How long can I keep and consume the water filtered by my Berkey® purifier?
We recommend replacing your filtered water with your Berkey® system after three days if it has not been used. If the water is in a cold environment, the time can be extended to one week. This is a precautionary principle. The reason is that when you filter your water, the chemicals that inhibit the growth of bacteria are removed. In very humid environments, bacterial growth can occur more quickly.
