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, at 12 liters of daily filtration with tap water we obtain a duration 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 the "Black Berkey" filter element filters
Average filtration cost: 0.00675 euros per liter (lifespan of the pair of “Black Berkey” filter elements of 22,700 liters).
