Want to store chilled and frozen groceries in the same unit? 50/50 fridge freezers are for you. These freestanding models from brands including Bosch, Hoover and Smeg provide ample room in both compartments. Fan-assisted designs use gentle currents of cold air to help food keep its flavour. Super-freeze styles rapidly drop their temperatures when the door is opened – which prevents older items from defrosting when new things are added.
