Must water filters be used and replaced?
Our house water is fine. We don't want to spend $40 once or twice a year to replace filters.
For model#: RF266AEWP/XAA:
Is the filter for the water dispenser only, or the ice cube maker only, or for both?
Since the fridge comes with a filter, we want to know if the filter MUST be used (i.e. can we remove the filter).
If it must be used (kept in place), MUST it be replaced periodically (how often)? -i.e. is it safe and functional to leave a "full" filter in place indefinitely?
