Can I remove Chlorine naturally without APT PURE?Updated a month ago

Chlorine does dissipate by itself over 24 to 48 hours. The time taken depends on surface area of the water, and other factors such as flow.   

Boiling the water for an hour or so can speed up the process, but may not be a practical approach. 

Chloramine is much more stable and not does dissipate naturally. Activated carbon removes both Chlorine and Chloramine, but requires good contact time for complete removal.
