Stainless steel is the classic look of Berkey® water systems. These durable, beautiful stainless icons of purity have produced safe water for millions of people around the globe for decades. Equipped with the new Black Berkey® purifying elements, Big Berkey® Stainless purifying systems function at the same incredible rate of efficiency as the Berkey Light® systems shown below. The wide range of available sizes makes a stainless system ideal for many Berkey® water filter users.

Unequalled Effectiveness: Berkey® purifiers using the Black Berkey® purification elements are proven to reduce pathogenic bacteria (including E. Coli, Klebsiella, Pseudomonas Aeruginosa, Giardia and Cryptosporidium) by 99.99999%. The Berkey Light® System has been tested with the highest pathogenic contamination levels that can be produced in a laboratory. When contamination levels exceed one billion pathogens per liter of water (10,000 times the density of contamination used in the standard test protocol for bacteriological removal) they're classified as "TNTC" (too numerous to count.) Under normal testing protocol, one pathogenic organism is tested at a time, each with a fresh purifying element. For this test, however, the laboratory was directed to combine three separate pathogenic TNTC cultures. Tested under this extreme contamination level, absolutely no pathogens were able to make it through the purification elements. The laboratory then incubated the water, and nothing grew. When the filtered water was viewed under an electron microscope not even in-viable (dead) microbes were detectable — nothing was present but pure H2O. Furthermore, contaminants reduced to below-detectable-limits include Trihalomethanes, Radon 222, and volatile organic compounds including Benzene, 2,4-D, Heptachlor, MTBE, Styrene, Tetrachloroethylene and Toulene, among many others.

Whether you need a home countertop water purifier or a portable camping water purifier, the Big Berkey® British Berkefeld® water filter and other models of British Berkefeld® water filters are the ideal solution for reliable, economical, ultra-pure water!

The Berkey® purification system removes pathogenic bacteria, cysts and parasites while extracting chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness, silt, sediment, foul tastes and odors. It reduces heavy metals such as cadmium, chromium, copper, lead, mercury, aluminum as well as nitrates and nitrites, without removing the beneficial minerals your body needs.

The unique design of Black Berkey® purifier elements combines the age-old process of micro-porous filtration coupled with modern state-of-the-art technology and the highest quality materials to bring you the finest water purification system available anywhere. The micro-pores within the self-sterilizing and re-cleanable Black Berkey® purification elements are so small that pathogenic bacteria are simply not able to pass through them.

The media within Black Berkey® elements removes contaminants by a surface phenomenon known as “adsorption” which results from the molecular attraction of substances to the surface of the media. The exclusive purification elements are also impregnated with proprietary media that promote ionic “absorption” of pollutants within the micro-porous elements. Another reason Berkey® systems are so effective in removing contaminants from water is the extremely long “contact period.” Other filtration systems rely on water pressure that forces water molecules through the filters at 60-90 PSI. In such systems, individual water molecules come in contact with the filter media for a mere fraction of a second. Water molecules passing through the revolutionary micro-pore structure of the Black Berkey® purification elements are drawn gently by gravity and stay in contact with the media for several minutes. This makes the Black Berkey® filter media much more efficient in capturing contaminants.

The dramatic superiority of Berkey® water purifiers is illustrated very graphically by its ability to remove food coloring from water. The Berkey® purifier's ability to achieve this level of contaminant separation shows demonstrates how strikingly superior Berkey® performance is compared to other purifiers. When bacteria are viewed under a powerful microscope, food coloring is often used as a contrast enhancer to make the bacteria easier to see. Even under magnification sufficient to show the detail in a single bacterium, food coloring still appears only as solid, uniform coloration. Yet the Berkey Light®, as shown on our main Berkey Light® Purifier page, actually mechanically removes the food coloring from the water — the Berkey® is the only filter system in the world that can do this. And, just as importantly, the beneficial minerals essential to maintain good health are left in the water for your body to use.

Berkey® Purifiers are available in several configurations. All Berkey® Systems using Black Berkey® purifying elements meet or exceed the EPA's stringent "Log 7" (99.99999%) contaminant reduction specification. Systems using Black Berkey® elements within transparent Lexan® housings are known as Berkey Light® Purifiers. Systems using Black Berkey® elements within stainless steel housings have the same purifying performance, and are known as Berkey® Stainless Purifiers. The same standards of water purification are achieved in either Lexan® (Berkey Light®) or Berkey® Stainless systems with Black Berkey® elements.
