Unscreeened → It is formed from "un-" (meaning not) and "screened" (from the verb "screen" which comes from Old French *escren*, meaning to shield or protect). The word "unscreened" means not shielded or protected, indicating something that has not been filtered or covered.
Think of something that is 'not shielded' ('un-') — that's why 'unscreened' means it hasn't been protected or filtered.
