How it works
Berkey BioFilm Drops™ introduce copper & silver ions to stored water where they deactivate and inhibit the formation of biofilm making water cleaner and fresher tasting. The drops are meant to be used in stored water because they must have ‘dwell’ time to deactivate biofilm.
4 drops treats one gallon of water.
