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.
This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.
Under normal conditions it is recommended that each set of two PF-2 elements be replaced after 1,000 gallons (3,785 liters). The Royal Berkey system is about 3.25 gallons (12.3 liters) therefore the PF-2 arsenic and fluoride water filters should be replaced after 1,000/3.25 (3,785/12.3) 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 arsenic and fluoride water filters 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.
While the above results indicate that the residual process dust adds a minute amount of aluminum to the water, the Black Berkey purification elements reduce aluminum from the water. We tested water that naturally contained .320ppm aluminum and filtered it through the combination of the Black Berkey and the post conditioned PF-2 arsenic and fluoride water filters (5 cycles). The results showed a net reduction in aluminum contamination (Raw influent: .320ppm – Effluent after passing through the Black Berkey and PF-2 arsenic and fluoride water filters: .232ppm). In other words, the Black Berkey elements removed more aluminum from the water than was added by the PF-2 arsenic and fluoride water filters
