Many water filters on the market may claim to be a water purifier, but do not meet the performance specifications required for this classification. In order to be classified as a water purifier, a water treatment device must remove at least 99.9999% of pathogenic bacteria and reduce viruses by 99.99%.

The Berkey filters can be classified as water purifiers because they remove 99.9999999% of pathogenic bacteria and 99.999% of viruses, which greatly exceeds the standard. The filter formulation of Berkey systems (Black Berkey Purification Element) has been tested by State and EPA accredited laboratories to exceed NSF/ANSI Standard 53.

Does Berkey water filter remove fluoride?

Yes, the Black Berkey Purification Elements can initially reduce Fluoride to greater than 99.9%.
However, the efficiency of removing Fluoride begins to lose after a few hundred gallons. In order to reduce fluoride effectively, you will still need to use additional post filters that work in conjunction with the Black Berkey Filters in your system, which is called the Berkey PF-2 Elements.  A set of Berkey PF-2 elements can remove Fluoride for up to 1,000 gallons.  

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

Envirotek Laboratories, Inc., New Jersey

The results confirm that Berkey Water Filter can remove chloramines, pharmaceuticals, pesticides, heavy metals and other bad element in the water.

Bisphenol-A which is a common endocrine disruptor found in PET plastic bottles were removed to greater than 99.9% when bottled water was poured out into the Berkey.

Chloramine which is now the substitute of most refilling station to chlorine for water disinfection was also removed to greater than 99.9%.

Pharmaceuticals are now a big concern in the water supply that affects the health of people, but after the testing Berkey removed greater than 99.5% of it in the water.

Moreover, due to oil spills that happened around the world, our water has become contaminated with petroleum.  

Petroleum Contaminants (Gasoline, Diesel, Crude Oil, Kerosene, Mineral Spirits, Refined Oil) were removed to greater than 99.9%. Not only oil spills affect the water, also the Pesticides. The result after the testing was, these pesticides were also removed to greater than 99.9%.

Heavy metals were removed to greater than 99.1% after it was poured into the Berkey.

Coliform and e-Coli were also removed to over 99.9% after the testing.


Environmental Toxicology Laboratory, LA

Another laboratory conduced series of tests for Berkey Water Filter. Result shows that the filters are setting a new standard for gravity fed water filtration and purification system.

Additional new potential contaminates that show significant reduction of 95% or greater in Nitrites, MBAs or Methylene Blue Active Substances, and Arsenic

It is very remarkable that in all testing conducted on Berkey Water Filters, reduction occurred in excess of the reporting limit for each test which means that reduction levels were achieved in every case. Not only that it was achieved, it exceeds the testing limitation of the laboratory.

Analytical Services, Inc. (ASI)

A microbiological testing, research and consulting also tested Berkey Water Filters. The objective of the testing for Berkey Water Filter was to establish preliminary data regarding the efficacy of viral removal or inactivation from clean water.

After a series of testing, Berkey Water Filter showed a great result that again exceeded the expectation of the laboratory. The results of the leaching control samples suggests that no active antimicrobial agent is leaching into the treated water. Under the test conditions, the Berkey Water Filter exceeded the minimum log reduction requirements specified for all three types of microorganisms

The three laboratories that tested the effectiveness of Berkey Water Filter showed significant results to prove that Berkey Water Filters can purify water, not just filtering water.

The results were purely positive and has exceeded the expectations of each laboratories.

The Need for Water Filter

Because of the unstoppable water pollution, water is not safe for drinking anymore.  Water filters removes contaminants, chemicals, toxics, bacteria and other bad elements in water.

So with this function, water filters does not undergo one testing only. It passes through series of tests if it can remove all the bad elements in water. All water filters in the world that are approved to be sold in public should undergo the correct process. 


Water Contamination Symptoms

Water, natural in all types and forms, is not impervious to anything that alters its benefits. Exposed to pollutants and chemicals alike, fresh and groundwater systems are vulnerable and can be causes of different water-borne conditions.

Clean water is generally clear. Once you put it in glass, you can see the bottom without squinting. In the same sense, contaminated water is turbid in nature.

Water that is cloudy and becomes clear once it stands for a minute or two indicates that there is faulty water and filter systems. Water high in salt and calcium particles has crystals or scales present on them.

These types of water contamination are found to be greatly present among municipal water supply and wells. Water that is not clear indicates that there is presence of sediments like clay, sand or silt.

Greenish discoloration may indicate high acid content and rust shows iron content. In lieu with this, bluish discoloration indicates copper corrosion. Copper and lead are heavy metals that pose health risk once ingested in high amounts. 

Water contamination distinguished by taste varies greatly. Salty water indicates high amounts of sodium content. Chemically contaminated water tastes strongly of chemicals.

High alkalinity in water tastes like soap and detergent while acidic water leaves a temporary metallic taste in the mouth. Moreover, it can also taste like metal if iron is present in the water.

Chlorine-tasting water is a common complaint among households with a water supply coming from the municipality. Chlorine is widely used to disinfect water systems and is relatively safe in low doses.

But if ingested in high amounts, this could lead to conditions like eye and nose sensitivity. It also leads to dry skin and hair. Moreover, when chlorine is paired with organic matter, it can cause cancer of the colon, urinary bladder and rectum. 

