How often should I replace MAXTRA+ water filter?

As filtered water consumption is increasing, as a general rule we recommend replacing your MAXTRA+ filter every 4 weeks or 150 litres of water usage. However each Australian household is unique, this timing can vary per household depending on your family size and water drinking rates of each person. 

Therefore we've developed the calculator below to help you work out exactly when you need to change your MAXTRA+ or MAXTRA+ Limescale filter to maintain optimum filtration results.
