Knowledge about chlorine

Water stations use chlorine to kill bacteria and sanitize germs in water to ensure a low level of microorganisms reach consumers.


However, chlorine can be harmful to humans – studies show that consuming an excess amount of chlorine increases the chance of getting cancer, as well as skin and hair problems. Chlorine concentration is not stable for all the time, so checking its level regularly can be important.
