refilling my water bottles, of which I drink at least 5/day,

So isn't the water at room temperature by the time you drink it?

I am guessing she has an insulated bottle and drinks it before it gets
warm.

what does the filter in the fridge filter for and, if necessary,
wouldn't it be easier and cheaper to get one for the kitchen sink?

Probably hence my R/O. The fridges tap off of that at my house.
