Black Berkey Purification

Category: Tags: ,

Description

Many water filters on the market may claim to be a water purifier, but do not meet the performance specifications required for this classification. In order to be classified as a water purifier, a water treatment device must remove at least 99.9999% of pathogenic bacteria and reduce viruses by 99.99%. The Black Berkey Purification Elements can be classified as water purifiers because they remove 99.9999999% of pathogenic bacteria and 99.999% of viruses, which greatly exceeds the standard. The Black Berkey Purification Element formulation has been tested by State and EPA accredited laboratories to exceed NSF/ANSI Standard 53.
