Black Berkey® Purification Elements are more powerful than any other gravity filter element currently available. The micro-pores within the cleanable Black Berkey® purification elements are so small that pathogenic bacteria are simply not able to pass through them.
Save money on disposable filters because the Black Berkey® purification elements are cleanable. When the flow rate decreases, simply brush the Black Berkey® purification elements with a ScotchBrite® pad under running water and reinstall. Each durable and efficient purification element will last for up to 3,000 gallons (6,000 gallons per set of two) and provide years of efficient water purification.
Comes in a set of two.
