The activated carbon (pre filter) typically needs to be replaced every 6 months
The frequency of changing the filter is dependent on the quality of the raw water, which varies in each area. Pre-filters are commonly replaced after 4-6 months. When a filter needs to be replaced, the system will notify the user in advance. Please note that in order to work optimally, the system needs to be scanned on a monthly basis.
We recommend always having at least 1 pre-filter package in stock. For more information on buying Aquablu replacements, please check our webshop here
