The Miele KFN 7774 B is a built-in fridge freezer for a 178 cm niche, hidden behind a furniture door, with 245 L of storage. It suits an open-plan home that wants a very quiet fridge freezer with a humidified fresh-food zone. PerfectFresh Active uses active humidification, which Miele says keeps food fresh 5x longer.

Cooling and storage

The fridge section holds 175 L, including a 71 L PerfectFresh zone, and the 4-star freezer holds 70 L. DynaCool keeps the temperature even throughout the fridge, while DuplexCool runs separate cooling circuits for fridge and freezer. NoFrost means no defrosting, and VarioRoom lets you rearrange the freezer for bulky food.

• 4 shelves, including a split FlexiBoard, with 2 lit by FlexiLight 2.0
• 2 crisper drawers and 2 door shelves, with racks for tins and bottles
• 3 freezer drawers, 2 of them on runners
• CleanSteel dry back wall and ComfortClean parts

Controls and everyday use

FreshTouch controls set the fridge and freezer independently, and you can switch the fridge off on its own. SuperCool and SuperFreeze bring temperatures down after a shop, and Holiday, Party and Sabbath modes adapt it to your routine. SoftClose and SelfClose help the doors shut gently. Miele@home adds push notifications, cooling tips and remote updates. It runs at 29 dB(A) and uses 131.77 kWh a year at energy class B.
