Specification Brand : Berkey BulletPoint1 : ENJOY GREAT-TASTING TAP WATER EVERY DAY AT HOME- The 4.5-gallon Imperial Berkey System can be used on a countertop in your kitchen or office to transform tap water into delicious drinking water that's also ideal for making your favorite beverages or cooking. BulletPoint2 : 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. BulletPoint3 : INDEPENDENT TESTING- Black Berkey Elements (the original BB9-2) are composed of a unique, proprietary blend of multiple media types backed by testing from accredited, third-party labs. Black Berkey Elements remove or dramatically reduce over 250+ typical contaminants that could be present in freshwater sources—no electricity, tools, or plumbing are required. BulletPoint4 : THE ORIGINAL BERKEY BB9-2 AND PF-2 FILTERS- Don't fall for lookalike filters that use our Berkey BB9-2 or PF-2 model number or trademarks in their titles or product descriptions to legitimize their brand as replacements or "compatible", when they are not. Black Berkey Elements are designed to work synergistically with Berkey PF-2 filters to target specific contaminants that far exceed the reduction capabilities of cheap knock-off filter brands. BulletPoint5 : ECONOMICAL, LONG-LASTING- Black Berkey Elements provide filtered water for just pennies per gallon. Each pair of Black Berkey Elements lasts for up to 6,000 gallons before replacement is recommended. Black Berkey Elements may require replacement sooner based upon the quality of influent water. We recommend replacing Berkey PF-2 Fluoride and Arsenic Reduction Elements after 1,000 gallons of use, under normal conditions.
