This level of effectiveness is achieved through its unique design, which includes a proprietary blend of activated carbon and ion exchange resins.

Effectiveness Against Common Pollutants

Berkey filtration has been tested and proven effective against a wide range of common pollutants found in areas with high pollution levels. These include lead, mercury, and other heavy metals, which are often present in contaminated water sources. In fact, the Black Berkey filter has been shown to remove up to 99.9999% of lead and other heavy metals, making it a reliable option for families living in areas with high levels of industrial pollution.
