How often
How often should you replace a BRITA water filter?
About every 4 weeks
BRITA says MAXTRA-style cartridges last about four weeks in typical UK use. If the water tastes flat or the jug fills slowly, change it sooner.

Why replace it
The resin and carbon bed saturate. A spent cartridge still pours water, but it is no longer doing the job on the pack.
