Fluoride is not filtered out by the BOROUX Foundation™ Black filters.
Initial tests with the BOROUX Foundation™ Black filters showed that fluoride was not effectively filtered out. Although fluoride levels were reduced, this reduction did not occur over a large number of liters. True to BOROUX’s core values of transparency, they did not extrapolate data or make false claims. Therefore, according to their strict standards, fluoride is not filtered by the BOROUX Foundation™ Black filters.
Echter… met de aanvullende BOROUX Proactive™ Fluoride filters verwijderen ze tot meer dan 99% van het fluoride in de eerste 1.000 liter. Het gepatenteerde upflow-ontwerp en de dubbellaagse nanokoolstoffiltratie van deze BOROUX Proactive™ Fluoride filters maximaliseren de filtratie. De fluoride filters, gemonteerd in duurzame roestvrijstalen behuizingen, zijn compatibel met BOROUX Foundation™ Black filters en Black Berkey filters en leveren tot meer dan 3.500 liter schoon, fluoride-gereduceerd water per paar.
