The Super Sterasyl™ Filters are primarily composed of diatomaceous earth compressed into ceramic filter shells that effectively reduce larger common contaminants found in freshwater souces through microfiltration. The ceramic filter also contains granular activated carbon to reduce organic chemicals and improve the color, taste, and odor of drinking water. Super Sterasyl™ Filters last for 535 gallons or six months per filter.
We recommend replacing Black Berkey® Elements every 3,000 gallons (6,000 per set of 2 elements). Black Berkey® Elements may require replacement sooner based upon the quality of influent water. These elements reduce everything the Super Sterasyl™ Ceramic Elements will. In addition, Black Berkey® Elements dramatically reduce trihalomethanes, inorganic minerals, heavy metals, pharmaceuticals, pesticides, VOCs, petroleum products, perfluorinated chemicals, rust, silt, sediment, radiologicals and more.
Black Berkey® Elements are capable of greater contaminant reduction and a longer lifespan than virtually any of the other filter elements on the market.
