alkaline or non alkaline (basic)
Our latest generation of multi-step filter cartridges are non alkaline by default. Using this ring, you increase the pH by 1 to 1.5 points to slightly alkaline (basic water).
If you choose the alkaline combination when ordering (for the AQV 5 and 12), you will automatically receive the pH ring with it.
The contents of this ring include: tourmaline, magnesium, zeolite, magnetite and alkaline beads.
