Berkey Fluoride and Arsenic Reduction Water Filter PF-2 (Set of 2)
Berkey Fluoride and Arsenic Reduction Water Filters PF-2 are designed for use with Black Berkey water filters to adsorb the following unwanted elements found in drinking water.
- Fluoride: Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid (aka Hydrofluorosilicic Acid)
- Arsenic: V and pre-oxidized Arsenic III
- Other residual heavy metal ions
The number of PF-2s must always correspond with the number of Black Berkey filters installed in the upper chamber. For example, 4 Black Berkey (2 sets of 2) would require 4 PF-2s (2 sets of 2), and so on.
In lieu of Black Berkey® Elements Replacement Filters, we recommend the new Phoenix Gravity New Millennium Edition.
- The PF-2 shell is made from safe, non-leaching Polypropylene #5. This BPA-free plastic is used for food containers such as ketchup and yogurt containers.
- PF-2 filters reduce the filtration flow rate by 15-20%.
- Do not boil the PF-2 filters.
*Due to state regulations, not available for sale in California or Iowa.
Replacement
Under normal conditions, we recommend replacing each set of two PF-2 filters after approximately 1,000 gallons. For instance, the Royal Berkey system is about 3.25 gallons. The PF-2 filters should be replaced after (1,000/3.25) or 307 refills.
If the system is refilled once per day, the PF-2s should be replaced after 10 months; if refilled twice daily, after about 5 months.
Actual capacity depends on the presence of competing contaminants in the source water. High levels of fluoride, arsenic, and heavy metals may reduce the capacity and efficiency of the elements.

Using the Berkey Fluoride and Arsenic Reduction Water Filter, you can significantly reduce fluoride and arsenic in your drinking water. Fluoride is deliberately added to many municipal water supplies and is becoming controversial as research shows it may have adverse effects.
Black Berkey Elements can remove various potential contaminants, including fluoride. However, these elements lose efficiency over time as fluoride is reduced. They begin to miss fluoride after extensive use. A separate fluoride reduction filter must be used to maintain long-term fluoride reduction.
The PF-2 Fluoride and Arsenic Reduction Filters are designed to work with the Black Berkey filters. The PF-2 filter reduces fluoride and arsenic ions. The combination reduces fluoride and arsenic in water by up to 97%.
PF-2 filter elements are made of BPA-free, non-leaching Polypropylene #5. They are designed to reduce the filtration flow rate by up to 20 percent.
Water fluoridation in the US began in the 1940s and has been controversial since its inception. Competing viewpoints argue whether it is a public health achievement or an unnecessary, even dangerous, contaminant.
According to a 2013 Congressional Research Service Report for Congress15, concerns around the fluoridation of water stem in part from the increase in general fluoride exposure since the Department of Health and Human Services (HHS) issued their original, recommended water fluoridation levels in 1962:
Because the use of fluoridated dental products and the consumption of food and beverages made with fluoridated water have increased since HHS recommended optimal levels for fluoridation, many people may be exposed to more fluoride than anticipated.
Consequently, questions have arisen about whether current water fluoridation practices and levels are the most appropriate means to deliver the expected beneficial effects of fluoride while avoiding adverse effects (most commonly, tooth mottling or pitting—dental fluorosis) that may result from excessive fluoride ingestion during tooth development.
Hundreds of research articles published over the past several decades have demonstrated potential harm to humans from fluoride at various levels of exposure, including levels currently deemed safe.
Fluoride is known to impact the cardiovascular, central nervous, digestive, endocrine, immune, integumentary, renal, respiratory, and skeletal systems, and fluoride exposure has been linked to Alzheimer's disease, cancer, diabetes, heart disease, infertility, and many other adverse health outcomes, including fluoride toxicity.
Most developed nations, including Japan and 97% of Western Europe, do not fluoridate their water. Comprehensive data from the World Health Organization reports no “discernible difference in tooth decay between the minority of western nations that fluoridate water and the majority that do not.”
What is the Berkey Fluoride Reduction Water Filter PF-2?
The Berkey Fluoride Reduction Water Filter PF-2 is designed primarily to reduce or adsorb the following unnecessary elements that are commonly found in our drinking water:
- Fluoride: Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid (aka Hydrofluorosilic Acid)
- Arsenic: V and pre-oxidized Arsenic III
- Other residual heavy metal ions
Berkey PF-2 Fluoride and Arsenic Reduction Elements are used in conjunction with Black Berkey Elements and offer:
- Activated alumina- A media specifically suited for fluoride reduction
- Proper contact time- Having a dedicated element allows for the proper amount of media and proper contact time
- Easy replacement—Since they are separated, Berkey PF-2 Fluoride and Arsenic Reduction Elements may be swapped out to ensure proper performance.
The Berkey Fluoride Reduction Water Filter PF-2 is made out of Polypropylene #5, which is ensured to be safe and non-leaching. Polypropylene #5, used for the Berkey Fluoride Reduction Water Filter PF-2, is BPA-free.
