Thousands of water purifier products from nearly a hundred manufacturers have prices ranging from more than one hundred yuan to tens of thousands of yuan. Which of them are standard products? Why can't dozens of existing standards in the water purifier industry work?
From August 1 this year, two new national standards for water purifiers were formally implemented. However, the reporter found that the response of these two new national standards in the industry has been very flat in the past month and a half. When consumers buy water purifier products, they are still "listening to sales staff." People in the industry pointed out that there are too many "standards" of water purifiers and they are not targeted. In the final analysis, they lack effective mandatory national standards.
Two non-mandatory national standards issued
Since August 1, "General Requirements for Household and Similar Use Water Purification Devices" and "General Requirements for Inner Cores for Drinking Water Purification of Domestic and Similar Uses" have been officially implemented. The former national standard perfects the electrical performance standards of water purifiers, and the specific content includes the total water purification capacity, functional efficiency, noise, etc. of the water purifier; the latter national standard is directed to the inner core of the water purifier.
The person in charge of Qinyuan Group Co., Ltd., an enterprise involved in the development of the above standards, stated that the above standards stipulated the appearance, sanitation, safety, performance, electrical safety, noise, and service life of drinking water treatment equipment, and reflected the drinking water. Professionalism of the processing unit.
Consumers do not know the new national standard
For the past few days, the reporter visited various major supermarkets in the city, but found that both consumers and dealers have a low awareness of these two new national standards.
Last weekend, in the water purifier area of a home appliance store near Xicun subway station, except for a publicity board placed in the Qinyuan counter, it showed that two new national standards have been implemented since August 1; other brands have not seen relevant information. An e-commerce website (Jingdong Mall), just searching for household water purifiers, has 1,546 products. A staff member of a shop told reporters that the company has not yet notified the implementation of the new national standard and did not hear relevant information when communicating with peers.
Can the water purifier be freckle?
During the visit, the reporter also found that the effectiveness of the publicity slogan that has been exposed many times has continued unabated. In addition to the "active carbon", "microfiltration", "ultrafiltration", "reverse osmosis" and other technical concepts frequently appearing in the publicity of water purifier manufacturers, there are also manufacturers mainly promoting "ionized water", "mineralized water", Water concepts such as "small molecule cluster water", and some other manufacturers focus on functions such as "beauty", "freckle removal", and "anti-cancer".
Misunderstanding the filter element is not the better
The filter element is the core component of the water purifier. So what reference standards or data should I look for when purchasing a filter element? The reporter conducted a random survey of the citizens in the stores and supermarkets, and over 80% of them said they were unclear. "I don't know how to judge, just listen to the sales staff introduction." Consumers said.
Mr. Li spent 4,000 yuan to buy a water purifier in a shopping mall last month. When he bought it, he listened to the introduction of the sales staff. "Only the sales staff said that the inner core is divided into seven types. This is a better one, but as for No matter how good it is. "
The reporter learned that the current internal piping design of water purifiers on the market are very similar. They are made of PP cotton, granular charcoal, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon. They are usually 4 or 5 The stages are composed of end to end. Consumers tend to choose products with a five-stage filter when buying.
"The effect of five or six filter elements made of ordinary materials is not as good as that of a high-performance filter element." A dealer said that in fact, more filter elements are not necessarily a good thing. As long as there are precision filters for household water purifiers, The three processes of activated carbon and ultrafiltration membrane can basically meet the needs of the public.
Too many root standards lack mandatory standards
The reporter learned that the water purifier market is not without standards, but there are too many related standards, and there are no mandatory national standards.
In terms of the water quality that the citizens care about, the reporter learned that the existing water purification equipment clearly identified the quality of the incoming water as municipal tap water, but for the quality of the effluent, the standards followed were inconsistent, and some were in line with the "sanitary safety of drinking water quality processors And functional evaluation specifications-General Water Quality Processors; some meet the requirements of the "Sanitary Safety and Functional Evaluation Standards of Drinking Water Quality Processors-reverse osmosis treatment device" requirements; some only marked as direct drinking water; more Or skip this item directly.
According to incomplete statistics from reporters, there are currently nearly 20 standards related to water purification appliances. Most of these standards are recommended. There is neither a ¡°uniform standard¡± nor a requirement that manufacturers must implement it. There are fewer standards related to the production process. What's more, these standards are introduced by different authorities. There is no unified authority, and there is no unified supervision.
Key manufacturing-related standards need to be perfected
According to the "China Water Treatment Products Consumer Research Report" released by the China Household Electrical Appliances Association, the water purification equipment market size has reached 4.28 million units in 2013 and has maintained a compound annual growth rate of 45% for two consecutive years. On the one hand, there is strong demand, and on the other hand, the market is still in a state of chaos.
A person in charge of a water purifier company in Zhongshan City told reporters that the existing standards are not sound enough, especially those related to the manufacturing industry still need to be strengthened. "Household water purifiers are terminal water purifiers. The technical, development, performance, and quality standards of these products are what manufacturers should improve as soon as possible."
After-sales service quality average pass rate 40%
The reporter found from the China Quality Mileage complaint led by the General Administration of Quality Supervision, Inspection and Quarantine that there were 107 complaints about water purifiers since 2008. The complaints covered many problems such as quality defects, false propaganda by manufacturers, and incomplete after-sales service. The average qualified rate of after-sales service quality in the water purifier industry is only 40%.
Tips for changing the filter element in 3 ~ 6 months
People in the industry remind consumers that when buying a water purifier, they should first choose the appropriate specifications according to the size of the household water consumption. Secondly, the appropriate water quality processor should be selected according to the regional water quality conditions, so as to choose branded products. It is worth noting that the filter element, which is the core of the water purifier, needs to be replaced regularly. Basically, it needs to be replaced every 3 to 6 months, so as to avoid the use of too long time, which may cause bacterial growth and affect the life.
Filter material effect comparison
PP cotton: It can filter rust and sediment with large particles. The filtered water cannot be directly drunk.
Activated carbon: it can absorb the residual chlorine and organic matter in the water, and the filtered water should not be drunk directly.
ABS ceramic membrane: can filter bacteria, rust, sediment, residual chlorine, macromolecular organic matter, etc., the filtered water can be drunk directly.
Ultrafiltration membrane: can filter bacteria, rust, sediment, residual chlorine, macromolecular organic matter, etc., retain minerals and metal ions, can filter out mineral water.
Reverse osmosis membrane: It can retain substances larger than 0.0001 microns, and it is a precise membrane separation product. It can filter minerals and heavy metal ions to obtain pure water.
