The Baby Brezza Sterilizer Dryer Advanced is the most advanced way to automatically sterilize and dry bottles, pump parts and accessories. In one easy step, the machine automatically sterilizes, then dries 33% faster. It uses natural steam to effectively sterilize, then dries with 99% clean hot air thanks to the removable HEPA filter. The machine has the highest capacity of any sterilizer, holding up to 8 bottles, 2 full pump part sets and other accessories from any brand. The Sterilizer Dryer Advanced is modular so you can use it 4 different ways and you can use the LCD control panel to select from four functions (Sterilizer & Drier, Sterilizer Only, Dryer Only or Storage Rack). Products remain sterile inside for up to 24 hours until the lid is opened.
