Product Overview

PF-2 Fluoride and Arsenic Reduction Filters (Set of 4)

The PF-2 reduction elements screw onto the bottom of the Black Berkey water purification elements and work in conjunction 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 (11 lpm) 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 circumstances, a set of 2 fluoride filters should be replaced every 1000 gallons

    Safe water at last!

    Posted by Todd on 15th Jan 2013

    I purchased a Royal Berkey last year. My city adds sodium fluoride to the water. I have 4 first stage filters and 4 fluoride filters installed in my Berkey. The water that comes out of the spigot is THE BEST WATER I have drank. I had been using bottled water to avoid the fluoride and other chemicals. The Royal Berkey paid for itself in less that eight months!

    These filters do a great job of filtering out fluoride from your water! Remember to screw them on with eight turns.
