Plastic Fibers, also known as Microplastics, are small plastic pieces that can enter and contaminate drinking water. Scientists are studying the exact pathways that allow microplastics to enter into the drinking water supply. An extensive investigation on microplastics in water found that these analyses caught particles of more than 2.5 microns in size,” 2.5 microns […]

Do the Black Berkey® Elements remove GenX?
GenX is the trade name for a chemical that was introduced in 2010 as a “safer” replacement for a toxic contaminant known as PFOA (perfluorooctanoic acid, commonly called C8). Like its predecessor, GenX enables the production of common household products including non-stick pans, firefighting foam and water-repellent fabrics. Although few health studies are available on […]
Will Berkey® Systems remove Chromium from the water?
The short answer is Yes! Black Berkey® Elements have been tested to remove greater than 99.8% of Chromium 6. In fact, Both the Black Berkey® Elements and the Berkey Sport Bottle have laboratory testing, showing both Chromium and Chromium 6 reduction. It is important to note though, that not all forms of Chromium are undesirable. […]
How are the Black Berkey® Elements able to remove radiologicals for their full lifespan?
Many filter elements can show strong results that quickly decline. As such, we think it to be vitally important, with certain contaminants, that the reduction capability of our Black Berkey® Elements be tested over time. Such tests provide the rate of decline in efficiency and allow our customers a verification that the rate of decline […]
Black Berkey® Elements Test Results
Specially formulated to address 200+ typical contaminants found in tap water and other freshwater sources. Our unique Black Berkey® Elements are made from a proprietary blend of media, and are backed by independent third-party testing. The gold standard in gravity-fed water filtration, authentic Black Berkey® Elements are capable of greater contaminant reduction and a longer […]
Do your Black Berkey® 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. Test results have […]
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 […]
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: […]
Are the Black Berkey® 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 filtration elements. NSF Standard 42 (aesthetic effects) and Standard 53 (health effects) would specifically apply to our filtration elements. NSF Standard 42 covers systems “designed to reduce specific aesthetic or non-health-related […]
Will the Black Berkey® Elements remove kerosene?
Petroleum based products are some of the easiest to remove from water. The Black Berkey® Elements have been tested to reduce the following petroleum contaminants up to 99.9%: Gasoline Diesel Crude Oil Kerosene Mineral Spirits Refine Oil For complete lab results on the Black Berkey® Elements, click here However, please keep in mind that it […]
