On October 17, Mr. Bei, a consumer in Shanghai, reported that the Xiaomi water purifier he bought two years ago showed that the amount of water purified was as high as 16,000, yet only half of it was actually used, and the machine was no longer able to display relevant data. On the afternoon of October 18, the relevant commissioner from Xiaomi responded that the use of composite filter PPC is closely related to water temperature and water quality, and there are also certain differences in the use of machines. As for the faucet not showing data, when the composite filter PPC is about to expire, the data cannot be displayed due to the size of the faucet. The machine's app can view the TDS data.
