Absolutely everything… that has a boiling point higher than water’s. It won’t do anything to remove alcohol, for instance. Or any other contamination that boils

  Yes, you're right in a pedantic way =). I trust that my city's tap water doesn't have alcohol in it. After all, I previously and many people still drink it without extra filtering, and it's safe enough to do so. Relatedly, the standard technique in alcohol distillation is to discard the head because it contains toxic methanol. https://youtu.be/a1IruS1bKN8?t=672 https://youtu.be/a1IruS1bKN8?t=672

    But alcohol isn't the only thing that has a boiling point lower than water.
