How do I know when to change my AquaTru Classic or AquaTru Classic Smart countertop filters?

When it becomes necessary to replace a filter, the digital display panel will indicate this requirement by illuminating a specific numbered light. This light corresponds directly to the filter that needs to be replaced, providing a clear and straightforward notification to the user. Importantly, this indicator will remain lit throughout the filtering process as well as after the filtering has been completed. It serves as a persistent reminder that action is required.

The illuminated light will only turn off once the replacement of the filter or filters has been carried out. After replacing the necessary Filter, the user must then press the filter reset button to clear the notification. This step is crucial as it ensures that the system is aware of the new filter installation and can operate efficiently moving forward. Overall, this system is designed to keep users informed about the status of their filters and to facilitate timely maintenance, thereby ensuring optimal performance of the equipment.
