A tool that narrows down data or content displayed based on specific criteria (e.g., filtering emails by date or sender). Filters allow users to find relevant information more efficiently.

A filter helps sort through large amounts of data, like using a sieve to find specific grains of sand on a beach. In the context of data and searching, filters allow us to focus on exactly what we’re looking for, such as narrowing down search results or selecting relevant information. It’s important to understand because it helps people find what they need efficiently, but we also need to recognize that filters can sometimes exclude important information, much like only looking at part of a bigger picture.
