I love, love, love my travel berkey!! Berkey is the best by far and I have done lots of research on water filters. The people at water for life are so friendly and helpful 🙂
The Berkey Secret
Have you ever wondered how Berkey purification systems remove cysts, parasites, fungi, bacteria, and even viruses while extracting harmful chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness, silt, sediment, foul tastes and odours? Or, how Berkey systems are able to reduce heavy metals such as cadmium, chromium, copper, lead, mercury, aluminum and other dangerous heavy metals without removing the healthful and beneficial minerals that 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 cleanable Black Berkey purification elements are so small that even viruses 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.
Why is the Berkey system so effective in removing contaminants from water, compared with other systems? The secret lies in the extremely long “contact period”. Other filtration systems rely on high 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. In contrast, 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 much longer period of time. This allows the filter media to be far more efficient in capturing contaminates. The following example may help you to visualise this process: 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. The Berkey system is based on 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 exclusive Black Berkey purification elements have been designed to achieve the flow rate or time of exposure that yields the greatest volume removal of viruses, toxic chemicals and bacteria found in nature and caused by pollution from industry and agriculture.
