Miele built in fridges are fully integrated. They sit behind a door panel that matches your kitchen units, so the fridge disappears into the run of cupboards. Nearly all are larder fridges, which give the whole cabinet to chilled food, and you can see them together under Miele built in larder fridges. The exception is a built-under model with a small four-star ice box, which suits a kitchen that needs a little frozen storage but has no room for a separate freezer. Capacities run from about 92 litres under the worktop to 567 litres in a full-height MasterCool fridge.

Start with your housing height. Miele tall built in fridges fill a full-height space, and most hold around 294 to 309 litres. The MasterCool models go up to 463 and 567 litres. Both have an Active AirClean filter to remove odours and sturdy MaxLoad Hinges, and you choose left- or right-hand hinging when you order. Built-under options, including Miele undercounter built in fridges, hold roughly 119 to 136 litres. Some have a normal door. Others have a pull-out drawer front, so you look down into the contents instead of reaching to the back of a shelf. Most doors can be swapped to the other side, but a few cannot, and a couple of simpler models need manual defrosting.

Freshness features differ more than size does. DynaCool, found on many models, uses a fan to move cold air around so the top shelf stays as cool as the bottom drawer. PerfectFresh Pro adds a separate humidity-controlled compartment. On the higher models, PerfectFresh Active sprays a fine mist at intervals to keep the air moist around fruit and vegetables so they don't dry out, and one of these also has ActiveDoor, which opens the door hands-free. SoftClose doors and Miele@home app connection appear on most models. Energy ratings run from B to E, and noise levels from 29 to 40 dB.

Measure your housing first. Then decide whether you want a normal door, a drawer front or a little freezer space, and how much a humidity-controlled produce zone matters to you. To weigh these against other installation types, look at all Miele fridges.
