What is ORP? ORP stands for Oxidation Reduction Potential or Redox. It is the activity or strength of oxidizers and reducers in relation to their concentration in water. It is not (like pH) a measurement of concentration, rather of activity level. Different meters are available to measure the ORP in your water. ORP is measured […]

Why do your instructions say : “Do not allow filter to freeze?”
We strongly advise against freezing your elements as a general rule of caution. We also advise against storing the elements (even unused) in sub-freezing climates. The concern with freezing the elements is that any cold or freezing water will expand inside in the element, thereby increasing the pore size and ruining the element. Whether the […]
How do I collect a water sample?
When testing a water sample, we recommend using this standard testing protocol
Do your filters take out plastic from the water?
There are various plastic materials that can be leeched into water and the most common are BPA ( Bisphenol A) and 1,1-Dichloroethane (11-DCA). The Black Berkey elements have been tested to remove both of these plastic materials. Please refer to our lab testing results by clicking here
What happens if I use my Black Berkey® Elements after 3,000 gallons?
We determine the typical lifespan of the Black Berkey® Elements by their ability to reduce heavy metals. The breakthrough of heavy minerals can occur at about 3,000 gallons. Heavy metals can leach through beyond 3,000 gallons. However, the elements can be used beyond that point because other reductions continue well beyond 3,000 gallons.
Comparison of Berkey® Purification to Reverse Osmosis and Distillation
Healthfulness of Reverse Osmosis and Distillation Based on current research, most health experts are no longer recommending drinking Reverse Osmosis or Distilled water on a long-term basis because these methods strip out all of the beneficial minerals from the water, making the water an acidic “hypotonic” solution. A chemist will tell you that when a […]
Since the filter has pores fine enough to remove viruses, does it get clogged frequently?
The proprietary filter formulation used in Black Berkey® Purification Elements makes up for the incredibly small pore size by utilizing an exponentially greater number of micro pores in each purification element than that found in other filter elements. This is the reason Black Berkey® Purification Elements produce approximately 8 times more water per hour than other elements. While some of […]
How does the filter element in the Berkey® system deal with viruses?
The micro fine pores are so small that they prevent micro fine particulate such as bacteria, viruses and even food coloring particulate from passing through the tortuous path that water is able to pass through. These contaminates are trapped in the micro fine pores while the much smaller H2O molecules are not. This method separates […]
Do the Black Berkey® Purification Elements remove Chloramine?
Yes, our Black Berkey Purification Elements do remove Chloramine. Please click here to see the attached test results.
Do your Black Berkey® elements and Super Sterasyl™ Elements reduce fluoride in the water?
No, in order to reduce fluoride in your water, you will still need to use post filters that work in conjunction with the filters in your system. We have two types of post filters: the Berkey PF-2™ Elements which are used in conjunction with the Black Berkey® purification elements, and the Berkey PF-4™ Elements that are […]
