PF-2 Fluoride and Arsenic Water Filters (2) - Fits Black Berkey Filters Only

How Berkey PF-2 Fluoride and Arsenic Filters Work

The PF-2 Berkey filters effectively adsorb fluoride (Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid) and arsenic (Arsenic V and pre-oxidized Arsenic III), along with other residual heavy metal ions. This translates to cleaner, safer drinking water for you and your family.

Berkey developed these filters to specifically address concerns about fluoride intentionally added to municipal water supplies and the prevalence of arsenic in certain areas. If you're worried about these contaminants, PF-2 is the tailored solution you need for your Berkey system.

Fluoride Reduction provided by Berkey PF-2 Fluoride Filters

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.
• Sodium fluoride, sodium fluorosilicate, and fluorosilicic acid (aka hydrofluorosilicic acid) all dissociate (breakdown) to fluoride, sodium, and silicate ions once added to water.
• This PF-2 media filters any type of inorganic fluoride salt ions that are added to the water.

Arsenic Reduction provided by Berkey PF-2 Arsenic Filters

This Berkey arsenic filters uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations. If you are concerned about exposure to arsenic and arsenic toxicity, these reduction filters will remove this toxic contaminant and render your drinking water safe for you and your family to consume.

Drinking Water Controversy – Contaminants in Your Drinking Water

In regions with deliberately added fluoride or high levels of arsenic, PF-2 filters become a necessity. Concerned about fluoride in your drinking water?

Adding it to water is intended to prevent tooth decay by strengthening enamel. However, excessive exposure and ingestion may lead to fluorosis, manifesting in tooth discoloration and other potential body health issues.

As for arsenic, it is a naturally occurring contaminant that is found in drinking water supplies all around the world, including South East Asia and large parts of the US.

PF-2 filters are purposefully designed to address these concerns by reducing the amount of fluoride in your drinking water. With proven efficiency in fluoride and arsenic reduction, they stand as your dedicated guardians for water purity.

Replacement Schedule for Berkey Arsenic and Fluoride Filters

Under normal conditions, it is recommended that each set of two PF-2 filters should be replaced after 1,000 gallons of water (3,785 liters) or 1 year, whichever comes first. For example, 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.

Berkey Fluoride Filter Technology: 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 adsorbing the arsenic and fluoride. The longer the water contact, the more the contaminants are removed.

THE PF-2 REDUCTION ELEMENTS WITH BERKEY WATER FILTER SYSTEMS USAGE NOTES

• Do not boil this element.
• PF-2 arsenic and fluoride water filters reduce the filtration flow rate by 15-20%.
• The media used in the PF-2 Black Berkey filter elements contains high-grade activated aluminum oxide, which currently is the most efficient media available for extracting fluoride from water. Ideal water filtration conditions: 5-7 PH. 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 of 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.

Note: The number of PF-2 reduction elements must match the number of Black Berkeys installed in the upper chamber. For example, if 4 Black Berkeys (2 sets of 2) are installed in the upper chamber, you would need to install  4 PF-2 arsenic and fluoride reduction elements (2 sets of 2) in the lower chamber, etc. Adding fluoride filters to the lower chamber will reduce the volume in the lower chamber by approximately 0.5 gallons per set of two Berkey PF-2 filter elements. 

Note: The PF-2 shell is made from safe, non-leaching food-grade Polypropylene #5, which is BPA-Free and is used for food items such as ketchup bottles and yogurt containers.
