What can you do with chlorinated H2o other than using a filter to get rid of the chlorine smell and taste?!
If it's for a fish tank or something, just leave it in a glass container on the counter for 3 or 4 days (longer than for drinking water, because fish are more sensitive to chlorine than humans are).
Answers: For drinking water: put it in a container (preferably glass) and put it in the refrigerator for a day or two. The chlorine smell and taste should be diminished, if not gone. Actually, you don't have to refrigerate it, and the chlorine probably dissipates faster at room temperature, but chilling it dulls any remaining unpleasant flavors more effectively.

An easy way to get rid of the chlorine taste and smell is to let water sit in a glass for a few minutes. Then, put the water in a covered container and chill it in the refrigerator. Cold water tastes and smells better than water at room temperature.
