2Three-second heating, seven settings

Choose ambient or 45, 55, 65, 75, 85 or 98 °C and water flows in three seconds. Volumes are 60, 90, 120, 200, 300 or 500 ml, and the touchscreen shows TDS and filter life.

3Seven-stage filtration and UV

Seven stages include a 0.0001 μm RO filter, with coconut-shell carbon to round off the taste. A UV lamp behind the tank sterilises, and a BPA-free Tritan pitcher can go straight in the fridge.
