What is an effective method to remove chlorine from water?

Boiling water is an effective method for removing chlorine, primarily because chlorine is a volatile compound that can evaporate when exposed to heat. When water is boiled, the chlorine present will typically vaporize into the air before the water starts to boil. This makes boiling an effective treatment for chlorine removal, especially if adequate boiling time is applied.

In contrast, while filtration can be effective for certain impurities, not all filters are designed specifically to remove chlorine. Chemical treatments often involve adding other substances to neutralize chlorine, but this does not remove it from the water. Reverse osmosis is a tighter process that can also reduce chlorine levels, but it may not be as straightforward or practical as merely boiling the water. Thus, boiling emerges as a simple and effective method, particularly in terms of accessibility and ease of implementation.
