How do you purify impure water?

Impure water can be purified through several methods, including filtration, boiling, and chemical disinfection. Filtration removes physical contaminants using materials like sand or activated carbon. Boiling kills pathogens by heating water to a high temperature, while chemical disinfection, using substances like chlorine or iodine, effectively eliminates harmful microorganisms. For more comprehensive purification, a combination of these methods is often recommended.
