It keeps most inhaled dust stuck in your nose so it doesn't get into your body.

The nasal hair traps foreign objects and stops them from reaching your throat where they can be absorbed and can make you sick. For example breathing in mold spores.

When you breathe through your mouth they go straight into your body, but breathing through your nose can trap the spores which you will later sneeze out.

A 'booger" or 'bogey' is a collection of objects that have been caught in your nose hairs and are then covered with your bodies own protective snot-like substance.

That's why it's bad to eat your boogers/bogeys.
