The microscopic hairs in the airway that help keep dirt and other particles out of the lungs are called cilia. These tiny, hair-like structures line the respiratory tract and work in tandem with mucus to trap and move foreign particles and pathogens upward toward the throat, where they can be swallowed or expelled. This mechanism is crucial for maintaining respiratory health by preventing the accumulation of harmful substances in the lungs.
There are tiny hairs called Cilia which lines the airway. Possibly this is what you are thinking about. These tiny hairs trap dirt particles in the air and move them out of the lungs.
The Windpipe, also known as the trachea, is the airway from the mouth to the lungs.

The nose, pharynx, and trachea are the parts of the upper airway. The tubes of the lungs comprise the lower airway.
from nose through airway in throat into lungs
The trachea is the primary airway in the respiratory system, connecting the larynx to the bronchi. It is responsible for carrying air to and from the lungs during breathing.
The ciliated cells has tiny hairs on it, called cilia, which sweep mucus, which is produced by goblet cells, up the airway. The mucus traps dirt particles and stop them from entering the lungs and causing infection. The ciliated cell therefore sweeps mucus up the airway where it is either swallowed or coughed out.
