filterer

One who screens

A filterer is one who filters—someone or something that separates, strains, or screens.

The term applies to people who sort through information or materials, and to organisms like oysters and whales that feed by filtering water: Baleen whales are efficient filterers of krill.

The more common agent noun is filter itself.
