Enjoy Clean and Fresh Purified Water At All Times

Not only are you drinking purified water but also fresh water at all times with Sterra 7™ internal cleaning capabilities.

After the unfiltered water has gone through the 3 filters and 8 stages of filtration process, it will then pass through the internal flow path for sterilisation.

These cooling pipes are made from full stainless steel to prevent germs, rust, and contamination.

#1 Electrolytic Water Sterilisation — This pumps out any stagnant purified water that has not been used every 72 hours to ensure it only dispenses fresh and purified water. It also cleans up any mineral deposit build-up inside the tubing resulting in a clear flow path, and good water flow.

#2 UV Nozzle Sterilisation — This is another sterilisation that happens while water is being dispensed through the Sterra 7™ nozzle; the UV LED right on the nozzle automatically turns on, further cleaning and sterilising the water before it reaches your glass.
