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 […]
The length of storage depends on the treatment of the water. When using the Berkey Biofilm Drops, water can be stored for up to 5 years. It is recommended for long term storage to use 16 drops (1/2 tablespoon) of chlorinated bleach per gallon of water. Both treatments will inhibit bacteria growth. Once you are […]
I heard that it is recommended to replace my Berkey water after three days. Is this true if it is refrigerated?
We do recommend replacing your Berkey water after three days. If the water is in a cold environment, the length can be extended to a week. This is a conservative estimate for caution. The reason for this is because when you filter your water, the chemicals that inhibit bacteria growth are removed. In more humid […]
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 […]
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 […]

Coliform bacteria are not pathogenic (disease causing) organisms but are a natural part of the microbiology of the intestinal tract of warm-blooded mammals, including man. Total coliform bacteria are a collection of relatively harmless microorganisms. Coliform bacteria can be found virtually everywhere – in soil, on skin, on animals, insects, in lakes and rivers, etc. […]
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: […]
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 […]
