Annually or after 2,000 liters (Dutch) of tap water, the multi-step filter should be replaced.
When ordering, you must choose between:
Redox multistep filter.
This filter increases the pH of the filtered water to slightly alkaline water (pH between 8.5 and 9.5). Furthermore, this filter reduces the ORP (oxidation reduction potential) giving it a strong antioxidant effect (€ 45.00).
pH neutral filter
This filter has no anti oxidant action and the water is made pH neutral (between 7.2 and 7.5 pH). (€ 41,00)
