We achieve this through our unsurpassed technical understanding of filtration techniques and material performance, our comprehensive system and filter testing and manufacturing quality assurance and using our unique high performance ceramics made using our own hi tech manufacturing processes.
Coldstream have recently entered the market for portable gravity water filters with this fantastic new product, the Coldstream Sentry Gravity Water Filter System. They have taken all the product flaws with other leading products on the market and solved them through their innovative approach. Here is a summary of what makes them different and better:
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.
