Miele built-in fridge freezers are fully integrated and frost free. Each has the fridge above the freezer in a 70/30 split and sits behind a furniture door that matches your kitchen. The range runs from standard models for a single tall housing to much larger MasterCool appliances for bigger kitchens and households that shop in bulk. Every model here is also listed under Miele built-in frost free fridge freezers.

Size is the first decision. The standard models, including 54 cm and 56 cm wide versions, hold about 174 to 284 litres in the fridge and 70 to 98 litres in the freezer. MasterCool models are 762 mm or 914 mm wide, with up to 382 litres of fridge space and 197 litres of freezer space. You can choose left- or right-hinged doors, and the 914 mm size also comes as a French door version. They also have Push2open: you press the front to open the door, which suits a handleless kitchen.

Next, check how the door fits. Most models use a fixed hinge, which attaches the kitchen door directly to the appliance door so both open as one. A few use a sliding hinge, where the furniture door glides on a runner. Energy ratings range from B to E and noise levels from 29 dB to 39 dB, which is worth comparing in an open-plan room. Freshness features vary by model. DuplexCool gives the fridge and freezer separate cooling circuits, so food dries out less and odours don't pass between them. PerfectFresh Pro adds a fresh zone for fruit, vegetables, meat and dairy, and VarioRoom lets you rearrange the freezer to fit large dishes. Many models connect through Miele@home, and some add Holiday Mode and Sabbath Mode.

To narrow it down, measure your housing width first, because that decides between a standard model and MasterCool. Then match the hinge type to your kitchen door and weigh fridge space against the energy rating and noise level. If you don't need a fitted housing, Miele fridge freezers also covers Miele freestanding fridge freezers.
