How is the filter lifespan of the Xiaomi Smart Pet Care Air Purifier calculated?

The Xiaomi Smart Pet Care Air Purifier automatically calculates the filter lifespan based on the air quality of the environment, the purifier's operation mode, speed, and runtime. If the purifier is used in an environment with poor air quality, the filter lifespan will be consumed more quickly. If the air quality is good, the filter will last longer. Overall, the filter lifespan is approximately 6 to 12 months. If the filter's remaining lifespan is ≤10%, the purifier will notify you through the display screen and the Mi Home/Xiaomi Home APP, suggesting a replacement. It is recommended to clean the outer pre-filter of the filter once a month.

Note:
The above replacement time suggestions are based on laboratory testing, and the actual timing should be based on the real usage environment and system reminders.
