Berkey 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.
• SIZE: Length 6", width 2.5" COLOR: WHITE REPLACEMENT: 1,000 gallons
