The quantity of filterable water from a “Black Berkey” filter element: 11,350 liters with tap water and up to 4 times less with “recovered” water
Lifespan of 2 filter elements: Let's take an example, with 12 liters of daily filtration with tap water we obtain a lifespan of approximately 5 years (and 1 and a half to 5 years with recovered water depending on the quantity of impurities).
An abnormally high level of limescale can considerably reduce the lifespan of “Black Berkey” filter elements.
Average filtration cost: 0.00675 euros per liter (lifespan of the pair of “Black Berkey” filter elements of 22,700 liters).
