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 […]
What is ORP? ORP stands for Oxidation Reduction Potential or Redox. It is the activity or strength of oxidizers and reducers in relation to their concentration in water. It is not (like pH) a measurement of concentration, rather of activity level. Different meters are available to measure the ORP in your water. ORP is measured […]
Our Black Berkey® Purification elements are a proprietary blend of several different media types including high grade coconut shell carbon.
Dehumidifiers that use refrigeration will have cold metal tubes to turn water vapor from a gas to a liquid. According to the EPA, stagnant condensate water can harbor biological contaminants, including mold, mildew and algae, especially if the collection bucket isn’t cleaned regularly. These contaminants have the potential for causing diseases such as hypersensitivity pneumonitis […]
Yes it is normal and not unusual for the last 1.3 cm. to 2.5 cm. of water to remain in the upper chamber. By design the water must pass through very fine micro pores within the elements in order to pass from the upper chamber to the lower. The lower the water level in the […]
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 […]
