The corona crisis has created unprecedented demand for Berkey systems and subsequently a shortage has arisen. The manufacturer is now working overtime to restore Berkey supply and we expect to have new Berkey stock within the forseeable future. Please check the site from time to time to see when the "out of stock" notices have been removed or 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.
