North America, particularly 1990-2010, fridges with a water dispenser and ice maker built in were/are pretty common. 3 of the 5 houses I lived in as a kid had one.

Filtered, colder-than-tap water, and effectively unlimited ice without having to screw around with ice cube trays. Some also provide heated water that's far cleaner than what comes out of a typical hot water tank, but that feature is rare in my experience.

They have a filter in the water inlet, and should be cleaned inside/out roughly every 6 months (that part is neglected more often than not).
