4 Black Berkey Replacement Filters & 4 PF-2 Fluoride Filters (2-2 packs of each)
These two Black Berkey Purification Elements are more powerful than any other gravity filter element currently available and fit most gravity filters, dramatically improving their ability to remove unwanted contaminants (SET OF TWO).
Black Berkey purification elements are so powerful, they can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other filtration element can duplicate this performance.
No need for expensive disposable filters. Black Berkey® purification elements are re-cleanable. When the flow rate decreases simply brush the Black Berkey® purification elements with a ScotchBrite® pad under running water, reinstall and your system is again ready to purify water. Each durable and efficient purification element will last for up to 3,000 gallons (6,000 gallons per set of two) and provide years of efficient water purification. What's more, the unique Black Berkey® purification elements are self-sterilizing.
The Black Berkey® purification element formulation has been tested by State & EPA accredited laboratories to exceed EPA & ANSI/NSF (Std. 53) protocol.
We tested the Black Berkey purification elements with more than 10,000 times the concentration of pathogens per liter than is required by standard test protocol. This concentration of pathogens is so great that the post filtered water should be expected to contain 100,000 or more pathogens per liter (99.99% reduction - the requirement for pathogenic removal). Incredibly the purification elements removed 100%. Absolutely no pathogens were cultured from the effluent or were able to be detected, even under an electron microscope, setting a new standard in water purification.
The powerful Black Berkey purification elements also remove or reduce pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, trihalomethanes, cloudiness, silt, sediment, nitrates, nitrites, heavy metals, foul tastes and odors, yet they leave in the healthful and beneficial minerals that your body needs.
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
Under normal conditions it is recommended that each set of two PF-2™ elements be replaced after 1,000 gallons The Royal Berkey® system is about 3.25 gallons therefore the PF-2™ filters should be replaced after 1,000/3.25 or 307 refills. If the system is refilled about one time per day, the PF-2™'s should be replaced after 10 months, if the system is refilled about twice per day, the PF-2™'s should be replaced about every five months). Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of Fluoride, arsenic and heavy metals may reduce the capacity and efficiency of the elements.
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.
