Berkey™ filter set

ABSORPTION

After that, our media possess unique adsorption and absorption properties. Adsorption works by creating an ionic barrier similar to surface tension . This kind of barrier goes well with the microporous water filter because it effectively allows the tiny pores to be removed and impurities smaller than the same pores. It is this blocking process that allows the Berkey water filter to remove submicron viruses that other brands of water filters cannot remove without the use of harsh chemicals such as iodine or chlorine. Furthermore, heavy metal ions (mineral molecules) such as cadmium, chromium, copper, lead, mercury, aluminum and other dangerous heavy metals are removed from water by the process of ion exchange, whereby the medium attracts them and changes them by electrical binding to the medium.

FLOW SPEED

Finally, Berkey^® systems are so effective in removing contaminants from water due to extremely long “time contact”. Other filtration systems rely on water pressure that forces water molecules through the articles at a pressure of 4-6 bar. Thus, the water molecules will be in contact with the media filter for only a fraction of a second. Let's compare with Berkey^® devices where the molecules passing through the structure of the Black Berkey^® article are slightly attracted by gravity and are in contact with the media of the article for a longer time. This alone makes the medium of the Berkey^® article more effective in capturing impurities. This technology has been developed, refined and proven over years of careful research and development and testing by water purification experts, researchers and engineers. The flow and time of exposure of the water in the Black Berkey^® media to the members have been calculated so as to achieve the greatest degree of elimination of potential contamination from the water you drink, regardless of the source of that water.
