A new approach from Miele to keep your food fresh!Miele’s PerfectFresh Active freshness system creates the perfect storage conditions in your refrigerator. Every 90 minutes and whenever the door is opened, it sprays a fine water mist into the drawer. This creates a gentle layer of moisture on your food and keeps the air humidity perfect at all times – regardless of how full the refrigerator is. All you have to do is fill the small water container, and your Miele appliance takes care of the rest.
