Why does distillation produce pure liquids but filtration does not?

Distillation produces pure liquids because it separates components based on their different boiling points, allowing for the vaporization and subsequent condensation of the desired liquid, effectively removing impurities. In contrast, filtration merely separates solids from liquids or gases based on particle size, which may not remove dissolved substances or smaller contaminants. As a result, distillation yields a more purified product compared to filtration.
