When drinking water that’s been filtered using a Black Berkey Filter, you can rest assured that your water is clean and safe for consumption. In fact, Black Berkey purification elements are far more powerful compared to
competitors’ water filters. We tested the filters with more than 10,000 times the concentration of harmful pathogens per liter of water than is required by industry-standard test protocols. This concentration of pathogens is so high that the water exiting the filters should be expected to contain a concentration of 100,000 or more pathogens per liter (
99.99% reduction — the requirement in order to be classified for pathogenic removal). Incredibly,
Black Berkey water filter elements removed 100% of the pathogens. After using the Black Berkey Filters, absolutely no pathogens were found in the effluent or were able to be detected. This set a new standard, allowing us to classify all systems containing the Black Berkey Filters as purifiers.
