it has a health approval document issued by the health administration, which is the same for both domestic and imported water purifiers. This certificate is issued by the government for water-related products, marking their health and safety of the only authoritative document.
