How many litres of water can pass through a britta maxtra filter before i should replace it?

Question

These filters are pretty expensive and so far ive been replacing every month but i only fill the jug once a day, occasionally twice. I have a feeling I'm throwing them out without getting the most out of them. I'm

living in the northeast od england where i think the water is pretty clear anyway.

cheers

Answer 1

This Brita site suggests every two months if you just use a jug a day
