Below is some information that might be helpful, with respect to the seasonal Algae Blooms that have affected some water supplies in the past few years: “…Cyanobacterial cells range in size from 0.5-1 μm to 40 μm in diameter…” In other words, it’s a long skinny bacteria. Reference: http://huey.colorado.edu/cyanobacteria/about/cyanobacteria.php Internet research seems to indicate that […]

Do your Black Berkey® Purification Elements remove Glyphosate?
Glyphosate is a non-selective herbicide and pesticide. Glyphosate is primarily released into the environment via runoff water and predominately applied as a spray for agricultural purposes. This contaminant has recently become the topic of discussion because of its association with acute or chronic exposure leading to various potential health issues or concerns. The EPA has […]
Are your Black Berkey® Purification Elements and Berkey® systems Vegan and/or Kosher?
Technically, in order for anything to be defined as Vegan or Kosher, it must be consumable for ingestion. Our Black Berkey® elements and Berkey® systems are not consumable. Nonetheless, it is our understanding that these particular products may be considered to be both Vegan and Kosher, by answering the following questions: a. Is the product that […]
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 […]

Heavy Metal Test Results : Gravity Fed and Counter Top Systems
Water Filter Labs tested for the ability of the most common counter top and gravity fed filters to remove heavy metals such as lead, cadmium, arsenic and mercury as well as elements that have radioactive isotopes such as strontium, cesium, uranium, and aluminum reduction. Click the following link to view the test results: Water Filter […]
Are the Black Berkey® Purification Elements or Berkey PF-2™ and PF-4™ recyclable?
We don’t recommend the recycling of the Black Berkey® Purification Elements, PF-2s or PF-4s. The shells of the Berkey® PF-2™ and PF-4™ are made of Polypropylene, which is Recycle Code 5. Uses of Polypro (for short) include catsup bottles, yogurt containers, margarine tubs & medicine bottles. However, there is no recycle code for the Berkey PF™ elements. […]
Why do the log reduction levels differ for varying Berkey® element tests? Some laboratory results show testing to greater Log reduction (example: 99.9% vs. 99.99999%) than others.
“…The quantitation limit of an individual analytical procedure is the lowest amount of analyte in a sample which can be quantitatively determined with suitable precision and accuracy. The quantitation limit is a parameter of quantitative assays for low levels of compounds in sample matrices, and is used particularly for the determination of impurities and/or degradation products…” REFERENCE: […]
How should I store my Black Berkey® Purification Elements and how long is their shelf-life?
If you have used your elements: The method of storage depends upon the length of time that the Black Berkey® Purification Elements will not be used: If the filters will not be used between 4 to 15 days and you want to avoid the re-priming process, remove the filters from the system, place them into […]
Are the Black Berkey® Purification Elements NSF certified?
NSF certifications are not required but rather optional. In our opinion, NSF certifications are limited in their application with respect to our gravity fed purification elements. NSF Standard 42 (aesthetic effects) and Standard 53 (health effects) would specifically apply to our purification elements. NSF Standard 42 covers systems “designed to reduce specific aesthetic or non-health-related contaminants […]
