How the Royal Berkey® Works The Royal Berkey® uses gravity to draw water through Black Berkey® filtration elements. Simply fill the upper chamber, allow gravity to do the work, and dispense filtered water from the lower chamber. Black Berkey® Elements Each Royal Berkey® system includes 2 Black Berkey® Elements and can be expanded to accommodate up to 4 elements. Black Berkey® Elements are designed to reduce a broad range of potential contaminants commonly found in drinking water supplies, including: Lead and mercury Chlorine and chloramines VOCs Trihalomethanes (THMs) Pharmaceutical residues Petroleum-related compounds Rust, sediment, and particulates Radiological contaminants The elements are also designed to retain beneficial minerals such as calcium and magnesium. Each Black Berkey® Element is rated for approximately 3,000 gallons of filtration. With two elements installed, the system can filter approximately 6,000 gallons before replacement is recommended. Optional PF-2™ Fluoride & Arsenic Reduction Filters may be added to the lower chamber. The Royal Berkey® can accommodate up to 4 PF-2™ filters.
