verb

purify

PYOOR-ih-fy/ˈpjʊrɪfaɪ/

To rid something of impurities.

This filter purifies drinking water by trapping dirt and debris.

A simple water-filtration setup visibly separates suspended dirt from water: muddy water above a filter, trapped brown sediment in the filter, and clear drops collecting in a clean glass vessel below.
Etymology

The roots literally mean “make pure.” In English, purify first described freeing something from spiritual pollution, then also came to mean removing extraneous material—the physical cleaning sense used today.
