How often should Xiaomi Smart Pet Fountain filter be replaced?

Solution:
It is recommended to clean the filter element every time the water is changed, and replace the filter element every 30 days to ensure that pets can drink high-quality water.
Note: The turbulent logistics may cause the activated carbon to be washed on the surface of the upper cover when the filter element is in use. The activated carbon particles will not appear when the water can be replaced once, and the activated carbon will not harm the pets.
Xiaomi Smart Pet Fountain filter is different from Xiaomi Smart Pet Fountain filter only in appearance and has the same function.
