What are the different ways to purify water effectively and efficiently?

There are several effective and efficient ways to purify water, including boiling, filtration, chlorination, and distillation. Boiling water kills harmful bacteria and viruses, while filtration removes impurities through a physical barrier. Chlorination involves adding chlorine to water to kill germs, and distillation separates water from contaminants through evaporation and condensation. Each method has its own advantages and is used depending on the specific needs and circumstances.
