(NaturalNews) When it comes to the removal of heavy metals and toxic elements from water, Big Berkey water filters easily beat ProPur and other filters in the market. According to independent lab tests conducted at the Natural News Forensic Food Labs and published online today.

Big Berkey also best at removing elements with radioactive isotopes
In this scientific assessment, we tested for the ability of popular off-the-shelf water filters to remove heavy metals such as lead, cadmium, arsenic and mercury as well as elements that have radioactive isotopes such as strontium, cesium and uranium. Finally, we also tested for aluminum reduction due to the chemtrails concern among many consumers today.

Big Berkey was by far the best-performing gravity water filter we tested, achieving near-total removal of all toxic elements when used with the attached arsenic / fluoride filters (which attach underneath the black ceramic filters).

Product assembly was straightforward and simple, and all the parts in the unit worked reliably.

When it comes to reliable removal of toxic elements such as lead, cadmium, arsenic and even uranium, Big Berkey is the best performing gravity water filter available on the market today.

Reduction of elements by Big Berkey:

These ceramic filters are excellent at removing harmful bacteria from sediment heavy, contaminated drinking water. It soon became clear to Berkey that a more powerful filter was needed, one that not only removed bacteria but was also, in addition, able to remove chemicals, viruses, heavy metals, fertilizers and a long list of additional contaminants from your drinking water.
  • Aluminum: 86.6%
  • Copper: 100.0%
  • Arsenic: 100.0%
  • Strontium: 100.0%
  • Cadmium: 100.0%
  • Cesium: 98.6%
  • Mercury: 99.8%
  • Lead: 100.0%
  • Uranium: 100.0%

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.

What is the difference between the Black Berkey purification filters and the white Ceramic filters?
Therefore, if the bladder tank is not sterilized on a regular basis, it becomes a source of bacteriological contamination that is never exposed to UV. Additionally, the carcasses of the dead bacteria remain within the drinking water with an RO system whereas they are removed by the Black Berkey filters.

Why do you need a Water Filter?

The water that comes directly from the faucet, the tap water, may already be damaging your health without you noticing it. Water is very important as it sustains life, you can survive without food for about 30 days, but can survive without water for only 1-3 days’ maximum.

Although the water is tested, and the Environmental Protection Agency stated that more than ninety percent of the water supply in the United States is actually safe to drink, they are not entirely free from impurities like chlorine, metals, ions, chemical, fluoride, and pesticides amongst the many.

The water that is flowing from the tap is not actually something that you would think as entirely clean. Before it reached the faucet in your home, it has already travelled through miles and miles of pipeline and it has picked lots of contaminants along the way. This is why you need to consider using a water filtration system to help you improve the water quality and for health purposes.

They Remove Lead

Lead is a chemical element with symbol Pb and atomic number 82. It is a heavy metal with a density exceeding that of most common materials; it is soft, malleable, and melts at a relatively low temperature.

Lead can enter drinking water when service pipes that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. The most common problem is with brass or chrome-plated brass faucets and fixtures with lead solder, from which significant amounts of lead can enter into the water, especially hot water.

Homes built before 1986 are more likely to have lead pipes, fixtures and solder. The Safe Drinking Water Act (SDWA) has reduced the maximum allowable lead content — that is, content that is considered “lead-free” — to be a weighted average of 0.25 percent calculated across the wetted surfaces of pipes, pipe fittings, plumbing fittings, and fixtures and 0.2 percent for solder and flux.

Lead can be removed from the water when you let the water pass through a filter that uses a reverse osmosis mechanism, a carbon filter or distillation that was specifically designed to remove the metal out of your drinking water. It is very important that lead is removed from the water that you drink because it could be toxic when ingested. Lead could commonly get into your drinking water by seeping into your water supply when it passes through the old plumbing pipelines or the solder that is used for them to join together.

If your major source of water is a well, health authorities recommend that you will need to have the water tested for at least once a year for any lead of other kinds of contaminants.

They Remove Chlorine

Chlorine is a chemical element with symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them.

Chlorine readily combines with chemicals dissolved in water, microorganisms, small animals, plant material, tastes, odors, and colors. These components “use up” chlorine and comprise the chlorine demand of the treatment system. It is important to add sufficient chlorine to the water to meet the chlorine demand and provide residual disinfection.

The chlorine that does not combine with other components in the water is free (residual) chlorine, and the breakpoint is the point at which free chlorine is available for continuous disinfection. An ideal system supplies free chlorine at a concentration of 0.3-0.5 mg/l. Simple test kits, most commonly the DPD colorimetric test kit (so called because diethyl phenylene diamine produces the color reaction), are available for testing breakpoint and chlorine residual in private systems. The kit must test free chlorine, not total chlorine.

