Dust mask

A dust mask is a special kind of mask that you wear over your nose and mouth to keep tiny particles called dust from getting into your lungs. Dust is made up of little pieces of things like dirt, pollen, and other small particles that can be harmful if you breathe them in too much.

The dust mask blocks these particles from entering your nose and mouth by trapping them in a filter. Just like a strainer catches noodles when you pour them out of a pot, the filter in your dust mask catches dust particles as you breathe in.

It's important to wear a dust mask when you're doing things like sweeping, sanding, or doing other work that creates a lot of dust. This way you can still breathe safely and not risk hurting your lungs.

The dust mask is a small but important piece of safety equipment that helps protect your health!
