“Good life, starting from the waterâ€... As people demand higher water quality, water purifiers have gradually become the “new darling†of home. In 2016, China's water purifier sales were 20.3 billion yuan, of which offline sales were 4.05 billion yuan, an increase of 51.7%. There is a saying that "there are three fakes in ten." The market is hot and it also exposes some problems. The quality of the water purifier is not good Zhang Qiang, who lives in Chaoyang District of Beijing, was hesitant after visiting the water purification market: "The selling price of this family is only one hundred yuan, while the other one sells nearly 5,000 yuan. The appearance looks almost the same, it is really not good or bad. "On March 13, the reporter visited the market and found that there are many brands of water purifiers and the price is very different. Among them, the cheapest one is only 196 yuan, directly installed on the faucet; the most expensive one is the central intelligent water purifier, the price is nearly 10,000 yuan. In order to attract customers to buy, the business also played a healthy concept of activity, rich in oxygen ions, "beauty", "freckle", "can fight cancer" and other publicity is not uncommon. In a water purifier store, the clerk introduced to the reporter a RO water purifier with a price of 4,998 yuan, saying that "the filtration technology is the most advanced, it can remove 99% of impurities, and the water is the healthiest." The reporter suspected that the price was a bit high, and the clerk introduced a super-filter water purifier with a price of 998 yuan, and said that the filtered water is rich in minerals, which is good for the body. In addition to price confusion, the quality of water purifiers has been questioned. The General Administration of Quality Supervision, Inspection and Quarantine conducted a spot check on the water purifiers of 33 enterprises across the country and found that 40% were unqualified. Lu Jianguo, director of the China Household Electrical Appliances Research Institute's Health Appliance Analysis and Testing Center, said that since 2014, the AQSIQ has organized three national supervision and spot checks. The results show that the water purifiers pass rate does not exceed 70% in the household appliance industry. It is a lower level. Mr. Feng also told reporters that a 2800 yuan RO water purifier, after dismantling, found that the accessories are a 1.8 yuan melt-blown filter element, a 3 yuan compressed activated carbon filter, and There are two granular activated carbon filters of no more than 3.5 yuan, and a 60 yuan RO membrane. “In addition to the low end of the accessories, some merchants do not have the 'water batch' (drinking permit for sanitary safety products for drinking water). Industry lacks strong regulation Lu Jianguo believes that behind the phenomena of high price and unrelenting reporting, it has exposed several major problems in the water purifier industry. First, there are standards that are difficult to implement . At present, there are GB/T30307 national standards and QB/T4143, QB/T4144 industry standards, standards are available, but not widely adopted. Most companies always try to bypass the standard requirements, and some companies do not know the reasons and do not implement standards. Second, there is supervision and it is difficult to cover . At present, the water purifier industry is in a state of multiple dispersion. Although there are more than 4,000 domestic water purifier brands, there are only a handful of national brands. Behind the prosperity of the industry, the existence of a large number of small enterprises driven by interests has virtually increased the difficulty of supervision and law enforcement. The third is that there is technology and it is difficult to distinguish . The biggest problem with water purifiers is the poor experience. It is difficult for consumers to distinguish between good and bad by appearance and price. Despite the presence of water purification testing institutions, the number is small and the price is high. Enterprises are reluctant to test, so that some products do not meet the standard requirements and are also available for sale. Fourth, consumers are keen on the psychology of foreign brands, giving some unscrupulous merchants the opportunity to take advantage of the “foreign name†banner to make huge profits. Lu Jianguo said that it is difficult to form a management of thousands of small workshop-style enterprises by government-led supervision alone. Some enterprises have become the fish of the network, and there are problems such as exaggerated effects and false propaganda. He believes that consumer participation in market surveillance is the best way to regulate. Filter element should be replaced regularly The main function of the water purifier is to improve the water quality and remove harmful substances such as residual chlorine, heavy metals and suspended solids in the water. However, the use of unqualified water purifiers will pollute the water source. Lu Jianguo said: "Some manufacturers say that their water purifiers can remove 99% of impurities, can produce magnetized water, or have some health care functions. These statements are mostly marketing gimmicks, lack of scientific basis, consumers need to choose carefully. "The selection of qualified water purifiers, Lu Jianguo gave several suggestions. The first is to check the documents . It is necessary to see whether the dealer sales certificate (business license, organization code certificate, tax registration certificate, etc.) is complete. In addition, whether there is a sanitation license issued by the national health department for the sanitary safety of drinking water, if the seller does not say or can not get it, do not buy such a water purifier. The second is to understand the water quality . In areas with good water quality, you can purchase a filter water purifier; in areas with heavy chlorine, heavy pollution, or families with direct drinking needs, you can purchase reverse osmosis water purifiers. In general, the water purification device directly installed on the faucet uses a microfiltration membrane, and the effect is slightly weaker than ultrafiltration. The third is to look at the filter . In the high-hardness water quality in northern China and the limestone area in the south, the content of calcium and magnesium ions in water is high. The advanced filter water purifier with ion exchange resin filter should be purchased. In areas with heavy chlorine and different odors in the water, you can purchase household water purifiers with more activated carbon. The fourth is to look at the wastewater rate . It depends on whether the water purifier has a test report from a national accreditation body, whether it is marked with detailed manufacturer and water purifier wastewater rate. Similar to the water purifier, try to choose a low wastewater rate. The longer the water purifier is used, the more harmful substances the filter intercepts and its function is reduced. Lu Jianguo reminded that some consumers do not replace the filter element after installing the water purifier for a long time, which not only does not function as a clean water, but also may cause secondary pollution to the tap water. Regular manufacturers of water purifiers will be accompanied by an after-sales contact card, which will indicate how long it takes to replace the filter. Consumers should find the brand they bought after the sale and replace it regularly.
