SOMETHING IMPORTANT
How does the Berkey® Systems work?
Berkey® systems are designed to work without the need for electricity or plumbing. They are “off-the-grid” water purifiers and are gravity fed
Benefits of Berkey® Purification Systems
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.
SOMETHING IMPORTANT
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.
SOMETHING IMPORTANT
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!

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 Black Berkey® purification elements has been calculated to yield the greatest volume of removal of viruses, toxic chemicals, and bacteria.

HOW IT WORKS
Each Berkey® system consists of an upper and lower chamber. Water is poured into the top chamber, where gravity pushes it into the filters. The purified water collects in the lower chamber, where it can be dispensed through a spigot.
CHOOSE YOUR SYSTEM
Berkey® offers six different sized stainless steel systems and one Berkey® Light system constructed of non-BPA copolyester. When choosing a system, please consider the following: how many people (and pets) will be drinking the water, how much space you have in the kitchen or area where it will be used, and whether the system will be used for sustained or emergency use. Please keep in mind that the larger the system, the less often it will need to be filled.
CHOOSE YOUR PRIMARY FILTERS
We carry two types of filters; the Black Berkey™ Purification elements and the white Super Sterasyl ceramic filters. All of the Berkey®systems come standard with two Black Berkey™ purification elements or two white Super Sterasyl filters. The Black Berkey™ elements or ceramic filters are placed in the top chamber of the Berkey system. If you add additional elements or filters to your system, this will increase the flow rate of the water from the top to the bottom chamber. Please note that the purification quality of the water does not change by adding additional elements/filters, but it will increase the speed and volume of water that can be purified. Flow rates are calculated with the upper chamber full to the top. The flow rate decreases as water level declines. As it is impractical to keep the upper chamber completely full at all times, the flow rates are in practice less than the stated optimal rate.
CHOOSE YOUR POST FILTERS
If you want to reduce fluoride in your water, you will need to use post filters that work in conjunction with the filters in your system. We have two types, the PF-2™, which are used in conjunction with the Black Berkey™ purification elements, and the PF-4™ filters that are used in conjunction with our ceramic filters.

It is certainly no secret that the quality of mains and tap water in the NZ varies greatly and often contains high levels of chemicals and other contaminants. These can range from the obvious, such as chlorine and sodium, to the slightly more alarming: pesticides, nitrates and heavy metals. 
One recent story in the papers revealed that even the female hormone oestrogen – the active ingredient present most contraceptive pills – could potentially be found in drinking water. This is due to the fact that sewage treatment may not remove all traces of the hormone, which in turn can have negative consequences for male fertility.
When faced with such concerns and uncertainties more and more people are investing in their own personal water filters and water purification systems. This is particularly true of those who live in urban areas and are thus exposed to much higher levels of potential pollutants than normal. In terms of quality and reputation, you’d need to swim an ocean to find products with as clean and clear a result as Berkey.
Certainly the exterior is appealing, with the trademark black and silver giving these water filters a certain prestige and visual vivacity; however, as we have already seen with tap water, it’s what’s inside that counts.
Berkey water filters use a variety of techniques to ensure maximum filtration effectiveness. The terminology may be complex but the science is very real. Firstly, water is subjected to micro-filtration, whereby it is passed through a complex matrix of minuscule pores designed to remove a massive array of impurities such as silt, bacteria, organic solvents and pesticides.
Next is the absorption process. This removes heavy metal impurities at an ionic level, as well as expelling sub-micron viruses. Berkey filters are one of the very few that do this effectively without the use of chemical agents, a technique which rather defeats the point of water purification.
Finally we have flow rate. While other filters only have minimal contact with the water itself – often lasting mere seconds – Berkey filters process the water more fully, thus yielding a greater volume of removed impurities, both chemical and biological.
These techniques are the result of years of research into water filtration and purification, with the sleek casing being an additional bonus. So if you are looking for a water purifier that does the maximum rather than the minimum, look to Berkey. .
