Berkey Fluoride Filters (PF-2™) Pack of 2

• The Berkey PF-2™ Fluoride and Arsenic Reduction Elements adsorb the following unwanted elements found in drinking water:
  • Fluoride: Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid (aka Hydrofluorosilic Acid)
  • Arsenic: V and pre-oxidized Arsenic III
  • Other residual heavy metal ions
• Made from safe, non-leaching Polypropolene #5 that is BPA-free
• Berkey PF-2™ Fluoride and Arsenic Reduction Elements are designed to be used in conjunction with the Black Berkey® Purification Elements only 
• Attach to the bottom of the Black Berkey® Purification Elements and sit in the lower chamber of the Berkey unit
• 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 PF-2 Filters
• Set of 2 Berkey PF-2™ Elements need replacement after 1000 gallons of use
• The Berkey PF-2™ Fluoride and Arsenic Reduction Elements are covered under a six month warranty

The PF-2 is for use with Black Berkey Purifiers - If you use ceramic filters, you will need the PF-4 *** PF-2 reduction elements are designed for use in conjunction with Black Berkey water purification elements to adsorb the following unwanted elements found in drinking water. Fluoride, Arsenic V and pre oxidized Arsenic III, Other residual heavy metal ions.

FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (99.75% reduction). ARSENIC: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations. REPLACEMENT: Under normal conditions it is recommended that each set of two PF-2 elements be replaced after 1,000 gallons.
