Most of the unqualified water purifiers are filter elements
A few days ago, an announcement published on the official website of the Ministry of Health showed that a random inspection of some imported small water purifiers found that 8 enterprises, including 3M, Mitsubishi, and Panasonic, and 11 models had unqualified products. Compared with the unsatisfactory sampling of domestic water purifiers, which have mainly been concentrated on domestic brands, the large-scale incident of imported water purifier products has caused consumers who have long favored foreign brands to begin to worry.
Excessive arsenic is the main reason for failure
In the list of unqualified wading products published by the Ministry of Health, almost the most well-known "foreign brands" in the water purification industry are included, including three "Yalpu" products of 3M Company and two products of Mitsubishi Corporation. .
The main reasons for the unqualified quality of these water purification products include excessive arsenic, excessive colony count, and unacceptable organic removal rate. Among them, 7 models have arsenic excess.
A domestic water purification brand R & D staff told reporters that city tap water does not contain arsenic compounds or arsenic ions, and arsenic exceeding the standard mainly refers to "poor performance in filtering arsenic ions." According to reports, arsenic is an important pollutant in drinking water and one of the few substances that can cause cancer in drinking water.
After the Ministry of Health issued a document notifying the unqualified products, 3M Company quickly issued a statement on the official website, saying that the test failed to meet the standard because "the improper storage caused the packaging to get wet, which caused the performance of the filter element and filter head of some products to decline. There is Lanpiaoer Company.
Problems with activated carbon in water purifier filter
Gu Jiuchuan, secretary general of China's water purification industry (preparation), said that the three main reasons for the failure are the most likely problems with the activated carbon of the water purifier filter. He pointed out that due to the better water quality abroad, the removal rate standards may be lower than domestic standards.
The reporter also learned that before this, the scope of random inspection of domestic water purifiers by Chinese regulatory authorities was mainly concentrated on domestic brands. Among them, the types of activated carbon filter products found to have a high unqualified rate are mainly due to the failure of the total dissolved solids, aluminum, and arsenic index immersion test, which also makes many consumers more popular with imported water purifiers.
Three companies formally recall the problematic products
Reporters visited the market and found that substandard products have been removed from home appliance stores in Beijing and some online malls. Suning and Red Star Macalline North Fourth Ring Store have removed the unqualified products. The salesperson of the water purifier area of ​​North Taipingzhuang Store of Gome said that before the Ministry of Health notified, the Gome store did not originally sell these brands and models. The product. Jingdong Mall originally had two unqualified products on sale, and it was withdrawn immediately after receiving the notice.
At present, 3M, Lanpiaoer and Panasonic have officially announced the recall of the problematic water purifier products. As of press time, other companies have not announced the recall of the problematic products.
The reporter saw on the official website of Sirius Company that the product model HWHC-UF-CT 301 can still be ordered online, and the relevant batch of this model was detected by the Ministry of Health this time.
The Danton diatom porcelain water purifier with three unqualified indicators in this test, the problem model HIS still appears on the product recommendation page of the website.
â– Consumer guidance
Reverse osmosis water purifier is the best choice for drinking water
As the core component of the water purifier, the filter element can be generally divided into two main water purifiers, a reverse osmosis machine and an ultrafiltration machine according to its composition structure. The ultrafiltration water purifier is cheap, but the effect of removing chemical pollutants in water is poor. Chemical pollution, ultrafiltration is almost powerless, and reverse osmosis can remove various harmful impurities in water. Therefore, under normal circumstances, it is recommended to use reverse osmosis water purifier for drinking water.
Zhang Xiaojian, a professor at the Institute of Drinking Water Safety at the Department of Environmental and Engineering, Tsinghua University, said, “Improper use of household water purifiers may also cause the problem of excessive colony counts and unacceptable organic matter removal rates mentioned in the announcement.†Because the water purifier filter The adsorbent materials such as activated carbon used have a certain capacity. When the adsorbed dissolved organic substances and other harmful substances are saturated, they will no longer play a role. Therefore, the filter element should be replaced regularly according to the time recommended in the manual. The replacement cost of the filter element is about 300 yuan or more per year.
