People around the world have recognized clean, fresh drinking water as a key foundation of a healthy life and healthy
body. No amount of vitamins or supplements can substitute for the vital life-sustaining properties of nourishing, healthful
drinking water. Along with nutritious food and clean air, clean water is truly essential to life.
Systems are the world's most powerful and economical water purification systems, providing incredibly clean, pure water in both normal and hostile
environments. Berkey® systems can purify both treated water and untreated raw water from such sources as remote lakes,
streams, stagnant ponds, and water supplies in foreign countries with substandard regulations.
Filters and Purifiers. The
products noted are Berkey® Purifiers. The difference between filters and purifiers is defined by the EPA: A filter must be capable of “4
Log" contaminant reduction, and a purifier must be capable of a “7 Log" contaminant reduction. 4 Log (simple
filtration) means at least 99.99% of contaminants are removed, leaving no more than 1 part per ten thousand of the original
contaminant. This “filtration level" of reduction is sufficient for many conditions. The higher “purification”
reduction of 7 Log means that 99.99999% of contaminants are removed, leaving no more than 1 part per ten million of the original
contaminant (1000x the effectiveness of the “filter” specification.) Systems that achieve this "purifier
level" of performance provide ultra-pure water not only in normal conditions, but also in circumstances of extreme and
highly dangerous contamination.
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.
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 incredibly small that pathogenic bacteria are simply not able to pass through them.
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.
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.
The media within the filter element removes contaminants by a surface phenomenon known as "adsorption"
which results from the molecular attraction of substances to the surface of the media. As the bottle is pressed, the source
water is forced through the filter. The quality and volume of media used, determine the rate of adsorption. The flow rate
or time of exposure through the filter has been calculated to yield the greatest volume removal of toxic chemicals caused
by pollution from industry and agriculture. This exclusive filter element is impregnated with proprietary "absorbing"
media that promotes ionic "absorption" of pollutants within the micro-porous element, such as aluminum, cadmium,
chromium, copper, lead, mercury, and other dangerous heavy metals.The "Tortuous Path" structure of these pores gives
it its unique characteristics. The Sport Berkey® achieves 99.9% contaminant reduction. water that might contain extreme bacteriological
or viral contamination, it's recommended that two drops of plain chlorine or iodine be added to each refill before filtering.
This will kill minute pathogens such as viruses. The disinfectant will then be filtered from the water entirely, removing
its odor, color and taste and leaving only purified water. each set of two Black Berkey® elements produces
up to 6000 gallons of super pure water
Black Berkey® Purifier Elements are the world's most
powerful gravity filtering solution, certified to eliminate pathogenic bacteria to the EPA's "7 Log" purification
standard of 99.99999% reduction. Elements are easily cleanable with a Scotch Brite® pad under running water, and each
element will purify up to 3000 gallons of water (6000 gallons per set of two.) The Black Berkey® filter formulation has
been tested by State & EPA accredited laboratories to exceed EPA & ANSI/NSF (Std. 53) protocol. Click to see test
results from the University of Arizona, Spectrum Labs and the LSU Department of Toxicology and Environmental Science.
addition to their phenomenal reduction of pathogenic bacteria, cysts and parasites, the powerful Black Berkey® purification
elements also remove or reduce harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic
solvents, trihalomethanes, cloudiness, silt, sediment, nitrates, nitrites, heavy metals, foul tastes and odors. Yet they leave
in the water the healthful and beneficial minerals your body needs.
