You may notice a subtle earthy or mineral-like taste when you first use your new BOROUX Proactive™ Fluoride filters. This is completely normal and temporary.
These filters use high-quality filter media that may initially impart a mild taste. To prevent or resolve this, we recommend priming each filter for at least 10 minutes with higher water pressure before installing them. Using warm water (about 38 °C) is an important tip in this regard. In tests, this method has resolved the taste issue in 100% of cases.
For the most effective priming, use the blue silicone primer that came with the filters or the BOROUX Automatic Filter Primer Pump (electric). These help rinse the filters thoroughly and ensure that your water tastes great right from the start.
