The SodaStream Spirit turns tap water into sparkling water in seconds. You can also infuse sparkling water with natural fruit, as a healthy alternative to sugary, fizzy drinks and customise the amount of bubbles you prefer in your water. This megapack includes two one-litre and a half-litre BPA-free PET carbonating bottles that have a lifespan of up to three years. The pack comes with a CO2 gas cylinder that makes up to 60 litres of sparkling water, saving you the effort, expense, waste and storage space involved with buying single-use bottles - up to thousands of bottles for the average household intake in a lifetime. The Spirit's design features include a snap-lock bottle system for quicker, easier and more intuitive use.
