It is essential to take precautions to prevent mold growth in the Berkey Water Filter System. Mold growth can occur in the upper chamber where raw and unpurified water enters the system, as well as in the lower chamber in some cases.
To remove mold, it is recommended to remove the Black Berkey Purification elements and clean them with an abrasive pad or toothbrush. Then, re-prime the elements to flush out any old water. These purification elements are self-sterilizing, which helps prevent bacteria growth.
Additionally, to clean the stainless steel housing, wash both the upper and lower chambers with warm water and plain bleach that does not contain any artificial scents or additives. This will remove the mold and kill off any bacteria in the chambers.
To prevent mold from growing, it is recommended to change the water in the system regularly. In case you plan to leave for an extended period of time, empty the system and store the filters following the proper storage procedures.
