How often do I change the Berkey Black filter elements?

If you use two Black Berkey filter elements you should change them after 6000 gallons. This equals to 2400 days, that is six and a half years.
If you use four elements, change is recommended after 12,000 gallons, that is twelve years.

(Based on EPA's daily water consumption per day including water in meals).
