Make your water better with a natural swirling motion. The swirling motion increases gas transfer between the air and the water. This process accelerates the release of volatile compounds (such as chlorine and THMs) as well as balances the dissolved oxygen levels, resulting in sweeter, more “silky” water. Hand-made porcelain base coupled with innovative technology Solid-state load cells in the base sense the presence of the carafe and automatically begin the swirling motion according to the amount of water in the carafe for a perfect, hassle-free vortex. The pitcher is hand – blown from grade A borosilicate tempered glass. This 1.5-liter pitcher is lightweight, crystal clear, and durable (dishwasher safe). The water-drop shape keeps all the water in constant motion.
