The BOROUX Foundation Black filters are designed for long-term use. However, the actual service life of the filters depends on various factors, such as:
● water quality;
● the contaminants present and their concentrations;
● daily water consumption;
● the substances you specifically want to filter out.
BOROUX provides a general replacement recommendation, based on a broad range of users and water qualities. In practice, the optimal replacement interval may vary from user to user.
Based on our experience with Dutch tap water, we recommend replacing the filters after, assuming average usage and the use of tap water, maximum three years. This is a practical guideline and not a fixed replacement period.
If you use water with higher concentrations of certain contaminants (for example, water from other sources), if your water consumption is high, or if you wish to ensure maximum protection against specific substances, it is advisable to replace the filters sooner.
If you want to determine exactly when replacement is needed, only regular analysis of the filtered water will provide a definitive answer.
Please note: Test results and maximum capacities vary depending on the type of contamination. Always refer to the most up-to-date information and BOROUX test results.
