Household water purifiers are plagued with uneven quality

Bottled water can solve drinking water quality problems, cooking water? Due to concerns about water quality, many families have recently been willing to purchase domestic water purifiers. Reporters visited the Guangzhou market and found that consumers who come for consultation and even purchase have increased. Miss Chen, a brand water purifier salesman, told reporters that since the second half of this year, the number of customers who came to consult with home water purifiers has increased significantly. “And most of them are doing some homework ahead of time. Technical issues can be asked one or two, indicating that there is concern."

The quality of domestic water is concerned

Recently, an agency conducted a detailed survey of the daily water use of 100 local families (50 cities, 50 rural areas). The results showed that: In a family's total water, only 2% of drinking water is used for cooking. Related water accounts for 25%, and other domestic water accounts for 73%.

As we all know, in the daily use of water, the water that enters into the body includes not only drinking water, but also cooking water, which accounts for 27% of the total water consumption. However, the vast majority of households only noticed that drinking water with a total improvement ratio of 2% was the choice of drinking bottled water, and the total water consumption for cooking was neglected.

“Has noticed this problem.” Mr. Guangzhou’s resident Mr. Lang lives in a high-rise community in Yuexiu District. He is not confident about the quality of domestic water. “Our family lives on the 23rd floor. There is no doubt that the tank water is used. The water tank is very tangled.” He said that although the community regularly posted notices to clean the water tank, “but the degree of cleaning is rarely seen by the owners. In addition, the problem of water quality is not solved by cleaning the tank. I obviously feel that it is difficult to drink tap water. Although I usually drink bottled water, I cook it. The soup is still tap water.” He felt that using bottled water to cook soup was a bit costly, and he wondered if it was time to buy a household water purifier. “There are elderly children at home, and the quality of water should still pay more attention to health.”

There are not a few consumers who have the same ideas as Mr. Lang. Reporters visited the Guangzhou market and found that consumers who come for consultation and even purchase have increased. Miss Chen, a brand water purifier salesman, told reporters that since the second half of this year, the number of customers who came to consult with home water purifiers has increased significantly. “And most of them are doing some homework ahead of time. Technical issues can be asked one or two, indicating that there is concern."

Up to 30 items of national standard

On August 1 of this year, the two new national standards for water purification appliances were officially implemented, “Household and Similar Drinking Water Treatment Cores” and “Household and Similar Drinking Water Treatment Devices.” A senior industry insider who declined to be named frankly stated that the two new national standards are only recommended standards and are not mandatory standards. For the current mixed household water purification industry, deterrence is limited and it is difficult to achieve substantive short-term results. The role. In fact, according to incomplete statistics, there are nearly 30 countries and industry standards involving household water purifiers. But with so many standards, home water purifiers on the market cannot allow consumers to buy and use them with confidence.

Statistics show that as of 2013, China has more than 3,000 water purification equipment enterprises, annual production of more than 30 million water purification equipment, annual output value of more than 30 billion yuan, and annual growth rate of about 30% for 3 consecutive years. However, according to industry sources, due to the industry's low barriers to entry and high output, coupled with the small number of companies, fewer brands, and more groups, the quality of water purifier products is mixed, and the quality of water purifiers is mixed.

The reporter visited the market and found that the price of water purifiers in the market can vary from hundreds of yuan to over ten thousand yuan. Why are the prices so different? There are many brands who frankly say that because "the standards for brand implementation are more stringent and the costs are here, prices cannot go down." The reporter also discovered that different brands all claim to be performing the national standard, but these national standards are not the same.

It is understood that domestic water purification products originated in the United States in the early 1980s and entered China in the early 1990s. Since 1998, the former Ministry of Health has implemented an administrative examination and approval system for the production of clean water products, and has arranged annual quality supervision and inspections. This inspection is only for the quality of effluent and does not involve the indicators of electrical safety, pressure, materials, waste water, etc. of the purifying products. Over the years, various departments including the Ministry of Health, the Ministry of Environmental Protection, the Ministry of Housing and Urban-Rural Development, the Ministry of Industry and Information Technology, the General Administration of Quality Supervision, Inspection and Quarantine, and the National Standards Committee have separately formulated a number of standards concerning clean water products.

New regulations will be introduced in November

According to reports, on July 15th, of the 12 industrial standards related to home appliances approved and released by the Ministry of Industry and Information Technology, 6 were related to water purifiers, including the “Maintenance Service Specification for Water Purifiers for Household and Similar Uses,” “ Standards for installation of continuous water purifiers for household and similar purposes "Home-use and similar-use faucet-type water purifiers" "Pre-filters for household and similar uses" "Reverse osmosis water purifiers and nanofiltration water purifiers for household and similar purposes "Pressurized Pump" "Industrial Standards for Performance and Installation Services of Softeners for Household and Similar Uses." These standards will be implemented on November 1 this year.

Insiders pointed out that the production of household water purifiers is not a non-standard, but too many standards, but the classification and regulations are not detailed enough, "home water purifiers have ultrafiltration membrane, reverse osmosis membrane, nanofiltration membrane, ceramic membrane For other technologies, water purification machines for different types of technology should have special standards. At present, there are only general standards." Some experts believe that the pace of renewal of water purifiers is too slow to catch up with the rapid development of water purification technology. This is a real problem that needs to be solved. “It takes several years to establish a standard, but the membrane processing technology changes with each passing day.”
