>Berkey and its manufacturing arms agreed to a request from the EPA for Berkey filtration products to be identified as “treated devices” (which is a different classification than a pesticide or a pesticide device), because they incorporate silver (a registered pesticide) in their filter media (a common additive in water filters which does not leach into the water) that protects the filter from biological grow through
