Berkey Biofilm Drops Extend Shelf Life of Stored Water—for Use with Long-Term Water Storage Containers, Ideal for Emergency Preparedness

One bottle of Berkey Biofilm Drops treats up to 330 gallons of clean water and extends its shelf life up to 5 years, eliminating the need to rotate your stored water every 6 months.

Berkey Biofilm Drops are not intended to kill biological contaminants or purify water. Rather, they are scientifically engineered for use in defense against the potential growth and buildup of biofilms, which protect pathogenic microbes from disinfection by creating a slime layer that can spread inside water storage containers.

Simply add drops to potable water to extend the shelf life of stored water in long-term water storage tanks, jugs, and drums. Berkey Biofilm Drops can also help maintain fresher water in RV and boat drinking water tanks.

By helping inhibit potential biofilm growth, Berkey Biofilm Drops can help extend the life of Black Berkey Elements and other gravity-fed water filters such ceramic and carbon-block filters and may extend the time needed between filter and system cleanings.

Easy-to-use kit includes Berkey Biofilm Drops, copper testing solution and instructions.
