A filter change is recommended every 6 months.

 

Your filter can effectively filter up to 1000 liters of water. 

That will come to one filter every 6 months, if you use an average of 5 liters per day.

Water quality can also affect the lifespan of the filter, especially if using hard water (bore water) through the filter.

 

Even with low usage a filter change is adviced at least once a year.
