From the manufacturer New Bottle Design The iconic Aarke Water Bottle is now sleeker than ever, fitting perfectly with the Carbonator 3 and the Carbonator 2. The bottle’s bottom piece is now equipped with a newly engineered mechanism for increased durability. This also makes it possible to recycle bottles at the end of their lifetime. Being BPA-free and non-toxic, the PET Water Bottle is perfect not only for the kitchen countertop and the dinner table, but also to use it on the go. Tips & Tricks Made for Each Other Although one Aarke Bottle is included with the Carbonator 3, we recommend buying 2-3 extra bottles to conveniently serve and store sparkling water. To ensure your safety, please don’t use any other bottles, glass or plastic, with the Aarke Carbonator. Used with Pure Water Only To prepare for carbonation, fill the PET Water Bottle with fresh, cold drinking water up to the marked filling line. For optimal performance, carbonate pure water only with your Carbonator 3. Easily Cleaned Use clean water and a mild detergent to wash the Aarke Water Bottle. If a brush is used, make sure it is intended for cleaning PET Bottles and that it has no harsh bristles, which could leave scratches.
