Replacement PET bottles for the AARKE II and III sparkling water makers. Insert the PET bottle into your sparkling water maker and enjoy carbonated drinking water at the push of a button. The bottle is made from BPA-free PET plastic and is encased with a stainless steel base that protects the bottle and its contents from potential impacts. To make the bottle suitable for on-the-go use, it comes with a matching stainless steel lid. Additional information, such as the fill level indicator at 0.8 L, is conveniently noted on the bottle.
