Coldstream Sentry Replacement Filter

Powerful Filters - The Coldstream filters are extremely powerful at filtering. They are even able to reduce fluoride (up to 97% - see test results). Doulton Super Sterasyl, Doulton ATC Super Sterasyl and Black Berkey Filters do not reduce fluoride on their own, so you have to add extra filters (the PF4's for the Doultons and the PF-2's for the Black Berkey Filters). This is a problem because they screw onto the end of the main filters and take up space in the filtered water chamber. They are also made of plastic so the plastic is then sitting in your filtered water, not nearly as good as Coldstream who have solved it through their more advanced filtering technology.

 

Fluoride Removal - the other very important aspect of the Coldstream filters is that they reduce fluoride without using Activated Alumina which exchanges fluorides with aluminium hydroxide. Coldstream use micro-ceramics to achieve this without migrating materials into the water through exchange making them far superior to older fluoride reduction technology.
