The purification process that takes place inside a Black Berkey Purification Element is made possible by a complex compilation of more than a half a dozen proprietary blended media types that makes the formula unique and extremely effective, in the sectioned diagram below you may notice the glitter of some of these media types that make up the complex matrix that your water has contact with during the purification process. There are millions of fine micro pores as small as.01 micron that cysts, parasites, pathogens, coliform bacteria are unable to pass by. The very act of purification of the media both absorbs (to draw in) and adsorbs (to hold) contaminants. Heavy metals ions are captured by means of being electrically bonded to the media, the mineral molecules are attracted to then bonded together eliminating escape. Contact time with this media compilation is most important, the water is passed through in just seconds by gravity and not forced under pressure, this enables the media to work optimally to carry out the delicate and very complex process of water purification by identifying what is foreign and what is essential, the water molecule now has time to be examined but still achieving an acceptable flow rate.    

  • The Black Berkey™ Purification Elements have proven to be more powerful than any other gravity system on the market today by many independent studies.
  • No other purifier has the ability to be reverse flushed as demonstrated in the priming process due to the size of the micro pores, the element is efficient to remove bacteria and pathogens
  • Black Berkey™ Purification Elements give you the opportunity to prove their efficiency by carrying out the Red Food Colour Dye test, none comparable on the market today for such a test.
  • The powerful Black Berkey™ Purification Elements also remove or reduce viruses, pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, cloudiness, trihalomethanes, silt, sediment, heavy metals, foul tastes and odors, yet they leave in the healthful and beneficial minerals that your body needs, this is true purification in leaving behind the natural minerals.  

Below is a sectioned view of the Black Berkey™ Purification Element, this reveals the rigid construction of the Black Berkey™ that gives confidence for the endurance and investment that you have made to last the distance of 11,000 litres (3000 gallons) (4+ years) capacity of reliable purification.

During the process of sectioning this Black Berkey™ with a fine tooth metal saw, it was no easy effort and required much force to do so, it has given us the confidence that even if you were to drop and chip the Black Berkey™ that it would endure, we don't recommend you do that but the construction is definitely of rigid wall thickness and some of the media that is noticed  to shine inside confirms it's density plus with the convenience of the home lab red food dye test you will always know the integrity of the Black Berkey™ Purification Element 


The following youtube video released 26th October 2017 was in response to a manufacturing error back in 2011 found in the Black Berkey Elements that brought about design changes that have now strengthened the construction and durability that enables the Black Berkey Elements to last for years.
