Zeolite is an energy-efficient, fast drying technique that even dries plastic containers. All Bosch dishwashers with a C energy label use this technology. At the bottom of the dishwasher, there are zeolite granules that trap moisture and convert it into heat. The mineral regenerates itself after every program and you don't have to replace it. Only Bosch and Siemens dishwashers use Zeolite for drying your dishes. On this page, you can find all Bosch dishwashers with the Zeolith Drying system.
