If you have a sparkling water tap or water bottling system installed then you will need to change your CO2 gas cylinder regularly, to keep your water sparking. These cylinders are easily changeable, please read our guide to learn how. The gas you require is Food Grade CO2, this is commonly known as Suregas and is available in multiple sizes. We recommend sizes SB or E as these can fit under your worktop, or B if storage size is not an issue.
Please note: this is specific to our Pura range. Order Suregas from BOC.
