How Gravity Water Filters Work
Gravity water filters use a simple two-chamber system. Untreated water is poured into the upper chamber, where gravity naturally pushes it through carbon filtration elements.
These filters trap bacteria, viruses, chlorine, heavy metals, and sediments without using electricity or water pressure. The purified water then collects safely in the lower chamber, ready for drinking.
