Most refrigerators here come with a built-in filter now at least to make ice. And often using a fridge filter or one that attaches to the sink tap is something anyone can do themselves, whereas an under the sink or whole-house system is something many people would hire someone to put in. So it’s probably a combination of convenience and cost.
We are on a well, so we have a whole-house filter system. But our fridge still came with a filter for its built-in tap.
That is a thing, but I know of exactly one person personally that has that. Most people here just have screw on filters that goes on their sink tap, or a fridge with a water dispenser, which already needs a water line for exactly the reason you guessed, ice cubes.
It is water from the filtered water dispenser built into the fridge.
Why not put the filter under the sink? Or is it always coupled with the refrigerator because, ice cubes?
