Utilizes 3-Stage Filtration: Reduces up to 99.99% of pathogenic bacteria, organic chemicals, and particulates.
Stage 1: Diatom Earth Ceramic Filtration
At the heart of Big Berkey water filters are their exclusive Sterasyl element that utilizes the natural properties of highly specialized diatomaceous earth (Kieselguhr), which is extruded and fired into a hollow porous matrix that has a sub-micro pore of 0.5, designed to remove waterborne bacteria.
Impurities unable to penetrate through the microscopic channels of the ceramic matrix, such as bacteria, cryptosporidium and other micro organisms, are simply trapped on or near the surface of the ceramic element. This surface may be easily exfoliated with a brush or Scotch® pad.
Stage 2: Bacteriostatic Silver Impregnation
Impregnation of the ceramic element with silver renders the surface of the cartridge bacteriostatic – that is, bacteria cannot grow on the surface of your Berkey water filter. This ensures that you can change or clean the cartridge without fear of contamination. In contrast to silver impregnation commonly used in activated carbon filters, the small amount (0.07%) of silver in the ceramic element is in a form that will not readily leach out.
Stage 3: Extruded Activated Carbon Block Core
After bacteria-free water leaves the ceramic exterior it enters through the core of this highly activated extruded carbon block. Carbon is proven to reduce chemical contamination including Chlorine, Trihalomethanes (THMs), and VOCs (volatile organic contaminants). In the process of filtering water through carbon, the water retains its mineral and high oxygen content that insures a spring-fresh taste. Click here for performance data sheet.
