The CleanSensor™ Monitor is an easy way to see when it’s time to change your filter because it measures the amount of time the filter has been in your pitcher. Be sure to reset your CleanSensor™ Monitor every time you replace your filter.
Filter change light changes color depending on how long filter has been in use or how much water has been filtered. Filter will reach end of life at 40+ gallons or 60+ days.
The filter change light contains a non-replaceable battery. The battery will eventually stop working but the filter is still functional.
