* Please note that in all the testing conducted on the Black Berkey purification element, reduction occurred in excess of the reporting limit for each test. In other words, the reduction levels achieved, in every case, exceeded the testing limitation of the laboratory in which the tests were conducted. What this means is that the reduction levels indicated on the enclosed test results are a minimum that can be achieved; real world results may actually be greater than the percentages listed. For example the lab could only test total Haloacetic Acids (HAAS) removal up to 98%.
