How long it lasts
Replace every 6 months — the appliance's filter light tells you when.
After fitting: 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 of the filter.
