Air purifiers, water purifiers, vacuum cleaners... In order to improve the quality of life, there are more and more 'purification' artifacts. Can these things really work? On July 17, Jiangsu Quality Supervision Bureau released a product quality spot check report. Modern Express reporter learned that the water purifier has the highest rate of failure, and more than one-quarter of the products have problems. Some products have slow water output, water quality is not up to standard, and there is no purification effect. What is more surprising is that the price is not expensive. The better the product. The water purifier, air purifier and vacuum cleaner all appear to be unqualified for more than 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. Lianyungang Quality Inspection Center Water Purification Laboratory Director Xia Yongsheng said that the main problem of this spot check is on sanitary safety and effluent quality. 'The water purifier filter itself may precipitate harmful substances, and it may also breed bacteria during the assembly process.' He said that there are 5 batches of products themselves. Safety is not qualified. In addition, there are 7 batches of products, after filtering through the filter core, the effluent water quality is not up to standard. 'Mainly oxygen consumption, the total weight of the colony has problems, it will not be able to purify.'
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.
