ELI5: Explain Like I'm 5

Clean room

A clean room is like your bedroom, but bigger and cleaner. Imagine that you want to clean your bedroom really well so you can play with your toys without any dust bothering you. You would clean the floor, the walls, the windows and your toys to make sure there is no dirt or germs. A clean room is a really clean place where people make things that need to be super clean, like medicine or computer chips for your tablet.

In a clean room, there are special machines that make sure the air is very, very clean. The people who work in the clean room wear special suits that cover their whole bodies and make them look like astronauts. These suits are called cleanroom suits and they keep the people from shedding any dirt or germs.

It is so important to keep the clean room clean because even a little bit of dirt or germ can ruin the things that are being made. That's why the people who work there have to be very careful and pay attention to all the rules. Just like when you clean your bedroom, you have to follow the rules for cleaning a clean room. You have to wear the right clothes, be careful not to touch anything and make sure you clean everything really well. That's how a clean room is kept clean and working well.
