The corona crisis has created unprecedented demand for Berkey systems and subsequently a shortage has arisen. The manufacturer is working overtime to restore Berkey supply and we expect to have new Berkey stock before the end of August. If you would like to be alerted please send us an email specifying the Berkey model you want and we will notify you when it is back in stock. In the meantime the Black Berkey filters and PF-2 filters are available. Thank you for your understanding and we look forward to serving you in the near future.
