How often should the water filter be changed, and how do I reset the filter notification?

The water filter should be changed every 6 months, when the filter indicator light turns on, or when water output has visibly reduced. After replacing the filter, press and hold the filter button for 3 seconds to turn off the filter change notification and reset the filter change status. Note that increased water consumption may trigger the filter change notification sooner than 6 months. (Page 16, 19)
