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 remarkable.

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 unwanted substances found in nature and caused by pollution from industry and agriculture.
