Berkey Fluoride and Arsenic Removal Water Filter PF-2 (Set of 2)

Regular price $ 61.00

Berkey fluoride water filter PF-2 reduction elements are specially designed for use in conjunction with the 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-2's 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.

  • The PF-2 shell is made from safe, non-leaching Polypropylene #5, this is a BPA-Free plastic and is used for food containers such as ketchup bottles and yogurt containers.
  • PF-2 filters reduce filtration flow rate by 15-20%.
  • Do not boil the PF-2 filters.


Under normal conditions, we recommend that each set of two PF-2 filters be replaced 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 about one time per day, the PF-2s should be replaced after 10 months, if the system is refilled about twice per day, the PF-2s 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.

Water fluoridation in the US began in the 1940s, and has been a topic of controversy 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 now may be exposed to more fluoride than had been anticipated.

Consequently, questions have emerged as to whether current water fluoridation practices and levels offer the most appropriate ways to provide the expected beneficial effects of fluoride while avoiding adverse effects (most commonly, tooth mottling or pitting—dental fluorosis) that may result from ingestion of too much fluoride when teeth are developing.

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 as safe.

Fluoride is known to impact the cardiovascular, central nervous, digestive, endocrine, immune, integumentary, renal, respiratory, and skeletal systems, and exposure to fluoride 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 all of Japan and 97% of Western Europe, do not fluoridate their water. Comprehensive data from the World Health Organization reports that there is 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 Removal Water Filter PF-2?

The Berkey Fluoride Removal Water Filter PF-2 is designed to primarily remove or adsorb these 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 Purification 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- Being separate, Berkey PF-2 Fluoride and Arsenic Reduction Elements may be swapped out as needed to ensure proper performance

The Berkey Fluoride Removal Water Filter PF-2 is made out of Polypropolene #5 that is ensured to be safe and non-leaching. Not to mention that the  Polypropolene #5 that is used for the Berkey Fluoride Removal Water Filter PF-2 is BPA-Free

The Scope and Limitations of the Berkey Fluoride Removal Water Filter

Maximum Filtration Ability

The Berkey Fluoride Removal Water Filter is guaranteed to be able to filter and remove unwanted metal elements. However, its maximum capacity to be able to such primary responsibility is limited to approximately 1000 gallons of water. After being able to filter approximately 1000 gallons of water, it is time for replacement. 

Manually Counting its Life Expectancy

This is one of the tricky characteristic of the Berkey Fluoride Removal Water Filter. Yes, it does say that its maximum filtration capacity is up to approximately 1000 gallons. But, the question is, how do you actually know if it had reached its limit? Well, it is not as hard as it may sound. But you have to manually compute it. In order for you to figure out if your Berkey Fluoride Removal Water Filter PF-2 is reaching its maximum capacity you have to do these following tips:

  • Always keep track of how many times you are refilling you water system. Each water system has its own gallon capacity indicated. So, you should take note of that number.
  • Next, use that number and multiply on the amount of gallon capacity your water system can handle. For example, you have the Berkey Light system which has a gallon capacity of 2.75. You refill your Berkey Light three times a week. So, that should be 3 x 2.75. The answer will be the number of the total of gallons you drink every week. 
  • Lastly, divide the answer that you have on the second step. This is to determine the number of weeks your Berkey Fluoride Removal Water Filter PF-2 before replacement.

Product Compatibility

As mentioned above, the Berkey Fluoride Removal Water Filter works only hand in hand together with the Black Berkey Purification Elements alone. Another of which, is that it also works in conjunction with the Berkey PF-4 post filter elements. These are crucial factors to consider to ensure yourself the highest of quality when it comes to filtering or cleansing your drinking water. All these work cohesively to bring about the most reliable, safe and drinkable water. 

The Water's PH Levels

Another limitation of the performance of the Berkey Fluoride Removal Water Filter PF-2 is the PH levels in your water. It has been tested that the Berkey Fluoride Removal Water Filter PF-2 is not capable of removing fluoride efficiently when your water turns out to have a PH level of below 5 or above 7. In short, in order to acquire optimum effectiveness and reliability from the Berkey Fluoride Removal Water Filter PF-2, ensure that your drinking water's PH level is above 5 or below 7.

Taking Care of the Berkey Fluoride Removal Water Filter

  • Remove your Berkey Fluoride Removal Water Filter from the water system and dry the filters completely in the air. 
  • Next, is to 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 in a spot that is farther from the freezer. Which means, it should either be near the refrigerator's door or somewhere at the front portion.  


The Berkey PF2 Fluoride Water Filter

Water is very important to our health.But sometimes the water that we drink contains unwanted and harmful chemicals. Some of these are made up of components such as fluoride and arsenic. But the Berkey Fluoride PF2 Water Filter can remove these components.

The Proprietary Fluoride Reduction Media PF2 will remove any types of inorganic fluoride salts. All fluoride salts are soluble in water. So it does not matter what fluoride salts that are in the water, fluoride is present as an anion where the media will absorb fluoride ions in water.

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. This high surface area is enhanced by controlled development of the pore size distribution from 30Angstroms to 100Angstroms, providing greater accessibility to the surface active sites through bulk diffusion.  

Here is some information on what it is, what it does, precautionary measures and how it removes fluoride, arsenic and other unwanted contaminating chemicals in your drinking water.

Berkey Fluoride Removal Water Filter PF2

The Berkey PF2 Fluoride Water Filter can be augmented to the Black Berkey Water Elements to eliminate impurities like arsenic, MTBE, fluoride and other heavy metals.

