Filter replacement
Annual filter set: every 9–12 months
Consists of the sediment, pre-carbon and alkaline/post-carbon filters. This interval may be longer or shorter depending on how heavily the device is used.
Membrane filter: every 3–4 years
The membrane filter, which serves as the main filter, is replaced on average every 3–4 years depending on frequency of use, and is considered separately from the annual filter set.
The light on the tap
If the light on the tap is blue, your filters and water are healthy; if it is red, it is time to replace the filters.
Filters classed as consumables are not covered by the warranty. Warranty terms