Chlorine is typically used to clean water, and this poses great risks for a person’s health once consumed in the body. If the water smells dank and musty, it indicates rotting plant matter (this may be applicable for water that comes from private wells), in the same sense, water that smells like washing detergent indicate leaking septic tanks.

In addition to, water that smells like oil or gasoline indicates that these elements are present in drinking water. Relatively, if water smells fishy and musty, bacteria may be present in water. 

Chlorine-tested drinking water may be absent of bacteria and viruses, protozoa may then be present since growth is relatively high if chlorine content is high in water.

While these symptoms of water contamination may be distinguished by our senses, highly threatening water pollutants will not be detected without having the water tested. Therefore to ensure quality drinking water, it is important to use Berkey Water Filters.


 The Chemicals Found in Drinking Water

Chemicals are present in our daily lives and are one of the main causes of pollution. Since pollution is present in the air, it also is present in land and water.

From the thinnest air in the surface of the planet to the deepest trenches of the oceans, waste materials made by men can be found. Sometimes chemical wastes are also found in water, most especially in our drinking water.

By the time it goes to the public water system, it immediately gets treated with chemicals that were primarily added to remove sediments and clear the turbidity in water.

In an industry where water is the main source of business, they have to make sure that certain processes have to be made first in order for drinking water to be safe and potable before it reaches the public to be consumed.

Some water industries use filters while some use chemicals as a reagent to remove impurities naturally present in water. These chemicals are called flocculating agents that works as a coagulant and aids in filtering water. These coagulants not only filter large particles but also microscopic substances found in drinking water.


What are the chemicals found in drinking water?

Though large particles were being filtered from the lakes, springs and stored in dams then goes to the public water system to be treated, still smaller particles and microorganism remains such as, the phytoplankton which is a natural flora of water and is sometimes not visible to the naked eyes, also smaller substances of mud and sand sometimes get through the poor filtering equipments used, bacteria, protozoan, and viruses can also leak through the water filters.

By the time water reaches the storage container, chlorine is added and is dissolved to kill bacteria, protozoan and viruses. However some of these microorganisms can’t be killed by using chlorine and thus should go through purification, though not potable and safe to drink and with this treatment alone, water is then dispensed for the community to be used.

 Since water is most abundant in the ecosystem, some industries use water as a source of income and made into some kind of business. Nowadays, water coming from the water lines going directly to our home, isn’t potable at all.

So, what some water industries do is that they sell potable water for consumers and use chemical reagents to purify drinking water, but the big question lurking behind is, “Is it safe to drink?”

Chemical, by the term itself, is already toxic and when taken by the body in large amount can cause toxicity and grave diseases. Also called as flocculating agents, these chemicals can be used as a reagent that helps by clumping together the microscopic substances or particles found in water to be easily removed or filtered out.

This is a list of some chemicals that are used as reagents in drinking water.

  • Aluminum Sulphate – also called as Alum, is a coagulant that purifies drinking water and is also used to manufacture paper.
  • Liquid Chlorine – a derivative from both salt and sodium, a reagent that kills microorganisms such as bacteria, viruses, parasites and protozoan that does a unique reaction when combined with water by giving off heat or by igniting.
  • Calcium hydroxide – commonly known as slaked lime or lime water, a self-regulating chemical that doesn’t affect the basicity or alkalinity of water, when combined with water makes a fluffy charged solid that helps in filtering smaller particles in water to make it easier to be removed.
  • Flourosilicic Acid – also called as Hydroflourosilicic acid, can also be in powder form and known as Sodium Flouride. Flourosilicic Acid is a synthetic toxic chemical that aids in purifying drinking water as well, and though very small levels can cause grave health problems this chemical reagent helps by killing microscopic microorganisms present in drinking water.
  • Sodium Silicoflouride – also known as Sodium Flourosilicicate, aids in neutralizing Flourosilicic Acid with the Sodium Chloride or Sodium Sulfate and lowers down the toxicity level of Flourosilicic Acid when it is combined with water.
  • Sodium Chloride – derived from salt and sodium as well, helps regulate the toxicity of Flourosilicic Acid when also mixed with water with the help of Sodium Silicoflouride or Sodium Flourosilicicate


Protecting Our Welfare and Our Family’s Health

With this few list of chemicals in drinking water none of them is safe at all. What more if all chemical reagents that weren’t listed will be used in our drinking water?

And aside from the chemicals mentioned, that doesn’t even include lead, copper, aluminum and plastic, the heavy metals that are found in water lines when water passes through and into our home.

For some instance that these chemicals, though only meant as reagents to help purify water, weren’t removed from our drinking water can gravely affect not just our health but the whole family as well.

As a member of the family, we want to make sure that each of us is safe from harm and diseases and find ways, to not only maintain but also to improve, our health by making sure that we keep them nutritionally healthy, hydrated and only gives them the purest drinking water without the presence of toxins. Well now we can.

Scientifically tested and proven, Berkey have microfilaments to make sure that the smallest particle will be filtered and removed from our drinking water. You can now have an assurance that your family is safe, hydrated and healthy with the use of our Berkey water filters.
