Jura J9-J80-J85-J90-J95-Z7-Z9 Blue Water Filter Extension Rod
The water filter extension rod secures the water filter in the water tank. The wide end fits on top of the filter and the rod inserts into the top of the water tank. If you purchased a replacement water tank for the J5, J6, J7, Z5, Z6, Z7 models, then you need a blue filter and extension rod instead of the white. They are NOT interchangeable.
