Do Berkey systems have any other warranty?
Yes, the Black Berkey^® purification elements have a two-year prorated warranty calculated in six months intervals. Our guarantee is prorated similar to the guarantee on tire tread. In other words, if you have used the filters for six months, 75% of the guarantee still applies and so you can get a replacement set for 25% of the normal cost.

The systems themselves and their components have a six-month warrantee as stated below.