The Scope and Limitations of the Berkey Fluoride Reduction Water Filter
Maximum Filtration Ability
The Berkey Fluoride Reduction Water Filter is guaranteed to reduce unwanted metal elements. However, its maximum capacity for this primary responsibility is approximately 1000 gallons of water. After filtering approximately 1000 gallons of water, it is time to replace the filter.
Manually Counting Its Life Expectancy
This is one of the tricky characteristics of the Berkey Fluoride Reduction Water Filter. Yes, it says that its maximum filtration capacity is approximately 1000 gallons. But the question is, how do you know if it has reached its limit? Well, it is not as hard as it may sound. But you have to compute it manually. For you to figure out if your Berkey Fluoride Reduction Water Filter PF-2 is reaching its maximum capacity, you have to do the following:
- Always keep track of how many times you refill your water system. Each water system has its gallon capacity indicated; please note that number.
- Next, multiply that number by your water system's gallon capacity. For example, the Berkey Light system has a 2.75-gallon capacity. You refill your Berkey Light three times a week. So, that should be 3 x 2.75. The answer will be the number of total gallons you drink every week.
- Lastly, divide the answer that you have from the second step. This is to determine the number of weeks your Berkey Fluoride Reduction Water Filter PF-2 will last before replacement.
Product Compatibility
As mentioned above, the Berkey Fluoride Reduction Water Filter works only in conjunction with the Black Berkey Elements alone. All these work together to deliver the most reliable, safe, and drinkable water.
The Water’s PH Levels
Another limitation of the Berkey Fluoride Reduction Water Filter PF-2 is the pH level of your water. Testing shows that the Berkey Fluoride Reduction Water Filter PF-2 cannot efficiently reduce fluoride when your water has a pH below 5 or above 7. In short, to acquire optimum effectiveness and reliability from the Berkey Fluoride Reduction Water Filter PF-2, ensure that your drinking water’s pH level is between 5 and 7.
Taking Care of the Berkey Fluoride Reduction Water Filter
- Remove your Berkey Fluoride Reduction Water Filter from the water system and allow the filters to air-dry completely.
- Next, place them inside a sealed plastic bag. Make sure that it is sealed tightly and securely.
- Lastly, store them inside your refrigerator. But always put them farther from the freezer spot.
The Berkey PF2 Fluoride Water Filter
Water is essential for our health, but sometimes, the water we drink contains unwanted and harmful chemicals. These include fluoride and arsenic. However, the Berkey Fluoride PF2 Water Filter can reduce these components.
The Proprietary Fluoride Reduction Media, PF-2, will reduce any inorganic fluoride salts. All fluoride salts are soluble in water. So it does not matter what fluoride salts are in the water; fluoride is present as an anion, and the media will absorb fluoride ions.
This media has an unusually high surface area of more than 350 sq. m./gram of material, which allows more efficient removal of the fluoride and arsenic ions. The controlled development of the pore size distribution from 30 to 100 Angstroms enhances the high surface area, providing greater accessibility to surface-active sites via bulk diffusion.
Here is some information on what it is, what it does, precautionary measures, and how it reduces fluoride, arsenic, and other unwanted contaminating chemicals in your drinking water.
Berkey Fluoride Reduction Water Filter PF2
The Berkey PF2 Fluoride Water Filter can be augmented with the Black Berkey Water Elements to eliminate impurities such as arsenic, MTBE, fluoride, and other heavy metals.
When strung directly onto the Black Berkey Water Filters, the fluoride elements will effectively remove the hazardous impurities in your drinking water. The fluoride water filter is compatible with All Full-Size Berkey Water Filter Systems and serves as a post-filter for the Black Berkey Water Filter.
TEST RESULTS FOR BERKEY PF-2 FLUORIDE AND ARSENIC REDUCTION ELEMENTS
Independent lab testing reveals how Berkey PF-2 Fluoride and Arsenic Reduction Elements perform over time. Look at the first column for the volume tested and the last for the % fluoride reduction. It is critical to have multiple samples to determine the rate of “% “Reduction” drop-off and, by association, the element's lifespan.
Under normal contamination conditions, the media in a Berkey PF-2 Fluoride and Arsenic Reduction Elements set is estimated to reduce fluoride by up to 1,000 gallons.
Benefits and Features
- It effectively lessens water impurities like pre-oxidized arsenic III, arsenic V, fluoride, MTBE, and other heavy metal ions.
- It decreases the quantity of fluoride in your drinking water by 97%.
- It works as a post filter to the Black Berkey Water Filter.
- It works with other Berkey filters, such as the Big Berkey, Crown Berkey, Berkey Light, Royal Berkey, and Imperial Berkey.
- It is very easy to set up and use.
A Controversy about Fluoride in Drinking Water
A time-tested process was developed for the Berkey Fluoride Water Filter to lessen fluoride in your drinking water. Berkey developed this type of filter to address concerns among people who find the accumulation of fluoride in drinking water unacceptable or questionable.
