Berkey Bb9-2 Black Purification Replacement Elements Set of 2

These Black Berkey Purification Elements work better than most commonly available gravity filter elements you would find. In tests these filters have shown to work amazingly well even with water that carries way more pathogens than would otherwise be found in regular sources of water. Black Berkey purification elements are so powerful they can remove red food coloring from water without removing the beneficial minerals your body needs. Virtually no other filtration element can duplicate this performance. This concentration of pathogens is so great that the post filtered water should be expected to contain 100 000 or more pathogens per liter (99.99% reduction - the requirement for pathogenic removal). Incredibly the purification elements removed 100%!
