The SodaStream Spare Gas Cylinder ensures you can keep enjoying sparkling water with your SodaStream sparkling water maker. Making up to 60 litres, each gas cylinder is highly cost-effective and helps to reduce your carbon footprint versus single-use plastic with it reducing the average household plastic bottle intake by 1,282 bottles and saves carrying heavy bottles from the shop.
