Installed in the lower chamber of the Berkey Water Filter, PF-2 arsenic and fluoride water filters are designed for use in conjunction with 2 Black Berkey water purification elements only to adsorb the following unwanted elements found in drinking water:
- Fluoride
- Arsenic V and pre-oxidized Arsenic III
- Other residual heavy metal ions
Note: Number of PF-2's must match the number of black berkeys working in upper chamber. ex: 4 Black Berkeys (2 sets of 2) would require 4 PF-2's (2 sets of 2), etc.
PF-2 FLUORIDE AND ARSENIC WATER FILTER TECHNICAL INFORMATION
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 (11 lpm) per
cubic foot of media.
PF-2 arsenic and fluoride water filtration 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.
REPLACEMENT:
Under normal conditions it is recommended that each set of two
PF-2 elements be replaced after 1,000 gallons
(3,785 liters) or every 2 years (whichever comes first). 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.
NOTES:
1) Do not boil this element.
2) PF-2 arsenic and fluoride water filters reduce filtration flow rate by 15-20%.
3) The media used in the PF-2
filter elements contains high-grade activated aluminum oxide, which
currently is the most efficient media available for extracting fluoride
from water. Below are the results we obtained when testing the PF-2 arsenic and fluoride water filters (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 arsenic and fluoride water filters 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.
• National brand toothpaste 52.878 ppm aluminum
• Water boiled in an aluminum pan for five minutes: 2.791 ppm aluminum
• PF2 after conditioning (5 cycles): .178 ppm aluminum
• PF2 after 10 Cycles: .037 ppm aluminum
• PF2 after 20 Cycles: .029 ppm aluminum
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. Big Berkey Water Filters homepage. For more information on the topic of fluoride, read below:

Instructions on How to Prime Your PF-2 Filters
How Activated Alumina Works:
Activated Alumina is a granulated form of aluminum oxide. It is very porous and has a tremendous surface area for the removal of contaminants. In the removal process, the water containing arsenic and/or fluoride passes over the granules in the filter with the activated alumina absorbing the arsenic and fluoride. The longer the water contact, the more the contaminants are removed.
