The Original Gravity Filtration System

Now you can enjoy virtually the Most Delicious, Freshest, Healthiest Drinking water possible for pennies a day..... are the ultimate in water filtration used world-wide. To provide virtually the most delicious, sparkling clean water possible in situations where a potable water supply may not be available.

For generations, health-conscious people around the world have recognized that the foundation to a healthy life and healthy body is clean, fresh drinking water. This important essential element is the basis for enjoying your longest, healthiest life. No amount of vitamins or supplements can substitute for the vital life-sustaining properties found in nourishing, healthful drinking water. It is truly the foundation of life.

Unfortunately, securing your access to good-tasting, sparkling, wholesome drinking water can be harder than you might expect. Drinking water may contain chlorine, lead, high levels of harmful bacteria, and other unwanted contaminants such as herbicides and pesticides. Frequently these produce unpleasant tastes and odors. Even bottled water can contain these same contaminants, and moreover it is very expensive. Most other filtration systems do not remove pathogenic bacteria and many remove the beneficial minerals from the water. Perhaps that's why Berkey Systems^® have long been recognized as the world's ultimate in water filtration. This simple, highly effective system was developed almost 200 years ago... yet it still produces virtually the finest, most healthful drinking water available. What makes the Big Berkey® system so revolutionary is that it removes pathogenic bacteria, reduces harmful or unwanted organic chemicals, while leaving in the healthful minerals that your body needs. The Big Berkey® system is so powerful, it is able to filter untreated raw pond, lake and river water.

The powerful Big Berkey®* Water Filter is ideal for your everyday use and...is the perfect camping and emergency filter.

*PROVEN HISTORY
The Big Berkey^® system's high quality and effectiveness has stood the test of time. First ordered by the Royal House in England, it's also been used by relief organizations such as Unicef, the Peace Corps, and Red Cross Societies Internationally. What's more, this same system has been used for over 150 years by missionaries, explorers and relief workers in over 140 countries around the world.

At the core of the Super Sterasyl™ ceramic filter element is the most basic of elements...EARTH. This is the same substance which artisans, first in Asia then in Europe, refined into exquisite porcelain and pottery of the Shoguns and Kings. This material is Diatomaceous Earth [D.E.], a fossil substance, made up of tiny silicon shells left by trillions of microscopic, one celled algae called diatoms that have inhabited the waters of the earth for the last 150 million years.

Diatoms have one property that sets them apart from other micro organisms. They weave microscopic shells which they use for the protection and locomotion. These shells are covered with a pattern of tiny holes so regular that even the slightest change in their design usually signifies a different species. As the diatoms died, their shells survived, slowly piling up in deposits at the bottom of geological lakes and lagoons. When these lakes dried up, what remained were huge deposits of "diatomaceous earth". Today there are over 1500 uses for Diatomaceous Earth, from abrasives for toothpaste, filtering agents for water and milk, heat insulators for kilns, to polishing agents in nail polishes, and many many more.

The latest designs of Super Sterasyl™ filter elements incorporate pure silver impregnated into a porous ceramic outer shell [80,000,000 pores] that can trap 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 element or in the ceramic's pores is 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 many times before the ceramic material is exhausted.

 A Closer Look Inside

KIESELGUHR CERAMIC - STAGE ONE
Super Sterasyl™ ceramic is made from Kieselguhr Diatomaceous Earth and fired at incredibly high temperatures. Over 80,000 overlapping pores make up each 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 are trapped on the outside of the element while the water passes through the ceramic wall to the inside of the element.

WHY Silver?
The entire ceramic wall is impregnated with pure silver. Silver has been long proven as a disinfectant which inhibits bacteriological colonization of the ceramic wall.

THE CORE - STAGE TWO
Inside the Ceramic shell is a post filter which is manufactured by using a treated granular carbon toform a tightly packed matrix. This post filter provides Chemical Reduction of chlorine, pesticides, solvents, etc.
