The Berkey manufacturer has filed a lawsuit against the EPA seeking to stop it's unjustified persecution of Berkey Water Filters based on the EPA’s decision this year to treat Berkey Water Filters as though they are pesticides, rather than water filters. The EPA has already ordered the closure of Berkey's largest warehouse. Please see our blog post for the details.

Lab Test Results

The Black Berkey filters have been tested through the years by various independent EPA approved laboratories. NMCL, the manufacturer, publishes the results of these drinking water tests on the Black Berkey filters to provide people with the information they need to make an informed decision when purchasing a water filter. Below you will find links to testing done upon the Black Berkey filters for the elimination of among other things: heavy metals, bacteriological pathogens, radioactive isotypes, pharmaceuticals, perfluorinated chemicals etc. If you have any questions or concerns related to the results of these drinking water tests please don't hesitate to contact us at
