Berkey Single PF2 Fluoride Reduction Element
Up to 98.4% reduction in fluoride.
1 Each (Single)
The Berkey PF-2 reduction elements are designed for use in conjunction with Black Berkey Purification Elements. The PF-2 Elements screw onto the Black Berkey element thread stems and hang in the bottom tank of the Berkey Filter System. After the Black Berkey Purification Elements have filtered the water, the PF-2 Elements then perfom a second stage filtration process which is designed to absorb the following unwanted elements found in drinking water:
- 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 (98.4% reduction).
When to replace?
Under normal conditions it is recommended that each set of two Berkey PF-2 elements be replaced after 1,000 gallons/pair (3,785 liters/pair) or 2 years, whichever comes first.
