Big Berkey Gravity Water Filter All Sizes

Make an Informed Decision on the Quality of Your Drinking Water

Make an informed decision on something as important as the quality of your drinking water. Since water filtration is a complex science, we try to use familiar terms when possible so the explanation is easier to understand. Several methodologies are used to produce the Black Berkey® purification elements.

HEALTHY

Why are the Berkey® systems the benchmark in gravity fed water purification? It’s simple- they remove viruses, harmful pathogenic bacteria, cysts, parasites, unhealthy contaminants and impurities to below detectable levels, while leaving in the essential minerals your body needs. The result is the most healthful, delicious water available.

POWERFUL

Berkey® systems can easily purify ordinary tap water, yet are powerful enough to efficiently purify raw, untreated water from sources such as remote lakes and streams. In the event of natural disasters and emergencies when treated water may not be available, your Berkey® is essential.

ECONOMICAL

Berkey® systems are the most economical water purification system you can own. The long life of the Berkey®Purification elements allows you to enjoy purified water for about two cents per gallon. Compare that to the cost of bottled water!

CONVENIENT AND PORTABLE

Berkey® systems are easy to assemble and operate without tools, electricity, water pressure or plumbing. When traveling, or if space is limited, the top and bottom chambers of most of our systems nest within each other for easy transport.

PROVEN

Our independent lab results speak for themselves. Click here to view how the test results for our Black Berkey®elements exceed expectations for gravity purification.

MICROFILTRATION

The first line of defense is that Berkey® purification elements are composed of a proprietary formulation of more than six different media types, all constructed into a very compact matrix containing millions of microscopic pores. These pores are so small that they produce what we refer to as a “Tortuous Path” that pathogenic bacteria, cysts, parasites, herbicides, pesticides, organic solvents, VOC’s, detergents, cloudiness, silt, sediment and sedimentary minerals, foul tastes and odors must travel through. These paths are so small that these pollutants physically cannot pass through them and become trapped, eliminating them from your drinking water. This process is known as microfiltration.

ADSORPTION

Secondly, our media formulation uses unique adsorption and absorption properties. Adsorption works to create an ionic barrier similar to surface tension. This barrier is perfectly suited to the micro-porous water filter because it effectively allows the tiny pores to block water contaminants that are smaller than the pore size itself. This blocking process is how the Berkey® water filter is able to remove submicron viruses that other brands of water filters cannot, without the use of obnoxious chemicals like iodine or chlorine. Next, the heavy metals ions (mineral molecules) such as cadmium, chromium, copper, lead, mercury, aluminum, and other dangerous heavy metals are extracted from the water through an Ion exchange process where they are attracted to and transformed by electrically bonding to the media.

FLOW RATE

Finally, Berkey® systems are so effective at removing contaminants from water because of the extremely long “contact period”. Other filtration systems rely on water pressure that forces water molecules through the 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 structure of the Black Berkey®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 contaminants. 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 BlackBerkey® purification elements has been calculated to yield the greatest volume of removal of viruses, toxic chemicals, and bacteria.
