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 […]
Black Berkey® Purification Elements don’t necessarily need to be cleaned every time one cleans their Berkey® unit. However, this can vary depending on your area and water source. In certain areas, the water is much dirtier than normal, and will necessitate cleaning the elements more frequently; possibly even more than cleaning the rest of the system requires. If […]