Most of the water utility companies choose to use chlorine as a medium of cleaning tap water because it’s easy to use, an inexpensive choice and it is actually very effective in killing off bacteria that is found in the water. Chlorine can also be very effective in eliminating viruses in the water.

Although chlorine is actually a good and an effective disinfectant, it can make your drinking water smell and taste not good, your water could be very unpleasant. The chlorine could also react with other metals that can be found in the water, therefore, forming a hazardous compound.

Many cities all over the world make use of chlorine to clean their water supply, although this process is actually very important to make sure that we have a clean drinking water that is free from microorganisms that could badly affect our health, chlorine is basically bleach and it also carries a lot of health risks with it, it even puts you at a higher risk of developing rectal and bladder cancer amongst the many complications.

They Remove Pathogens

In biology, a pathogen in the oldest and broadest sense is anything that can produce disease; the term came into use in the 1880s. Typically the term is used to describe an infectious agent such as a virus, bacterium, protozoa, prion, a fungus, or other micro-organism.

Because all of the pathogens that can come through public water supplies, often in small amounts that can grow into large colonies when in the right conditions, all water must be effectively treated in order to remove them. In addition to treating the water itself, managers of water supplies must also keep their infrastructure clean and free of biofilms, groupings of microorganisms that have adhered to one another and/or a surface. These biofilms grow on any surface that water touches and harbor any and all microbes that that become part of the community. Biofilms, as a microbial community, work together to protect themselves from disinfection, so any presence of biofilm presents a danger.

There are several substrates including pathways where the pathogens can invade a host. The principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. Diseases caused by organisms in humans are known as pathogenic diseases.

You need to keep parasites and bacteria out of your drinking water because they could be a grave threat to you and your family’s health.

Cryptosporidium, and what even made this parasite dangerous is because it is resistant to chlorine, so it really needs to be filtered out using a mechanical filter. A lot of pathogens could be omitted from your water by passing it through an ultra, a micro or a nano filter.

Giardia intestinalis is a microscopic parasite, this organism can survive and thrive in an environment for a long time, it could take up to several months. This parasite causes Giardiasis which is a kind of an illness which causes diarrhea that could last for six weeks. The microscopic parasite that causes that kind of illness, along with other of its kinds, can be ingested from the water that was contaminated with human or animal feces.

They Remove Fluoride

Fluoride, is an inorganic, monatomic anion of fluorine with the chemical formula F− . Fluoride is the simplest anion of fluorine.

Fluorides are chemical compounds that help prevent tooth decay. They are found in nature – in rocks and soil, in fresh water and in ocean water. They are also found in some types of food.

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.

Decades of research have shown that adding fluoride to water (fluoridation) helps prevent tooth decay. In some communities, natural levels of fluoride in the water supply match the optimal level to prevent tooth decay. In many others, the level of fluoride is too low and has to be added to the water supply. In Canada, the optimal range for fluoride in drinking water suggested by Health Canada is 0.7 milligrams per liter (mg/L)
Fluoride is added to most toothpastes, soil fertilizers and even water systems that had caused an alarm worldwide. Anything in excess is not beneficial. This act makes users prone to over consumption of the mineral that can cause serious health damage.

We only need a small amount of the mineral fluoride.  Excessive amount of it can be toxic to our health. Irrefutable evidence shows that high fluoride consumption is directly associated to gastrointestinal problems, low fertility, thyroid and endocrine related ailments and even cancer.

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 suggest 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 laboratory.

Beneficial Minerals Information

The technology utilized in the Black Berkey™ purification elements is designed not to remove ionic minerals from the water. The elements are however, designed to remove sedimentary minerals. Additionally, in order to reduce heavy metals, there are several types of media used in the proprietary formulation that have a specific affinity for heavy metals. The best part is that the media used in the Black Berkey™ elements is designed to not remove beneficial minerals. Because the media formulation does not have an affinity for beneficial minerals such as calcium and magnesium, these minerals should pass right on through the elements.

*Beneficial minerals that are recommended for the human body are typically categorized into two different groups:
– Major Minerals : Minerals that are recommended in our diet at recommended amounts greater than 100mg/day.
– Trace Minerals: Minerals that are recommended in our diet at recommended amounts less than 100mg/day.

