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 to provide the purest, sparkling clean water possible...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. Water is often laced with chlorine, lead, high levels of harmful bacteria, and other unwanted chemicals and contaminants. Frequently these produce unpleasant tastes and odors. Even bottled water can contain these same contaminants, and moreover it is very expensive. Other filtration systems are inferior. Most do not remove pathogenic bacteria and many remove the beneficial minerals that your body needs.Perhaps that’s why Berkey® systems have long been recognized as the world’s ultimate in water purification. This simple, highly effective method of using gravity was developed almost 200 years ago... yet it still produces some of the finest, most healthful drinking water available.
How Berkey® Natural Water Purifiers Operate:To use, water is poured into the upper chamber. Gravity draws this water through the exclusive purification elements where contaminates are captured on and within theses micro-porous elements and are separated from the water. The purified water then collects in the lower chamber where it can be drawn through the spigot. What’s more, Berkey® elements are re-cleanable and can be used over and over again.
FEATURES AND HEALTHY BENEFITS* – Berkey® systems are far superior to other filtration systems because they remove harmful pathogenic bacteria, cysts and parasites as well as unhealthy chemical contaminates and impurities while leaving in the essential minerals your body needs. Berkey® systems produce virtually the most healthful, clean and delicious water available.*
CONVENIENT – Berkey® systems assemble in minutes without tools, electricity, water pressure, or plumbing. What’s more, they are simple to operate and maintain.*
ECONOMICAL – Berkey® systems are easily the most economical water purification system you can own. Their unique design allows you to easily remove and re-clean the purification elements over and over again.*
POWERFUL – Berkey® systems can easily purify ordinary tap water, yet are so powerful, they efficiently purify raw, untreated water from such sources as remote lakes and streams. What’s more, Berkey® systems are the ideal water purification systems to have on hand in the event of natural disasters such as blackouts, hurricanes, floods, earthquakes as well as local or national emergencies when treated tap water may not be available.*
FLEXIBLE – Berkey® systems are so convenient and easy to use, you can take them anywhere: on vacations, hunting and camping trips, college dorms and they are ideal systems for RVs and pleasure craft.*
ELEGANT – The elegant high-grade polished 304 stainless steel design makes Berkey® systems an attractive addition to any kitchen or home yet each system is both rugged and durable. *
PROVEN HISTORY – The same high quality and effectiveness of the gravity filtration process, that is utilized in Berkey® systems, has stood the test of time. Gravity filtration has been used by relief organizations such as UNICEF, the Peace Corps, Red Cross Societies Internationally, missionaries and relief workers in over 140 countries throughout the world. Have you ever wondered how Berkey® purification systems remove pathogenic bacteria, cysts and parasites while extracting chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness, silt, sediment, foul tastes and odors? Or, how Berkey® systems are able to reduce heavy metals such as cadmium, chromium, copper, lead, mercury, aluminum and other dangerous heavy metals, as well as nitrates and nitrites without removing the healthful and beneficial minerals that your body needs?
And finally, how is this system is able to remove food coloring from water without removing the beneficial minerals your body needs?
The unique Berkey® design 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 the elements remove 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 “absorbing” 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 filter elements at 60-90 PSI. These water molecules come into contact with the filter media for a mere fraction of a second. By comparison water molecules, passing through the “Tortuous Path” structure of the Black Berkey® purification elements, are drawn gently by gravity and stay in contact with the media for a long period of time. This allows the filter media to be more efficient in capturing contaminates. For example, if you were to hurl 100 steel ball bearings at a large magnet, some would stick but most would bounce off. However, if you were to walk over and gently place the ball bearings on the magnet most, if not all, would adhere to the magnet. Berkey® systems fully utilize this principle. This advanced technology was developed, refined, and proven through years of diligent, investigative research and testing performed by water purification specialists, researchers and engineers. The flow rate or time of exposure through the exclusive Black Berkey® purification elements has been calculated to yield the greatest volume removal of toxic chemicals and pathogenic bacteria found in nature and caused by pollution from industry and agriculture.
About Katadyn Water Filters
Technologies & Mechanical Water Treatment Katadyn Ceramic
Ceramic filters have a micro porous structure with impregnated silver which delays the growth of bacteria. The pore-size of Katadyn ceramic filters is 0.2 micron (0.0002 mm). Bacteria range in size from 0.2 to 5 micron and like protozoa (1 – 15 micron), are efficiently filtered out. Ceramic filters can be mechanically regenerated and the filter capacity is measurable.
Activated Carbon
Activated carbon is used for its ability to reduce harmful organic and inorganic substances in the water. It removes unpleasant tastes, odours, chlorine, pesticides (lindane, DDT) and trihalomethanes (THMs). These substances adhere to the large surface area of the activated carbon. Activated carbon granulate cannot be regenerated.
Glassfiber
Superfine glassfiber, within two supporting layers, forms a depth filter. Nominal pore size of 0.3 micron mechanically filters all bacteria and protozoa. The flexible glassfiber is pleated resulting in an extremely large surface area and a very high capacity to absorb dirt.
Reverse Osmosis
Reverse Osmosis, best known for its use in desalination, is the process of using high pressure to push a solution through a membrane that traps the solute (salt water) on one side and allows the pure solvent (fresh water) to be obtained on the other side.
Chemical water treatment
Chlorine Dioxide
As one of several 'oxides' of chlorine, it is a potent and useful oxidizing agent used in water treatment. It is effective in eliminating bacteria, viruses and cysts from water. Unlike the other halogens, chlorine dioxide tablets are effective against Cryptosporidium, even in dirty water.
Iodinated Resin
Effective in removing viruses and bacteria, iodinated resin, in conjuction with a cyst filter, is effective for water purification. Micro-organisms in the water are forced into contact with the tightly packed resin, which are bonded to iodine molecules. Iodinated resins leave less residual iodine in the water than iodine tablets. Without an activated carbon post-filtration medium, iodine leaves the water with an unpleasant taste. To eliminate the disadvantages of iodine, Katadyn only uses iodine with activated carbon post-filtration.
Silver
Silver ions are attracted to bacteria by polar adsorption. After penetrating the cell membrane, the ions damage the bacteria's DNA, thus preventing further multiplication. The bacteria's respiratory system is attacked and blocked, causing a chain reaction, and as a result the bacteria die.
Chlorine
Chlorine is the most commonly used substance for water treatment worldwide. It works quickly and has a broad range of applications. Chlorine, however, is not suitable for conservation and must be applied in the correct dosage.
Iodine
Iodine, like chlorine, is a halogen and has a similar spectrum of activity. While it is more pH-independent and more readily storable than chlorine, it is not quite as potent and therefore has a slightly longer contact time. Without an activated carbon post-filtration medium, iodine leaves the water with an unpleasant taste. To eliminate the disadvantages of iodine, Katadyn only uses iodine with activated carbon post-filtration.
