Wondering about the efficiency of your Berkey® water filtration system? Do you want to know if the filtration is still efficient? There is a simple way, using red food coloring. Since it contains no minerals (which pass through the system), it will be "interpreted" as undesirable and will be retained by your filters. The red water at the beginning will be transparent at the end... In the video below, we show you how to perform this test and verify that your Berkey® system is fully operational.
If you have any difficulties in carrying out this operation or if you would like further explanations, you can contact us using our contact form.
