Air purifiers, water purifiers, vacuum cleaners... In order to improve the quality of life, more and more "purification" artifacts. Can these things really work? On July 17, the Jiangsu Provincial Quality Supervision Bureau issued a product quality inspection report. The reporter of the modern express newspaper learned that the water purifier failed the highest rate, and more than one-quarter of the products had problems. Some products have slow water output, water quality is not up to standard, and there is no purification effect. Even more surprising is that the more expensive the price, the better the product. Water purifiers, air purifiers and vacuum cleaners have all been found to be unqualified for products over 2,000 yuan.
The 31 batches of water purifier products in this spot check, the pass rate was 74.2%, and 8 batches were unqualified. For the water purifier, everyone is most concerned about whether there is any purification effect. Xia Yongsheng, director of the Water Purification Laboratory of Lianyungang Quality Inspection Center, said that the main problem of the spot check was on health safety and effluent quality. “The water purifier filter itself may precipitate harmful substances and may also breed bacteria during the assembly process.†He said that five batches of the products themselves were unqualified for their health and safety. In addition, there are 7 batches of products. After filtering through the filter core, the effluent water quality is not up to standard. "The main problem is the oxygen consumption, the total weight of the colonies, and the effect of purification."
In this spot check, the air purifier has a high pass rate, and 26 batches were randomly selected. Only 2 batches were unqualified, 1 noise was too large, and 1 formaldehyde purification effect was not up to standard. The vacuum cleaner sampled 55 batches and 4 batches failed. The main problem is that the noise is too large and the current may affect the performance of other appliances.
