Berkey BB9-2 Replacement Black Purification Elements, 4-Pack by Berkey

Black Berkey Purification Elements***** These rigorously-tested purification elements go beyond filtering to purify your water, removing or greatly reducing viruses, bacteria, pesticides, pharmaceuticals, PFCs, organic chemicals, foul tastes and odors, heavy metals like lead and even radiologicals. They not only purify treated water; the powerful elements can purify raw, untreated water from sources such as lakes, ponds, rivers and streams. The long life of the Berkey Purification elements allows you to enjoy purified water for about two cents per gallon. 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 elements have a unique 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.
