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.

Alpha Radioactive Isotope Removal Tests

The Berkey manufacturer, NMCL, has recently released the lab test results for the removal of radioactive isotopes. The first round of alpha radiological testing was done for the following radioactive isotopes:

Americium-241
Mendelevium-258
Neptunium-237
Plutonium-238 and -239
Polonium-210
Protactinium-231
Radium-226 and -228
Thorium-232
Uranium-235 and -238

The Black Berkey filters were found to remove the radioactive contaminants listed above to a level of 98.7%.
