Imagine water as a traveler on a journey. Along its path, it picks up various hitchhikers—dirt, chemicals, bacteria, and more—that can make it less than ideal for drinking. Water purification systems act as the guardians of this journey, ensuring that these unwanted companions are filtered out before reaching your glass.

First up, we have filtration systems. Picture a sieve or a strainer catching debris as water flows through. These systems use physical barriers like activated carbon, ceramic filters, or membranes with tiny pores to trap contaminants. It’s like having a bouncer at a club, only allowing the good stuff—pure water—to pass through while kicking out the troublemakers.
