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 lungs
The Windpipe, also known as the trachea, is the airway from the mouth to the lungs.
feet
The inner walls of the lungs are covered with cilia, small microscopic hairs that are consistently moving in a wave-like flow upwards toward the throat and mouth.
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.
The nose, pharynx, and trachea are the parts of the upper airway. The tubes of the lungs comprise the lower airway.
