Laboratory tests of Black Berkey filters

RESULTS OF LABORATORY TESTS

The Black Berkey® purification elements, which have been laboratory tested, eliminate or significantly reduce the contaminants listed below:

Many water filters on the market may claim to be a water purifier, but they do not meet the performance specifications required for this classification. To be classified as a water purifier, a water treatment device must eliminate at least 99.9999% of pathogenic bacteria and reduce viruses by 99.99%. Black Berkey® purification elements can be classified as water purifiers because they eliminate 99.9999% of pathogenic bacteria and 99.999% of viruses, far exceeding the standards. Tested by accredited laboratories.
