Fluoride and Arsenic Reduction Filters (Black Berkey)Berkey
PF-2 Fluoride and Arsenic reduction Filters are designed to be used in conjunction with the Black Berkey Purification Elements only. Attach to the bottom of the Black Berkey Elements and sit in the lower chamber of the Berkey unit. The number of PF-2s 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 PF-2 Filters.

Fluoride: Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid (aka Hydrofluorosilic Acid), Arsenic: V and pre-oxidized Arsenic III as well as other residual heavy metal ions.
Made from safe, non-leaching Polypropolene #5 that is BPA-free. Sold in a set of 2.
Set of 2 PF-2 Filters need replacement after 1000 gallons of use.