Since the 1950s, fluoride has been accumulated in many municipal water supplies. This practice is now becoming viral or more contentious.
Reports, studies, and research have examined the risks of accumulating fluoride in drinking water. The sanitizing and health benefits of accumulating fluoride directly on tooth surfaces are uncertain.
The uncertainty begins with the fluoride already present in the drinking water. It only occurs when it is in contact with the teeth in diluted form for a very short period.
After the connection, the fluoride is absorbed, and the human body is subjected to the effects of fluoride-related illnesses and diseases for hours after ingestion.
Some faultfinders claim that at this stage, toothpaste containing fluoride is applied directly to the surface of each tooth. If fluoride is added to the water supply, it will be unnecessary and may be negligible.
The Berkey fluoride water filter allows you to improve your health by reducing fluoride levels in your drinking water by 95%.
Here are some water contaminants that PF-2 can effectively reduce.
- Fluoride
- Pre-oxidized Arsenic III and Arsenic V
- MTBE
- Other heavy metal ions
Replacement of PF-2
Experts recommend replacing each Berkey PF-2 Fluoride Water Filter set after approximately 1,000 gallons. For example, you have a Big Berkey system with a 2.25-gallon capacity and refill it twice daily.
You will use 4.5 gallons of water per day. However, under these conditions, the PF-2 fluoride water filter elements will last approximately 222 days (1000 gallons/4 = 222) or over 7 months.
The concrete replacement period for the PF-2 fluoride filter depends on how much water you use and the presence of competing impurities in the source water. High levels of fluoride, arsenic, and certain heavy metals may negatively affect the productivity and capacity of the PF-2 components.
PF-2’s Technical Information
Experts conducted a test at a current rate of less than 11 liters per minute per cubic foot of Berkey, with 20-30 parts per million of the ion in the liquid solution.
Results showed that <1 ppm of fluoride ion in the emission was distinctive for the filtering tool, indicating>95% reduction. Under optimal laboratory conditions, emissions of less than 50 parts per billion (ppb) were achieved, associated with a >99.75% reduction.
Arsenic
Arsenic oxide anions and arsenic cations have exceptional properties that this Berkey filter product efficiently targets.
Preventive Measures for PF2
Do not freeze, heat above 100 °C, or boil the fluoride water filter components.
Under normal conditions, PF2 containers reduce the water filtration rate of most Berkey systems by 15% to 20%.
The PF2 elements must also be primed, like the Black Berkey components.
Berkey PF2 elements can reduce the filtration stream rate by 15% to 20%.
The PF-2 elements are stress-free to set up. After setting up the Black Berkey components, attach the PF-2 elements to the thread trunks of the Black Berkey elements, leaving the wingnuts in place of the Black Berkey Elements.
Ensure to read the provided manual to correct the setup. The PF2 elements are installed at the bottom of the tank and are ready for use. Rest assured that the filter was discarded after the first full tank to eliminate any remaining manufacturing dust.

Under normal contamination conditions, the media in a set of Berkey PF-2™ Fluoride and Arsenic Reduction Elements is estimated to reduce fluoride by up to 1,000 gallons.
MORE ON COMPOSITION AND TESTING
The proprietary fluoride reduction media in the Berkey PF-2™ Fluoride and Arsenic Reduction Elements is a high-yield activated alumina formulated to reduce fluoride and arsenic from drinking water. This media has an unusually high surface area of more than 350 sq. m./gram of material, enabling more efficient reduction of fluoride and arsenic ions.
This high surface area is enhanced by a controlled development of the pore-size distribution from 30 to 100 Angstroms, providing greater accessibility to surface-active sites via bulk diffusion. Uniform particle size, low silica content, and high purity are proprietary fluoride reduction media characteristics.
Sodium fluoride (NaF), sodium fluorosilicate (Na2SiF6), and calcium fluoride- The Proprietary Fluoride Reduction Media will reduce all types of inorganic fluoride salts.
Fluorosilicic (Hydrofluorosilicic) acid (H2SiF6)- Testing was conducted for fluoride salts. Tests have not yet been conducted for fluorosilicic acid. However, the molecular size of fluorosilicic acid is much larger than that of fluoride salts, and fluorosilicic acid has two negative charges, whereas fluoride salts only have one. The “extra” negative charge makes fluorosilicic acid easier for the media to absorb than regular fluoride ions. Therefore, it is highly likely the media will perform similarly (or even better) in reducing fluorosilicic acid. Nevertheless, because NMCL has no dedicated test for fluorosilicic acid, we cannot make specific claims about its reduction.
THE BOTTOM LINE
Black Berkey Elements and the Berkey PF-2™ Fluoride and Arsenic Reduction Elements are powerful, proven, durable, and economical. Berkey systems are the top choice for everyone considering a gravity-fed system.
