About Big Berkey Water Filters

Top 3 ways a Berkey Water Filter will benefit your life

Drink To Your Health. Berkey water filter systems are far superior to other filtration systems because they remove harmful pathogenic bacteria, cysts, parasites, and unhealthy chemical contaminants such as Chlorine to levels higher than 99.99%, while at the same time leaving in the essential minerals your body needs.
Did you know that over 60% of US municipal water is fluoridated? Berkey water filter systems also distinguish themselves from many other filtration systems by having the capabilities to significantly reduce fluoride and arsenic via the "PF" line of filters.

Affordability. Each durable Black Berkey Water filter will last up to 3000 gallons (6000 gallons per set of 2). This is much longer than the majority of water filter solutions on the market.
At 10 gallons per week, this equates to more than 11.5 years of healthy clean drinking water!
Including fluoride and arsenic reduction, 1 gallon of Berkey water costs just 7 cents!.
Stop and think how much money you could save by the simple reduction in bottled water purchases by regularly using water filtered by your Berkey water filter.

Versatility. Berkey Water Filter systems are capable of purifying both treated water (municipal/city water) and untreated raw water from such sources as remote lakes, streams, stagnant ponds, and water supplies in foreign countries.
The micro-pores within the self-sterilizing and re-cleanable Black Berkey water filter purification elements are so small that pathogenic bacteria are simply not able to pass through them.
Due to the fact that the Berkey water filters do not require electricity and are portable, they become a lifesaver during times of flooding, loss of electricity, and other life threatening emergencies.

    • Life in the Gutter May Offer Benefits

      Turns out life in the gutter is not all bad. Scientists have just discovered that gutters lining the streets of Paris are teeming with microscopic life that may help improve water quality of urban storm water runoff. The research team, comprised of biologists from the BOREA Biology of Aquatic Organisms and Ecosystems research unit in France and a fellow scientist from the Max Planck Institute for Terrestrial Microbiology in Germany, have found that gutters running alongside Parisian streets provide an oasis for a myriad of microscopic organisms, including fungi, microalgae and sponges, as well as mollusks. These urban aquatic communities may provide beneficial ecological services, for example helping to clean storm water and reducing urban waste by breaking down solid organic matter as well as urban contaminants such as engine oil and vehicle exhaust fumes that could otherwise degrade water quality. Gaining a clearer understanding of what organisms make up these communities, and the ecological niche they fill, can help us better understand the ecological services that gutter ecosystems render. A storm water drain in Paris The results of the study, which is the first to shed light on the complex biodiversity of microorganisms living on the streets of Paris, appeared in the October 2017 edition of the ISME Journal. After noticing the characteristic brown and green tinge of the water flowing in Paris city gutters, as well as bubbles — which are a tell-tale sign of photosynthesis taking place, BOREA researchers suspected that there may be microalgae present in the water. So they set about analyzing non-potable water samples they collected from various locations to identify what microorganisms were present. Sample sites included street gutters, water outlets located on street curbs that pump water from either the Seine or the Canal de l'Ourcq which is used for street cleaning, as well as water collected directly from the Canal de l'Ourcq and the Seine. They identified a remarkable 6,900 possible species of eukaryote microorganisms in the roughly one hundred water and biofilm samples they collected off the streets of Paris. Unicellular diatoms were the most abundant, but other unicellular eukaryotes (organisms with a nucleus and organelles) such as amoebas, Rhizaria and alveolates; fungi (including species that are recognized as decomposers); sponges; and even mollusk species were observed. More surprising, the researchers around 70% of the species detected in gutter water were not present in the non-potable source water. The composition of the microorganism communities varied greatly between the sites sampled, which according to the researchers, suggests they may originate as a result of human activity or that they have adapted to thrive in the specific urban location where they are found. The researchers conclude that gutters on city streets and the microorganisms they support seem to represent a unique ecosystem that may have a specific, but as yet undiscovered, ecological role to fulfill. Clearly intrigued, the scientists stress that we need to know more about these microorganisms: What exactly are they? What function do they serve? Do they play a key role as minute curbside treatment plants, helping to clean wastewater? How have they adapted to life on the city streets? Should we be monitoring them more closely? To answer these questions, the researchers hope to expand this study by looking at other forms of life, such as bacteria, over a longer timeframe, and assessing microscopic life in gutter water of other cities too.

    • Prenatal Exposure to Fluoride in Mother's Womb Linked to Reduced Intelligence in Kids

      Pregnant women who have high levels of fluoride in their urine are more likely to give birth to children with lower IQ levels, a new study has found. The study, conducted by a team of researchers from the University of Toronto together with experts from the National Institute of Public Health of Mexico, University of Michigan, McGill University, Indiana University, Mount Sinai School of Medicine and Harvard School of Public Health, is the first study of this size and scope that examines the effect of fluoride exposure across multiple stages of neurodevelopment in children. "Our study shows that the growing fetal nervous system may be adversely affected by higher levels of fluoride exposure," said Dr. Howard Hu, Professor of Environmental Health, Epidemiology and Global Health at the Dalla Lana School of Public Health, and principal investigator of the study. "It also suggests that the pre-natal nervous system may be more sensitive to fluoride compared to that of school-aged children."   For over 60 years, people living in the United States and Canada have been exposed to fluoride in their drinking water as well as dental products, which both have fluoride routinely added in order to prevent dental cavities and strengthen bones. In many other countries around the world it is also added to table salt and milk for the toted health benefits it provides. However, many argue that the health risks far outweigh any health benefits that fluoride offers, and water fluoridation needs to be abolished or at least more strictly controlled. This has fueled a greater interest by the scientific community to explore the issues, particularly the effect that exposure to fluoride has on the developing brains of young children, so that they can provide informed input so that drinking water standards can be regulated accordingly. Previous studies have shown that continued exposure to recommended levels of fluoride in Canada and the US can cause some side effects such as mild dental staining, while exposure to fluoride at concentrations 5-10 times higher than the recommended levels can cause fluoride to accumulate in the bones — a condition known as skeletal fluorosis. Yet, according to Hu, "Relatively little is known, with confidence, about fluoride's impact on neurodevelopment." The study, which was recently published in the scientific journal Environmental Health Perspectives, looked at data collected from 287 Mexico City mother-child pairs who participated in the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) project, where pregnant women were recruited between 1994-2005, who, together with their children, have been monitored ever since. The researchers analyzed urine samples collected from the mothers during their pregnancy, as well as urine samples collected from their children when they were between 6 and 12 years old, to get a clearer indication of the personal fluoride exposure of both the mother and their child. "This is significant because previous studies estimated exposures based on neighborhood measurements of drinking water fluoride levels, which are indirect and much less precise measures of exposure. They also looked at children's exposures instead of prenatal exposures or had much smaller sample sizes of subjects to study," explains Dr. Hu. The research team then examined the link between fluoride levels in urine and the verbal, quantitative and perceptual performance, as well as memory and motor skills of children at 4 years old, and again when they were between 6-12 years old. They also took other factors that are known to affect child neurodevelopment into account, including: birth weight, gestational age when born, birth order, and child's sex, as well as mother's marital status, socioeconomic status, IQ, education, age at delivery, smoking history and lead exposure. The study found that levels of urinary fluoride where slightly higher in pregnant women compared to non-pregnant women in the US and Canada. However, according to Dr Hu, the study's findings don't provide sufficient information to suggest that there is no safe level of fluoride exposure. "The potential risks associated with fluoride should be further studied, particularly among vulnerable populations such as pregnant women and children, and more research on fluoride's impact on the developing brain is clearly needed."
