The filter lifetime of the Xiaomi Smart Evaporative Humidifier is calculated based on the humidifier’s working time. It is recommended that you clean the filter every 1 to 2 weeks, pour out the residual water in the water tank and clean the water tank to keep the humidifier in the best condition. Under normal circumstances, it is recommended to replace the filter every 3 to 6 months. When the filter prompts that it is due or the filter needs to be replaced, you can manually reset it through the Mi Home/Xiaomi Home APP.
If your humidifier is used 24 hours a day, the Mi Home/Xiaomi Home APP will prompt that your filter lifetime is due within 1 and a half months. In this case, it is recommended that you clean the filter and water tank, or directly replace the new filter, and then manually reset it through the Mi Home/Xiaomi Home APP.
