There’s nothing to do with Cristalinn every day.
You must, from time to time, clean the Arion filter which is supplied with the Cristalinn and this as a good family pere. This cleaning takes 5 minutes.
However, there is no miracle:
The Cristalinn needs volcanic rocks and activated carbon to function.
We therefore recommend a maintenance that is a standard exchange of the blue ball, and this, every 150 m³.
Statistically, 150 m³ is an annual consumption for a family of 4 persons and, therefore, every 2 years for a couple.
