How long it lasts
Replace every 6 months — the appliance's filter light tells you when.
After fitting: Press and hold the Water Filter button for three seconds to reset the indicator (LG AU guidance across its filter pages).
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point of the filter.

Fitting it
A few minutes, no tools. Watch it done, then follow the steps.
- 1Open the fridge door and find the filter housing at the top of the fresh-food compartment; on most models a small cover flips down.
- 2Turn the old filter a quarter turn anti-clockwise and pull it straight out. A little water may drip; keep a cloth handy.
- 3Take the caps off the new filter, push it into the housing and turn it clockwise until it stops.
- 4Run 4 litres of water through the dispenser to flush the carbon, then reset the filter light (hold the filter or reset button for 3 seconds).