Calcium Strong bones & muscles, cardiovascular health, tooth & bone formation
Chloride Helps create cells
Magnesium Heart Regulation, relaxes muscles
Phosphorus Tooth & bone formation
Potassium Sends oxygen to the brain, blood pressure, nerve & muscle function
Sodium Nerve & muscle function and maintains the proper balance of water in the body
Sulfur Helps stabilizes protein structures-hair, skin, nails
Chromium Glucose function – makes sure every cell gets energy as & when needed
Cobalt Supports red blood cell production and the formation of myelin nerve coverings.
Copper Metabolic process, blood cell production; helps create hemoglobin-to carry O2 in blood.
Fluoride Increases the structural stability of teeth and bones
Iodine Assists thyroid hormone production, helps make thyroid hormones
Iron Blood production, disease resistance, production of amino acids, natural muscle building & maintaining healthy red blood cells
Manganese Nervous System function, bone strength, enzyme production & activation
Molybdenum Enzyme production & activation
Selenium Immune function; protects cells from damage
Silica Necessary for the formation of collagen for bones and connective tissue

* NOTE : Beneficial Mineral Information based upon Internet and other informational research and believed to be accurate at time of publication. Ongoing research and developments can change current conventional wisdom and recommendations regarding different beneficial minerals. When in doubt, it is always a good idea to consult your local health practitioner.

Waterborne Diseases – are caused by pathogenic microorganisms that most commonly are transmitted in contaminated fresh water. Infection commonly results during bathing, washing, drinking, in the preparation of food, or the consumption of food that is infected. Various forms of waterborne diarrheal disease probably are the most prominent examples, and affect mainly children in developing countries; according to the World Health Organization, such diseases account for an estimated 3.6% of the total DALY global burden of disease, and cause about 1.5 million human deaths annually. The World Health Organization estimates that 58% of that burden, or 842,000 deaths per year, is attributable to unsafe water supply, sanitation, hygiene and cleanliness.

What Chemicals are in tap water?

The chemicals found in ordinary tap water are known to be very common. Public drinking analysis done by experts have uncovered that tap water contains over 2000 different types of toxic chemicals. This makes owning a water purification very important. The only healthy and safe way to drink ordinary tap water is to use a water purification.

Chemical Sources

Chemicals will enter into tap water from many different types of sources. Pollution is one way that chemicals have gotten into the tap water supplies. Other ways are when chemicals are added to the water by the public water systems. The most common of these chemicals is chlorine. Chlorine is the most common of the types of chemicals currently being used to treat public water supplies. It is used to remove and to kill any bacteria which could be living in the water. This type of treatment prevents people from getting ill from drinking unsanitary water.

Health Risks From Chemicals

Even though chemicals are added to tap water to purify it for drinking and cooking in homes, there are still health risks. Adding chlorine to water is actually adding a poison to the water we drink. Over time, chlorine taken in small doses will increase the risk of cancer, heart disease and other health conditions. Most all public drinking water systems use chlorine to purify water.
Other chemicals which are found in drinking water are equally as deadly. Chemicals, such as pesticides and fertilizers in drinking water have been linked to birth defects. Yet, chemicals have been used for years to purify drinking water by killing the parasites that live in it. However, experts say that these parasites are becoming immune to the chemicals and are living after purification treatments. These types of parasites will cause serious health problems in your digestive system.

How Dangerous Is Tap Water?

Is tap water really that bad for us to drink? The government regulates the processing of drink water through the EPA and FDA. They are aware that dangerous chemicals may still remain in the drinking water. While there are standards in place for the maximum amount of contaminants allowed in water, none of these levels are at zero. Meaning, that there are dangerous toxins in the water which we drinking from the tap. Large increases in cancers and other diseases have been reported in places where there has been poor processing of water purification systems.

Some Types of Chemicals in Drinking Water

This is a brief list of the types of toxins in drinking water and what effects they can have on your health.
1. Chlorine – Can cause bladder and rectal cancers, and also asthma. Recently, experts have linked chlorine to breast cancer.
2. Lead – Lead enters tap water through corroded pipes. Lead in drinking water is harmful for pregnant mothers and children. Lead poisoning has been proven to cause learning disorders and severe developmental delays.
3. Giardia and Cryptosporidium – These types of protozoa are responsible for widespread and severe outbreaks of gastro-intestinal diseases. They will make their way in the water system whenever here has been a sanitation breakdown.

7 Science-Based Health Benefits of Drinking Enough Water

Our bodies are around 60% water, give or take.
It is commonly recommended to drink eight 8-ounce glasses of water per day (the 8 x 8 rule).
Although there is little science behind this specific rule, staying hydrated is important.
Here are 7 evidence-based health benefits of drinking plenty of water.

