ProOne® innovator Steve Steinway has a vision to transform water filtration products utilizing the newest available technology. We strive to continually expand our filtering methods in order to bring the purest water to our customers. We are here to fight the fight against poor drinking standards and to create healthier water for those in need. 

When drinking water that’s been filtered using a Berkey Black filter, you can rest assured that your water is clean and safe for consumption. In fact, Black Berkey purifier 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, 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!
