Filtering process

Coldstream tap water filters operate by diverting the cold water flow through a filter housing, passing through one of our ceramic filters and back out through a tap or faucet. The filtering process occurs as water is drawn from the tap and is on demand, so there is no storage of the filtered water anywhere in the system.

Coldstream manufacture a range of independently tested ceramic tap water filters to effectively remove contaminants from drinking water, leaving behind just the essential salts and electrolytes, which help give the water its taste.

To remove the contaminants we have used our experience and knowledge of the very latest filtration technologies, combined with the best materials available, to engineer a range of multi-layered ceramic filters that will guarantee the safety and quality of your drinking water.

QUALITY YOU CAN RELY ON

In comparison with other filters, independent Coldstream product test results show them to be the most effective at removing the widest range of contaminants found in water supplies worldwide and they outperform many reverse osmosis systems.

Coldstream filtration systems are cost-effective, require no power, filter 100% of water used and only leave behind essential salts and electrolytes.
