This set of two (2) Berkey PF-2 Fluoride and Arsenic Reduction Elements are designed to be used in conjunction with the Black Berkey® Purification Elements. The Berkey PF-2 filters attach to the bottom of the Black Berkey® Purification Elements and sit in the lower chamber of the Berkey unit. The number of Berkey PF-2 Elements in the bottom chamber must match the number of Black Berkey® Purification Elements in the top chamber. For example, 4 Black Berkey® Purification Elements would require 4 Berkey PF-2 Fluoride and Arsenic Reduction Elements.
