Knob for the lid of a stainless steel Berkey or Pure Filters water filter

All Berkey water filters and Pure Filters water filters come with a black lid knob as standard. If it is lost or damaged, this item can be bought separately as a replacement.

This knob screws onto the lid of the Berkey or Pure Filters water filter and lets you lift the lid off the upper chamber.

A BOROUX water filter does not need a knob, as this brand has a small tab on the side so the lid can be lifted off easily.
