How long it lasts
Usually every 6 months. The filter light is a reminder, not a water-quality sensor.
After replacing: Fit the new cartridge, then hold the filter/reset control on the fridge display until the filter indicator clears (varies by model; check the manual for the fridge).
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
