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.
- 2 AUTHENTIC REPLACEMENT BERKEY PF-2 FLUORIDE AND ARSENIC REDUCTION ELEMENTS FOR BERKEY GRAVITY-FED WATER FILTER SYSTEMS, INCLUDING: Big Berkey, Berkey Light, Crown Berkey, Imperial Berkey, Royal Berkey and Travel Berkey Systems.
- FLUORIDE AND ARSENIC REDUCTION- Berkey PF-2 Fluoride and Arsenic Reduction Elements replacement filters are designed for use in conjunction with Black Berkey Elements to adsorb fluoride, arsenic(V) and pre-oxidized arsenic(III), and other residual typical heavy metal ions.
- THE ORIGINAL "PF-2 FILTERS" BY BERKEY- Berkey is still the one and only manufacturer of authentic Berkey PF-2 filters which have been proven and tested to effectively remove fluoride when used in conjunction with authentic Black Berkey Elements. Don't fall for lookalike filters that use our Berkey PF-2 model number or trademarks in their titles or product descriptions to legitimize their brand as replacements or "compatible", when they are not.
- LONG LASTING- We recommend replacing Berkey PF-2 Fluoride and Arsenic Reduction Elements after 1,000 gallons of use, under normal conditions.
- EASY TO USE- Berkey PF-2 Fluoride and Arsenic Reduction Elements attach to the bottom of Black Berkey Elements and sit in the lower chamber of a Berkey system.
