How long it lasts
Replace every 12 months (Ionmax: replace once every 12 months) — the appliance's filter light tells you when.
After fitting: 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 of the filter.
