How long it lasts
Usually every 12 months (Ionmax: replace once every 12 months). The filter light is a reminder, not a water-quality sensor.
After replacing: Hold the filter/reset button until the filter indicator clears.
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
