Berkey® Systems Secret


Black Berkey® Purification Elements are powerful water purifiers, they are not simple filters. They are powerful enough to purify both contaminated municipal tap water as well as untreated, questionable water from harsh sources such as lakes, rivers, streams and ponds.

Berkey® systems equipped with Black Berkey® Purification Elements remove greater than 99.999% of viruses and greater than 99.9999% of pathogenic bacteria, while also removing or dramatically reducing protozoa, trihalomethanes, inorganic minerals, heavy metals, pharmaceuticals, pesticides, VOCs, petroleum products, perfluorinated chemicals, rust, silt, sediment and radiologicals.

Two Black Berkey® Purification Elements in a Berkey® system will purify approximately 6,000 gallons of water before replacement is recommended.



The first line of defense is that the Berkey purification 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. These pores are so minute that they produce what we refer to as a torturous path that pathogenic bacteria, cysts, parasites, sediment and sedimentary minerals 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 is known as microfiltration.

Secondly our media formulation uses unique adsorption and absorbtion properties. Adsorption works to create an ionic barrier similar to surface tension. This barrier is perfectly suited to the micro-pourous 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) 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 not obtainable through conventional pressurized water filtration methods.

As you can see, the Berkey water purifier incorporates several different scientific methods to produce unmatched drinking water quality. We are able to do all of this and still maintain simplicity. All that you as a Berkey user are required to do is simply pour water into the unit. All of the processes mentioned above will continue to work for you behind the scenes for many years to come. This long filter life allows you to produce purified drinking water for 2 pennies a gallon.

The Black Berkey Purification Elements far surpass other water filters in filtration capability as evidenced by their extensive filtration specifications. These elements have a specialized purification process that is due to their unique structure. The element's filtration media is a combination of micro-pores, which trap harmful contaminants like bacteria, and revolutionary material with adsorption and ion exchange properties that essentially attract molecules and viruses to the media, preventing them from passing into your drinking water. A pair of Black Berkey Filters comes with every Berkey Water Filter System. Check out the Big Berkey Water Filter.

Maximum filtering capacity:

Many water filters on the market may claim to be a purifier but do not meet the performance specifications required for this classification. In order to be classified as a water purifier, a water treatment device must remove at least 99.9999% of pathogenic bacteria (known as a log 6 reduction in the water treatment industry) and reduce viruses by 99.99% (log 4 reduction). Our Berkey water filter systems can be classified as a water purifier because the elements actually remove 99.9999999% of pathogenic bacteria (log 9 reductions) and 99.999% of viruses which greatly exceeds the standards.

The Black Berkey filters have been tested by several EPA-accredited laboratories including the Department of Toxicology and Environmental Science at Louisiana University, Spectrum Labs, and the University of Phoenix. This extensive testing confirmed that the Black Berkey Purification Elements far exceed EPA and ANSI/NSF (Std. 53) protocol. Find out what makes Berkey a water purifier.
