Black Berkey®

Overview Black Berkey filter elements are high-powered purifiers for the removal of water contaminants, backed by laboratory testing to exceed NSF / ANSI 53 standards. A detailed list is available. Exceptional efficiency: Filters tap, rain, lake, river, fountain, pond and well water.
Their durability is indisputable: Unlike some expensive disposable filters, Black Berkey filters can be cleaned with an ordinary kitchen sponge (green abrasive side) when you notice a certain slowness in filtration flow.
They can be stored (packaged) indefinitely in a moisture-free environment after air-drying.
Thanks to its composition of coconut charcoal (microfiltration) and ionized silver, it lets through minerals essential to our bodies, while eliminating viruses and pathogenic bacteria (pesticides, nitrate, heavy metals, drug residues, etc.).  

  *Their durability is shortened over time by regularly filtering water from a source other than tap water.
