Berkey® Biofilm Drops

Protect Your Water Storage from Biofilm-Related Bacteria

Berkey Biofilm Drops™ is a scientifically engineered, patented Copper-Silver Ion solution designed to defend against biofilm-related bacteria in ceramic water filters, carbon/charcoal filters, and water storage containers. Specially formulated for harvested rainwater containers, long-term water storage, and emergency preparedness, it works best with Black Berkey® Elements but is compatible with any type of filter media. A few drops extend the shelf life of stored water up to 5 years, eliminate the need to rotate stored water every six months, and keep your water fresh-tasting and odour-free. It also extends the time between element cleanings, making it an easy, low-maintenance addition to your water preparedness routine.

Simple and easy to use — just add the recommended amount to your water storage container or filter system. No more worrying about stale or contaminated stored water.
