On the 17th, the Jiangsu Provincial Quality Supervision Bureau notified the results of the quality supervision and inspection of the water purifier products. The spot check showed that the water purifier products such as Chigo, Malata, Xin Leikes, Qifang, Shihan (SAEHAN), DEKEXI Dexie, Bouygues, etc. Unqualified, the failure rate reached 25.8%.
The water purifier should be set in the obvious position
A total of 31 batches of water purifiers were randomly selected, and 23 batches were qualified. The pass rate was 74.2%. The spot check found that the nameplate instructions of the 8 batches of products were unqualified. According to the requirements, the water purifier should be set in the obvious position, clearly marked. Product name, trademark, specification model, manufacturer information, water flow and total water quantity, operating environment, rated working pressure and maximum working pressure, product number or production date, health permit approval number, implementation standard number, etc. The reverse osmosis water purifier should also indicate the rated voltage, frequency, rated power, type of protection against electric shock, etc. The quality supervision department recommends that consumers check the product description and appearance when purchasing, and clarify the product related information. The water purifier produced by the formal enterprise The logo is complete, the assembly is rigorous, and the surface feels smooth.
Part of the water purifier water quality is not good
The health safety project reflects the indicator of the amount of toxic and hazardous substances dissolved in the water purifier during use. The spot check shows that the turbidity, the total number of colonies, and the oxygen consumption of the five batches of products are unqualified. The effluent quality project reflects the water purifier. The quality of the purified water, there are 7 batches of oxygen consumption, the total number of colonies is unqualified.
There are 2 batches of products with unqualified water flow, and 7 batches of products have unqualified total water. The water flow rate refers to the water production rate, which is the water production per unit time under the specified operating conditions. The total water quantity refers to the total water production. Is the cumulative water production when any effluent is regenerated or replaced under the specified operating conditions, when the effluent quality meets the requirements and the purified water flow is not less than the nominal purified water flow. Among them, one of the productions produced by Zhangzhou Wanlida Life Electric Co., Ltd. The nominal water purifier of the water purifier is 1.5L/min, and the measured value is only 0.69L/min, which is less than half of the nominal value.
Combine water quality purchase products, pay attention to water efficiency rating
Consumers can choose different types of water purifiers for water hardness in different regions. High hardness water in the north and limestone in the south, calcium in water, high content of magnesium ions, easy to scale, should choose advanced with ion exchange resin filter Filter the water purifier; filter out most of the water, choose the pure water machine using reverse osmosis technology; remove suspended solids, heavy metals and other impurities but retain some mineral elements, you can choose other types of water purifier.
Pay attention to the water efficiency rating when purchasing. The new water efficiency rating standard will be implemented on November 1, 2018. Consumers can scan the QR code by mobile phone to know the product information such as water consumption, and compare different brands. Similar products (specification) Water efficiency. In addition, the water purifier filter needs to be cleaned or replaced regularly. It should be understood that the replacement time of each filter element of the water purifier, the price, the way to obtain the filter element and the replacement method.
