The latest designs of Berkey® “Super Sterasyl” ceramic water filter elements incorporate pure silver impregnated into a porous ceramic outer shell [80,000,000 pores] that can trap waterborne bacteria down to as low as .22 of a micron in particle size [1/100,000 of an inch]. Laboratories consider a filtering medium with an effective pore size of .01 micron to .45 micron to be bacteriologically sterile and .45 micron to 1.0 micron to be bacteriologically safe. Regrowth of bacteria that becomes trapped either on the outside of the Berkey element or in the ceramic’s pores are controlled by the silver which, on contact with water, releases small quantities of positively charged metals ions. These ions are taken into the enzyme system of the bacteria’s cell and thereby neutralize it. The flow rate of the ceramic filter can be easily renewed by simply brushing its outer surface under running water. As the top layer of ceramic and the contaminants are brushed off and flushed away, a new layer becomes available. This process can be repeated dozens of times before the Berkey Sterasyl ceramic shell is exhausted.
KIESELGUHR CERAMIC – STAGE ONE
Berkey® ceramic is made from Kieselguhr Diatomaceous Earth and fired at incredibly high temperatures. Over 80,000 overlapping pores make up each Berkey element. This feature provides absolute mechanical filtration to .9 of a micron (.5 ANSI). 99.99% rejection of bacteria and cysts. Bacteria and any other foreign particles that my be present in your water are trapped on the outside of the element while the water passes through the ceramic wall to the inside of the element.
WHY BACTERIOSTATIC ?
This simply means self sterilizing. The entire ceramic wall is impregnated with pure silver. Silver has been long proven as a disinfectant which insures that bacteria trapped in the ceramic’s pores are killed thereby eliminating any threat of bacteria colonization.
THE CORE – STAGE TWO
Inside the Berkey Ceramic shell is a post filter which is manufactured by using a treated granular carbon to form a tightly packed matrix. This post filter provides Chemical Reduction of chlorine, pesticides, solvents, etc
