Inverter compressor: Instead of switching hard on and off, the compressor modulates its speed to hold a steady internal temperature. That keeps food out of the temperature swings that shorten its life, and it means the fridge settles into a low, continuous hum rather than the loud cut-in you get from a fixed-speed unit — which matters in an apartment where the kitchen opens onto the living space.

Fresh Room quick-chill compartment: A covered shelf at the top of the fridge section runs colder than the main cabinet, so drinks, desserts and fish or meat you plan to cook the same day chill down faster and stay properly cold without being frozen.

Humidity-controlled vegetable case: The crisper has an adjustable vent, so you can hold high humidity for leafy greens and herbs that wilt in dry air, or drop it back for fruit that spoils when moisture is trapped around it. One drawer, two very different storage conditions.

Ag Clean filter: A silver-based filter treats the circulating air to cut odour transfer between foods and deactivate airborne bacteria — Panasonic's own testing puts the deactivation figure at 99.9%. It is the difference between opening the door to cold air and opening it to last night's curry.

Tempered glass shelving: The fridge shelves are tempered glass rather than wire, so spills sit on the shelf instead of running down onto whatever is below, and they wipe clean in seconds. Shelf heights are adjustable for tall bottles and stacked containers.

Door alarm: If a door is left ajar — the usual cause of a fridge running hard all night — the unit sounds an alert rather than quietly losing its cold and driving up the electricity bill.
