Black Berkey Purification Elements are the most powerful gravity filter elements currently available on the market. In fact, the Black Berkey water purification elements have been tested with more than 10,000 times the concentration of pathogens per liter than is required by standard test protocol. This concentration of pathogens is so extreme that the post filtered water would be expected to contain 100,000 or more pathogens per liter(99.99% reduction - the requirement for pathogenic removal). Incredibly the purification elements removed 100%. Absolutely no pathogens were cultured from the effluent or were able to be detected by an electron microscope, setting a new standard in water purification.
Black Berkey water filters are so effective, they can remove red food coloring from water without eliminating the beneficial minerals your body requires. To the best of our knowledge no other filtration element can duplicate this performance.
The powerful Black Berkey water filters also remove or reduce viruses, pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, cloudiness, trihalomethanes, silt, sediment, heavy metals, foul tastes and odors, yet they leave in the healthful and beneficial minerals that your body needs.
No need for expensive disposable filters. Black Berkey water filters are re-cleanable. When the flow rate decreases simply brush the Black Berkey water filters with a ScotchBrite pad under running water, reinstall and your system is again ready to purify water. Each durable and efficient filter will last for up to 11,350 liters (22,700 liters per set of two) and provide you with years of efficient water purification. For instance; If you were to use 38 liters per week, this is equivalent to 600 weeks. That's more than 11.5 years of clean water! What's even more unique is that the Black Berkey water filters are self-sterilizing.
Volatile Organic Compounds (VOCs)
Removed to below detectable limits
Pathogenic Bateria, Cysts and Parasites >99.9999%
|Heavy Metals - Reduced by up to 95%|
|Lead||kidney, nervous system damage|
|Mercury||kidney, nervous system disorders|
|Aluminum||respiratory, nervous system disorders|
|Chromium||liver, kidney, circulatory system disorders|
Also removes or reduces: rust, silt, sediments, detergents, cloudiness, iron, nitrates, organic solvents, foul taste and odors.
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 water 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 water filter 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 water 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 water filter systems fully utilize this principle.
All Berkey models come equipped with 2 Black Berkey water filters.*
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 water 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.
* Except the Go Berkey kit, which comes equipped with one Black Berkey element.
