Results of \u0026lt; 1ppm of the fluoride ion in the effluent were typical for the media (\u0026gt;95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (\u0026gt;99.75% reduction).\u003cbr \/\u003e\u003cbr \/\u003e ARSENIC: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.\u003cbr \/\u003e\u003cbr \/\u003e REPLACEMENT: 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\u003csup\u003e®\u003c\/sup\u003e system is about 3.25 gallons (12.3 liters) therefore the PF-2 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\u003csup\u003e\u003c\/sup\u003e's should be replaced after 10 months, if the system is refilled about twice per day, the PF-2\u003csup\u003e\u003c\/sup\u003e'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.\u003cbr \/\u003e\u003cbr \/\u003e NOTES:\u003cbr \/\u003e\u003col\u003e\n\u003cli\u003eDo not boil this element.\u003c\/li\u003e\n\u003cli\u003ePF-2\u003csup\u003e\u003c\/sup\u003e elements reduce filtration flow rate by 15-20%. \u003c\/li\u003e\n\u003cli\u003eOur original tests were done using gravity alone to purge the PF-2\u003csup\u003e\u003c\/sup\u003e elements. Since then, we have added a step by using purging buttons which are much more efficient at removing any residual process dust from the PF-2\u003csup\u003e\u003c\/sup\u003e media. The test does not distinguish between activated alumina (Al2O3) and Aluminum (Al). So we had to use the total count of aluminum and activated alumina in our tests.\u003c\/li\u003e\n\u003cli\u003eThe media used in the PF-2\u003csup\u003e\u003c\/sup\u003e filter elements contains high-grade activated alumina (Al2O3), which currently is the most efficient media available for extracting fluoride from water. Activated alumina is inert. Below are the results we obtained when testing the PF-2\u003csup\u003e\u003c\/sup\u003e elements (the water was not pre-filtered through the Black Berkey® elements). The reduction over time is due to additional residual process dust being washed free from the PF-2\u003csup\u003e\u003c\/sup\u003e elements as the system is used. To give a scale for comparison purposes we include test results from a national brand toothpaste and water boiled in an aluminum pan.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cul\u003e\n\u003cli\u003eNational brand toothpaste 52.878 ppm aluminum\u003c\/li\u003e\n\u003cli\u003eWater boiled in an aluminum pan for five minutes: 2.791 ppm aluminum\u003c\/li\u003e\n\u003cli\u003ePF2\u003csup\u003e\u003c\/sup\u003e after conditioning (5 cycles): .178 ppm aluminum\u003c\/li\u003e\n\u003cli\u003ePF2\u003csup\u003e\u003c\/sup\u003e after 10 Cycles: .037 ppm aluminum\u003c\/li\u003e\n\u003cli\u003ePF2\u003csup\u003e\u003c\/sup\u003e after 20 Cycles: .029 ppm aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\nWhile the above results indicate that the residual process dust adds a minute amount of activated alumina 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\u003csup\u003e®\u003c\/sup\u003e and the post conditioned PF-2 filtration elements (5 cycles). The results showed a net reduction in aluminum contamination (Raw influent: .320ppm - Effluent after passing through the Black Berkey\u003csup\u003e®\u003c\/sup\u003e and PF-2 elements: .232ppm). Again, the standard tests cannot distinguish between aluminum (Al) and activated alumina (Al2O3), which is inert. Nevertheless, the tests showed a net reduction by the Black Berkey\u003csup\u003e®\u003c\/sup\u003e element in the combination of naturally occurring aluminum plus any residual activated alumina (Al2O3)process dust from the PF-2 elements.\u003cbr \/\u003e\n\u003cdiv align=\"center\"\u003e\u003cspan style=\"font-weight: bold;\"\u003eNot yet available in Iowa \u003c\/span\u003e\n\u003cdiv align=\"center\"\u003e\u003ca href=\"http:\/\/www.berkeywater.com\/FAQs\/10p_California_Lead.html\" title=\"Not currently available in California\" target=\"_blank\"\u003eNot currently available in California\u003c\/a\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"New Millennium Concepts (Berkey Systems)","offers":[{"title":"Default","offer_id":712189379,"sku":"Berkey-PF-2","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/1281\/products\/pf-2.jpeg?v=1402351576","url":"https:\/\/survival-center.myshopify.com\/products\/berkey-pf-2-fluoride-and-arsenic-reduction-elements","provider":"Survival Center Development","version":"1.0","type":"link"}
