How Do Filters Work?
Filters work by picking or blocking things. They let good parts pass through. They stop bad parts from passing.
Example: Water Filter
A water filter has tiny holes. Water can pass through these holes. Dirt and germs are too big. So, they stay behind. Clean water comes out the other side.
Example: Email Filter
Email filters check words in a message. If the message has bad words or looks like spam, the filter moves it. It keeps your inbox safe.
Example: Search Filter
Search filters look at your choices. If you want red shoes, the filter shows only red shoes. It hides all other shoes.
