What is Leptospira? Leptospira is a bacterium that exists around the world but is most prevalent in hot, wet climates. “Leptospirosis is a bacterial infection caused by certain members of the genus Leptospira. Most people who develop a leptospirosis infection only get mild symptoms, but a bit more serious influenza-like symptoms are also quite common. […]
Plastic Fibers, also known as Microplastics, are small plastic pieces that can enter and contaminate drinking water. Scientists are studying the exact pathways that allow microplastics to enter into the drinking water supply. An extensive investigation on microplastics in water found that these analyses caught particles of more than 2.5 microns in size,” 2.5 microns […]
Yes, silver is used as an antimicrobial to self-sterilize the Black Berkey® elements. Testing was conducted both internally and by Analytical Services, Inc. to insure that the silver used does not leach into the purified water. “All controls samples, including stock samples, analytical positive and negative controls, and the negative control collected prior to seeding […]
Prior to transporting or moving any Berkey® system, the Black Berkey® Purification Elements must first be removed. Failure to remove the elements from the system can result in broken stems. Place the elements in secure and water-tight packaging. The top and bottom of the stainless steel systems nest within each other for easy transport (remove […]
GenX is the trade name for a chemical that was introduced in 2010 as a “safer” replacement for a toxic contaminant known as PFOA (perfluorooctanoic acid, commonly called C8). Like its predecessor, GenX enables the production of common household products including non-stick pans, firefighting foam and water-repellent fabrics. Although few health studies are available on […]
Yes, the base of Black Berkey Purification Element is BPA free.
The media within the Black Berkey® Purification Elements is not designed to remove beneficial (ionic) minerals from your water supply. These kinds of minerals can be reduced if they are in high concentration, but some will still be allowed through. We have not done any testing for the removal rate of ionic minerals, as they […]
What are estrogenic compounds? “Estrogenic compounds are part of a larger category of chemicals known as endocrine-disruptors (EDCs), chemicals that can alter the hormonal and homeostatic systems enabling an organism—like a human being or other animal—to communicate with and respond to its environment.” http://www.arhp.org/publications-and-resources/contraception-journal/august-2011 What types of estrogen are found in drinking water? “The […]
The short answer is Yes! Black Berkey elements have been tested to remove greater than 99.8% of Chromium 6. In fact, Both the Black Berkey purification elements and the Berkey Sport Bottle have laboratory testing, showing both Chromium and Chromium 6 reduction. It is important to note though, that not all forms of Chromium are […]
How are the Black Berkey® Purification Elements able to remove radiologicals for their full lifespan?
Many filter elements can show strong results that quickly decline. As such, we think it to be vitally important, with certain contaminants, that the reduction capability of our Black Berkey® elements be tested over time. Such tests provide the rate of decline in efficiency and allow our customers a verification that the rate of decline […]
