Black Berkey Filters are designed to outlast all of our competition. We pride ourselves on our ability to provide lasting value through economy. Our main purification element, the Black Berkey, was engineered to last for literally years. Even with the most economical water filtration device on the market, our filtering elements still need to be replaced at some point during their long life. When that time comes we offer replacements built to the exacting standards you have come to expect and rely on from Berkey. The Berkey Fluoride Filter removes Fluoride from your drinking water. Our Shower Filter Replacement allows you to use your existing shower head or replace the filter on the Berkey shower filter.
