What Are Oxygen Scrubbers?
Oxygen scrubbers are machines that clean air in tight spaces.
They take out bad gases, like carbon dioxide.
These devices are used in places where air can’t move freely.
You’ll find oxygen scrubbers in submarines, spaceships, and some buildings.
They help keep the air fresh when people can’t open windows.
Scrubbers come in different sizes.
Some are small and fit in a room.
Others are big and clean air for a whole building.
How Do Oxygen Scrubbers Work?
Oxygen scrubbers use special materials to clean the air.
These materials grab onto bad gases as air passes through.
One common type is a CO2 scrubber.
It uses a substance called soda lime.
When air goes through the scrubber, soda lime catches the CO2.
Some scrubbers use water to clean the air.
