Berkey purifier

Water filtration is a complex science, we try to use common terms when possible so the explanation is more understandable. We'll keep the techno-babble at a minimum.

Several well known methods are used to produce the Black Berkey® purification elements, for the Berkey Purifier. These methods are combined and blended to produce a unique filter process the likes of which the world has never seen. The elements are composed of a formulation of more than six different media types, all constructed into a very compact matrix containing millions of microscopic pores.  The pores are so minute that pathogenic bacteria, cysts, parasites, sediment and sedimentary minerals physically cannot pass through them. The media formulation uses unique adsorption and absorption properties to remove additional contaminates.  Next, heavy metals ions (mineral molecules) are extracted from the water through an Ion exchange process where they are attracted to and transformed by electrically bonding to the media. Finally, because of their gravity flow nature, water molecules can take several minutes to pass through the filter elements whereas these water molecules passing through other filtration systems pass through in only fractions of a second.  This longer contact time between the water molecules and the filter media, provides much greater removal rates of harmful water contaminates
