Big Berkey Water Filters

The Black Berkey red food coloring test provides the opportunity to showcase the impressive purification power of the Black Berkey elements. Many water filter companies make claims to their high quality, but Berkey water filters go one step further by making their lab test results public and presenting demonstrations such as the red food coloring test. While helpful for new customers to see the Black Berkey filters in action, it is invaluable for the existing customer base since it can be used at anytime during the life of the filters to ensure they are working to design specifications. Whether the original black berkeys have been in operation for the past 3, 7, or 10 years, one can perform this test at anytime to see if it’s time for a replacement. We recommend customers place a cup underneath each filter as this will help isolate which filter is exhausted, and which is still purifying effectively.

With other water filters, the customer must assume their system is working to specifications or spend the time and money to perform water tests.  This time lapse video shows how simple the red food coloring test can be done after priming your Black Berkey filters.
