Big Berkey® System

In today’s unpredictable world where a nuclear event such as a power plant accident, terrorist attack, or even international nuclear war could introduce radiological contaminants into our country’s environment (including critical infrastructure such as water supplies), having a disaster preparedness plan in place has never been more important. This should include having a water filter that’s been tested to remove or dramatically reduce specific radiological contaminants in your water supply—such as a Big Berkey® gravity-fed water filtration system equipped with powerful Black Berkey® Elements.

Recently, popular consumer health advocate and award-winning investigative journalist Mike Adams (“The Health Ranger”) had testing conducted on 28 water filtration systems for the removal of cesium-137—a radioactive isotope of cesium—and reported his findings.

Of the 28 systems tested, only six reduced cesium by greater than 99%. Adams’ testing showed that the Big Berkey® system removed an impressive 99.99% of cesium-137 in the lab’s test sample—reducing the tested isotope count from 78,000+ parts per billion down to a miniscule 7.1 parts per billion. Note that the three systems which had equal cesium reduction (one system, 99.99%) or slightly greater reduction (two systems, 100%) compared to the Big Berkey® system are also quite small—and thus can filter a limited amount of water at a time. The Big Berkey® system can filter and hold up to 2.25 gallons, making it the best high-capacity system tested. 

You can read more about Adams’ testing at the Natural News website, and watch his 30-minute report below (it is also posted on Mike Adams’ free-speech media platform, which you can see here). In the video, the first 10 minutes or so are spent discussing the dangers of cesium and how the tests were conducted, along with information about the equipment used in the tests. The Big Berkey® system is mentioned at the 13:06 mark.

Black Berkey® Elements Dramatically Reduce Other Radiologicals As Well

New Millennium Concepts, Ltd. has had testing conducted by accredited, third-party labs on Black Berkey® Elements for their ability to reduce other radiologicals that may be present in water. Testing showed a 98.7% or greater reduction of potential gross alpha contaminants, including: uranium-235 and -238, plutonium-238 and-239, radium -226 and -228, and more. Testing showed a 95.3% or greater reduction of potential gross beta contaminants, including: iodine-129 and -131, cobalt-60, nickel-63, strontium-90, and more. Black Berkey® Elements test results can be viewed here.

Choose a Water Filter System With a Large Capacity and Long Filter Lifespan

Note that a number of the systems tested are of the pitcher-type variety, which can process only small amounts of water at a time and use filters that require replacement after a relatively small number of gallons.

But in a long-term shelter-in-place or bug-out scenario, a much larger system with greater capacity would be necessary. Berkey® systems come in 6 sizes—the Big Berkey® system shown in the test holds 2.25 gallons; our largest system—the Crown Berkey™ system—can hold up to 6 gallons. These systems are equipped with Black Berkey® Elements which can filter up to 6,000 gallons of water per pair of elements before replacement is recommended, depending on quality of influent water.

Each additional pair of Black Berkey® Elements installed in your system increases its flow rate, while adding another 6,000 gallons of filtration before filter replacement is recommended. The Crown Berkey™ system, when equipped with a maxiumum of 8 Black Berkey® Elements, can filter up to 24,000 gallons of water before filter replacement is recommended.

Beyond Radiologicals: Berkey® Gravity-Fed Water Filter Systems Address a Broad Array of Contaminants

And while radiological water contamination is a concern of some consumers, Berkey® gravity-fed water filtration systems equipped with powerful Black Berkey® Elements have been independently tested to remove or dramatically reduce over 250+ more common (and increasingly often in the news) contaminants that may be present in drinking water such as:

  • Perfluorinated chemicals (PFAS)
  • Heavy metals
  • VOCs
  • Pharmaceuticals
  • Pesticides
  • Trihalomethanes
  • Inorganic minerals
  • Petroleum products
  • Rust silt, sediment and more
