A device or person that cleans or removes impurities from something, often used for air or water.

Purifier → It is formed from "purus" (meaning pure) and "-ficare" (meaning to make). The word "purifier" refers to something that makes something else pure or clean.
Think of something that 'makes' ('-ficare') something 'pure' ('purus') — that's why a purifier is a device that cleans or purifies.
