What is the Quooker CUBE? General

Alongside the boiling water-tank Quooker also developed a system for filtered chilled- and sparkling
water: the Quooker CUBE. This is an extra tank that is installed next to the boiling water tank in your kitchen cabinet. The CUBE contains a Hollow Fibre and an Active Carbon filter that purify the water. A CO₂ cylinder connected to the CUBE gives you 60 litres of chilled sparkling water.
