Black Berkey® Purification Elements are MORE POWERFUL than any other gravity filter element currently available. The Elements have an exceptional purification capability that is due to their unique structure. The micro-pores within the Black Berkey® Elements are so small that viruses and pathogenic bacteria are simply not able to pass through them. (see How Berkey Systems Work)
- Water filter vs. Water purifier
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 99.9999% of pathogenic bacteria (6
