PF-2 Reduction Elements: Fluoride-Free Water, any doubt get it out - Auckland - 094182123

PF-2™ Arsenic & Fluoride Reduction Elements – Set of 2

Can be used with the Berkey Light, the Travel Berkey, the Big Berkey,
the Royal Berkey, the Imperial Berkey and Crown Berkey

PF-2 reduction elements are designed for use in conjunction with Black Berkey® water purification elements to remove 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 3,785 litres. 
For example, the Royal Berkey® system is about 12.3 litres therefore the PF-2 filters should be replaced after 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 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.


Do not boil this element.
PF-2 elements reduce total filtration flow rate by 15-20% as they provide added water purification.


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.


The media used in the PF-2 filter elements contains high-grade activated aluminium oxide, which currently is the most efficient media available for extracting fluoride from water. Below are the results obtained when testing the PF-2 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 elements as the system is used. To give a scale for comparison purposes, test results include a US national brand toothpaste and water boiled in an aluminium pan.

• US National brand toothpaste 52.878 ppm aluminium
• Water boiled in an aluminium pan for five minutes: 2.791 ppm aluminium
• PF2 after conditioning (5 cycles): .178 ppm aluminium
• PF2 after 10 Cycles: .037 ppm aluminium
• PF2 after 20 Cycles: .029 ppm aluminium

While the above results indicate that the residual process dust adds a minute amount of aluminium to the water, the Black Berkey® purification elements reduce aluminium from the water.  The water tested naturally contained .320ppm aluminium and was filtered through a combination of the Black Berkey® and the post conditioned PF-2 filtration elements (5 cycles). The results showed a net reduction in aluminium contamination (Raw influent: .320ppm - Effluent after passing through the Black Berkey® and PF-2 elements: .232ppm).

In other words the Black Berkey® elements removed more aluminium from the water than was added by the PF-2 elements.
