About Berkey Water Filter Systems
Berkey Water Filters - Actually Water Purifiers
Berkey water filters are so powerful they are actually considered to be water purifiers. The Berkey system uses the Black Berkey water filter. It combines the age-old process of micro-porous filtration used by nature, partnered with modern state-of-the-art technology and the highest quality materials to bring you the finest water filtration system available anywhere.
The Berkey water purification system removes pathogenic bacteria, cysts and parasites as well as 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 micro-pores within the self-sterilizing and re-cleanable Black Berkey purification elements are so incredibly small that pathogenic bacteria are simply not able to pass through them.
The proprietary media in the 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.
Above is a picture of the Berkey Light with the upper container filled with water containing red food coloring. The lower container is filling up with bright, clear, safe to drink water. The Black Berkey filters are so efficient that they can remove the food coloring from the water. The Berkey purifier''s ability to remove this level of contamination is evidence of how powerful the Black Berkey is compared to other purifiers. The powerful Black Berkey filters can mechanically remove 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.
The Black Berkey® filter formulation has been tested by State & EPA accredited laboratories to exceed EPA & ANSI/NSF (Std. 53) protocol. The test results come from the University of Arizona, Spectrum Labs and the LSU Department of Toxicology and Environmental Science.
Berkey Filters Use Fresh Water From Any Source
Berkey water filter systems are capable of purifying both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where water quality regulations may be substandard at best. It is perfect for everyday use and a must in hostile environments where electricity, water pressure or treated water may not be available.
Berkey's are easy to use. The upper chamber of the unit is filled with water. Gravity then draws this water through the filters, where it collects in the lower chamber.
The portable two piece housing is lightweight and compact and only takes minutes to assemble. Constructed of high grade, polished stainless steel, it is hygienic, durable and easy to clean.
Berkey® Natural Purification Systems are the ultimate in water purification and the ideal personal protection and traveling companions. Used worldwide for normal, hostile and emergency environments the Berkey will consistantly provide the pure, sparkling clean water.
BERKEYS REMOVE WATER-BORNE PATHOGENS BY 99.99999%
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 Black Berkey filters have been tested with contamination levels exceeding one billion pathogens per liter of water (10,000 times the density of contamination used in the standard test protocol for bacteriological removal). 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 no microbes were detectable.
BERKEY FILTERS REMOVE TOXIC CONTAMINANTS
The following contaminants are reduced to below detectable limits: Trihalomethanes, Radon 222, and volatile organic compounds including Benzene, 2,4-D, Heptachlor, MTBE, Styrene, Tetrachloroethylene and Toulene, and many others.
BERKE'S FIVE UNIQUE FEATURES
BERKEYS ARE SELF-STERILIZINGThe Black Berkey filter medium immediately kills the captured biological contaminants. You never need to worry that a zoo of biological contaminants is growing on or in the filter.
BERKEYS ARE SELF-REGULATINGAs the capacity of the filter is reached, the flow will diminish, letting you know it is time to simply clean it. Unlike most flow-through systems which keep forcing water through the filter whether it is working or not, this water filter system will never allow contamination to reach the clean water reservoir.
BERKEYS ARE NON-ELECTRICThese units utilize the power of gravity to push water through the filter. Everyday, during a power outage or in an emergency you can depend on your Berkey Filter to efficiently and inexpensively provide you with a source of safe, clean drinking water.
BERKEYS ARE EASY TO USETo use, simply pour water into the upper chamber. Gravity draws this water through the filter elements where contaminants are captured. The purified water collects in the lower chamber where it is drawn off through the spigot.
BERKEYS ARE POWERFUL PURIFIERSThe purification elements in these units are MORE POWERFUL than any other gravity filter available. All the health benefits of drinking an adequate amount of water are yours without the cost and inconvenience.

"I purchased the ''Big Berky'' water purifier unit in the fall of 1999. Shortly after moving to Spokane, I began noticing this water filter in the homes of friends. I began asking questions about it. The information I was given was all positive, so I figured the best word of mouth advertising is your friends because friends won''t steer you wrong. I called and ordered the nice stainless unit. I absolutely love this unit and wouldn''t be without it. Also, another friend who has a private well, purchased the ''Big Berky'' and also loves the way her water tastes. Prior to that, she wouldn''t drink her water as it was heavy in iron."

"Just a note to tell you how much the Berkey water filter system meant to our Honduran Medical/Educational Teams. We have been going to Honduras for 6 years, and we usually have 10% to 50% of our team incapacitated by "Montezuma''s Revenge" by the time the mission is over. Since we started taking your Berkey we have had no one, repeat no one, sick with the GI (Gastro-Intestinal) Bug. I also want to personally thank you for your wonderful follow up and service.
