Water safety has attracted more and more attention from families. With the increase of technology and products, water purifier products have become the first choice for everyone. Since water quality problems in different regions are different, it is necessary to choose water purifiers in their own regions. However, there are currently more types of water purifiers on the market, which are more suitable for us? First of all, we still have to start from the latest brand on the black list.
It is important to choose a big brand on the black list of Shigao and other water purifiers.
On July 17, the Jiangsu Provincial Quality Supervision Bureau notified the results of the quality supervision and inspection of the water purifier products. The spot checks showed that Zhigao, Malata, Xin Lex, Qifang, Shihan (SAEHAN), DEKEXI Dexie, Bouygues and other clean water The product was unqualified, and the failure rate was 25.8%.
According to reports, this time a total of 31 batches of water purifiers were inspected, 23 batches were qualified, and the pass rate was 74.2%. The spot check found that the nameplate instructions of the 8 batches of products were unqualified; the results of the spot check on the health safety project showed that 5 batches The sanitary safety test of the product is turbidity, the total number of colonies, and the oxygen consumption is unqualified. The effluent water quality project reflects the water quality of the water purifier. There are 7 batches of products with oxygen consumption, and the total number of colonies is unqualified; The water purification flow rate of 2 batches of products was unqualified, and the total clean water volume of 7 batches of products was unqualified.
At present, many home appliance manufacturers have introduced water purifier products, but some manufacturers do not develop and produce water purifiers themselves. They usually use other manufacturers' products to directly label and sell them. Therefore, when we purchase water purifiers, we must first See if it is a professional water purifier, and try to choose a big brand, do not choose an unknown small brand for the sake of cheap.
Different water quality in different areas, the function of the water purifier is also different
In the opening part, the water quality in different areas is different, so when we choose the water purifier, we can look at the situation in which we meet the situation, and choose the water purifier with different functions as appropriate.
1. Limestone areas in the north and south: calcium, high magnesium content
Under normal circumstances, the hardness of water quality in the limestone areas in the north and south of China will be relatively high, mainly because of the high calcium content in the water. The water quality is easy to scale, so it should be chosen with ion exchange. The water filter of the resin filter, because the ion exchange resin filter can play a role in softening the water.
2. General urban and rural areas: various bacteria, more impurities
In general, there are problems with bacteria and impurities in the water in urban and rural areas. Therefore, we should use a water purifier or a water purification combination with a relatively strong filtration standard. For example, a pure water machine uses a reverse osmosis membrane with a filtration accuracy of 0.0001 μm. It can thoroughly filter out bacteria, viruses, odors, pesticides, heavy metals and other impurities in water. The water purified by pure water machine is pure water. It can be directly consumed without heating. However, this kind of water environment is poor. It is best to use with the front water purifier to protect the pure water machine filter and increase the service life of the pure water machine.
3. General municipal tap water: Heavier odor and more organic matter
If the water in the general municipal tap water is heavy and the organic matter content is high, it is recommended to choose a household water purifier with a large amount of activated carbon. Because the heterochromatic odor in the water is generally caused by residual chlorine in the water, The residual chlorine in the water has a strong adsorption capacity. In addition, it also has obvious removal effect on some organic substances.
From November 1, 2002, the water efficiency rating is used to view
In addition to the above methods, you can also select the appropriate water purifier product by paying attention to the water efficiency level. The new water efficiency rating standard will be implemented on November 1, 2018. Consumers only need to scan the logo by mobile phone. Two-dimensional code can understand the product information such as water consumption, and can compare the water efficiency of similar products (specification) of different brands.
It is also important to change the filter regularly.
In terms of filter elements, the service life of pp cotton filter is generally between 3-6 months. The activated carbon filter will lose the effect of disinfection and sterilization for 6 months. There are other filter elements that need to be replaced after a certain period of use. If you use it without replacing the new filter element, there may be problems with the filtered water damaging your health. At present, there are also many smart water purifiers on the market that can remind you in real time when you need to update the filter. If you are not sure if you can judge When you can change the filter, you can buy this kind of smart water purifier.