1. Water Helps to Maximize Physical Performance

If we do not stay hydrated, physical performance can suffer.
This is particularly important during intense exercise or high heat.
Dehydration can have a noticeable effect if you lose as little as 2% of your body’s water content. However, it is not uncommon for athletes to lose up to 6-10% of their water weight via sweat.
This can lead to altered body temperature control, reduced motivation, increased fatigue and make exercise feel much more difficult, both physically and mentally.
Optimal hydration has been shown to prevent this from happening, and may even reduce the oxidative stress that occurs during high intensity exercise. This is not surprising when you consider that muscle is about 80% water.
So, if you exercise intensely and tend to sweat, then staying hydrated can help you perform at your absolute best.
BOTTOM LINE: Losing as little as 2% of your body’s water content can significantly impair physical performance.

2. Hydration Has a Major Effect on Energy Levels and Brain Function

Your brain is strongly influenced by hydration status.
Studies show that even mild dehydration (1-3% of body weight) can impair many aspects of brain function.
In a study of young women, fluid loss of 1.36% after exercise impaired both mood and concentration, and increased the frequency of headaches.

Another similar study, this time in young men, showed that fluid loss of 1.59% was detrimental to working memory and increased feelings of anxiety and fatigue.
A 1-3% fluid loss equals about 1.5-4.5 lbs (0.5-2 kg) of body weight loss for a 150 lbs (68 kg) person. This can easily occur through normal daily activities, let alone during exercise or high heat.
Many other studies, ranging from children to the elderly, have shown that mild dehydration can impair mood, memory and brain performance.
BOTTOM LINE: Mild dehydration (fluid loss of 1-3%) can impair energy levels and mood, and lead to major reductions in memory and brain performance.

3. Drinking Water May Help to Prevent and Treat Headaches

Dehydration can trigger headaches and migraines in some individuals.
Several studies have shown that water can relieve headaches in those who are dehydrated.
However, this appears to depend on the type of headache.
One study of 18 people found that water had no effect on the frequency of headaches, but did reduce the intensity and duration somewhat.
BOTTOM LINE: Drinking water can sometimes help relieve headache symptoms, especially in people who are dehydrated.

4. Drinking More Water May Help Relieve Constipation

Constipation is a common problem, characterized by infrequent bowel movements and difficulty passing stool.
Increasing fluid intake is often recommended as a part of the treatment protocol, and there is some evidence to back this up.

Low water consumption appears to be a risk factor for constipation in both young and elderly individuals.
Carbonated water shows particularly promising results for constipation relief, although the reason is not entirely understood.
BOTTOM LINE: Drinking plenty of water can help prevent and relieve constipation, especially in people who generally do not drink enough water.

5. Drinking Water May Help Treat Kidney Stones

Urinary stones are painful clumps of mineral crystal that form in the urinary system.
The most common form is kidney stones, which form in the kidneys.
There is limited evidence that water intake can help prevent recurrence in people who have previously gotten kidney stones.
Higher fluid intake increases the volume of urine passing through the kidneys, which dilutes the concentration of minerals, so they are less likely to crystallize and form clumps.
Water may also help prevent the initial formation of stones, but studies are required to confirm this.
BOTTOM LINE: Increased water intake appears to decrease the risk of kidney stone formation. More research is needed in this area.

6. Water Helps Prevent Hangovers

A hangover refers to the unpleasant symptoms experienced after drinking alcohol.
Alcohol is a diuretic, so it makes you lose more water than you take in. This can lead to dehydration.
Although dehydration is not the main cause of hangovers, it can cause symptoms like thirst, fatigue, headache and dry mouth.
A good way to reduce hangovers is to drink a glass of water between drinks, and to have at least one big glass of water before going to bed.
BOTTOM LINE: Hangovers are partly caused by dehydration, and drinking water can help reduce some of the main symptoms of hangovers.

7. Drinking More Water Can Help With Weight Loss

Drinking plenty of water can help you lose weight.
This is due to the fact that water can increase satiety and boost your metabolic rate.
In two studies, drinking half a liter (17 ounces) of water was shown to increase metabolism by 24-30% for up to 1.5 hours.
This means that drinking 2 liters of water every day can increase your total energy expenditure by up to 96 calories per day.
The timing is important too, and drinking water half an hour before meals is the most effective. It can make you feel more full, so that you eat fewer calories.
In one study, dieters who drank half a liter of water before meals lost 44% more weight, over a period of 12 weeks.
It is actually best to drink water cold, because then the body will use additional energy (calories) to heat the water to body temperature.