When strung directly onto the Black Berkey Water Filters, the elements of the fluoride will decrease in an effective way to take control of the besieged risky impurities in your drinking water. The fluoride water filter is compatible with All Full Size Berkey Water Filter Systems and works as a post filter to the Black Berkey Water Filter.


Independent lab testing reveals how Berkey PF-2 Fluoride and Arsenic Reduction Elements perform over time. Look at the first column to see the volume tested, and the last for the % fluoride reduction. It is critical to have multiple samples in order to determine the rate of “% Reduction” drop-off, and by association, the lifespan of the element.

Under normal contamination conditions, the media in a set of Berkey PF-2 Fluoride and Arsenic Reduction Elements has been calculated to reduce fluoride for up to 1,000 gallons.

Benefits and Features

  • It effectively lessens water impurities like pre-oxidized arsenic III, arsenic V, fluoride, MTBE and other weighty 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 like 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 used and developed to the Berkey Fluoride Water Filter to lessen fluoride in your drinking water. Berkey established this kind of filter to meet the apprehensions of many people who find the practice of accumulating fluoride to drinking water unacceptable or questionable.

Since the 1950’s, fluoride has been accumulated in many municipal water supplies. This practice is now becoming viral or more contentious, to say the least.

There are some reports, research and studies about the risky effects of accumulating fluoride to drinking water. The sanitization and healthy benefits of accumulating fluoride directly to the surface of the teeth are uncertain.

The uncertainty begins with fluoride that had been already accumulated to the drinking water. It only comes when it is contacted with the teeth for a very short span of time in the diluted form.

After the connection happened, the fluoride is then absorbed and the human body is subjected to the effects of illness and other diseases of the fluoride composition for hours after ingestion.

Some faultfinders claim that in this stage, extensive fluoride toothpaste is appropriately and directly applied to the surface of each tooth, fluoride, if included in the water supply will unnecessary and quite possibly be negligible.

Berkey fluoride water filter allows you to make a decision about your health by lessening the amount of fluoride in your drinking water by 95%.

Here are some water contaminants that can be effectively removed byPF-2.

  • Fluoride
  • Pre-oxidized Arsenic III and Arsenic V
  • MTBE
  • Other heavy metal ions

Replacement of PF-2

Experts recommend that each set of Berkey PF-2 Fluoride Water Filter must be replaced after approximately 1,000 gallons. For example, You have a Big Berkey system that has a capacity of 2.25 gallons and you are refilling the system 2 times daily.

You will be using 4.5 gallons of water daily. But under these conditions, the PF-2 fluoride water filter elements will only last for approximately 222 days or 1000 gallons divided by 4 = 222 or for over 7 months.

The concrete replacement period for the PF-2 fluoride filter depends on how much water you will use and the presence of other rival impurities in the source water. High stages of fluoride, arsenic and certain heavy metals may affect negatively to the productivity and capacity of the PF-2 components.

PF2’s Technical Information

A test was performed by experts with a current rate of less than11 liters per minute per cubic feet of the Berkey purifier tool at 20-30 parts per million of the ion in the liquid solution.

Results shown that of <1 parts per million or ppm of the fluoride ion in the emission were distinctive for the filtering tool or >95% reduction. Under some optimal laboratory situations, emission concentrations of less than 50 part per billion (ppb) were eagerly accomplished which associates to a >99.75% reduction.


Arsenic oxide anions and arsenic cations have exceptional possessions that this Berkey filter product efficiently targets.


Precautionary Measures for PF2

Do not put the matter to freezing temperatures, high temperature or simmer the fluoride water filter components.

Under regular conditions, the PF2 containers lessen water filtering stream rate of most Berkey filtering systems by 15 to 20%.

The PF2 elements must also be primed just like the Black Berkey components.

Berkey PF2 elements can lessen the filtration stream rate by 15 to 20%.

The PF-2 elements are stress-free to set up and after setting up the Black Berkey components, simply attach the PF-2 elements on the thread trunks of the Black Berkey purification elements, leaving the wingnuts in place of the Black Berkey Purification Elements.

Ensure to read the provided manual for correct the setup. The PF2 elements are seated in the bottom part of the tank and it is ready to use. Rest assure that the filter had discarded the first full tank to get rid of any remaining manufacturing dust.

Fantastic product

We love our Berkey water! We live in a county with high chromium 6 levels in the water, high acidity. This has made the water taste great and clean. We even use it to cook with and our ice maker. We are all so spoiled now, even my young daughters notice a difference when we are out and can't have our Berkey filtered water. I'm so glad we bought this product a couple of years ago!!!

Awesome filters & system

We are very happy with our Berkey charcoal and fluoride filters. We recommend the filtration unit to everyone who asks about it, and most people do ask since they usually don't know what the big silver canister is that is sitting proudly in our kitchen. Lol. It really is a great system, totally worth the investment, and we always enjoy the product: crisp, clean tasting water!

The Berkey is our go to!

The Berkey was recommended by a friend when we had to replace an broken faucet of an RO unit. Hated the waste of water on that TO system. Our city uses fluoride and chloromine in our water supply. We purchase the charcoal & fluoride filters. So yes, we filter city water and use reusable bottles. The filtered water tastes even better than the very palatable city water. We just like knowing that those added chemicals are being removed. Purchased the shower filter and water bottle as well during the recent sale. Love the Berkey! Cheaper than bottled spring water!

Makes Hetch Hetchy water taste sweet again

I am astonished at how good the water tastes... like when I was a kid. Thanks!

Great quality!!

Works great and the family loves the berkey!!
