The Black Berkey purification element formulation has been tested by State & EPA accredited laboratories to exceed NSF/ANSI Standard 53.Black Berkey Purification Elements are more powerful than any other gravity filter element currently available. The micropores within the cleanable BlackBerkeyTM purification elements are so small that viruses and pathogenic bacteria are simply not able to pass through them. Black BerkeyTM purification elements are so powerful, they can remove red food coloring fromwater without removing the beneficial minerals your body needs. Virtually no other filtration element can duplicate this level of performance.The powerful Black Berkey purification elements also remove or reduce viruses, pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, cloudiness, trihalomethanes, silt, sediment, heavy metals, foul tastes andodors, yet they leave in the healthful and beneficial minerals that your body can benefit from.No need for expensive disposable filters. Black Berkey purification elements are cleanable. When the flow rate decreases simply...
