Hair in the nose is one of the body's first lines of defense against harmful environmental pathogens such as germs, fungus, and spores.
Another purpose for nose hair is to provide additional humidity to the inhaled air. As the air passes through the nasal passages, the mucus and hair provide heat and moisture. Humidity is an important factor for the rest of the respiratory system, such as the larynx and lungs.
Hair in the form of tiny cilia also draw solid particles towards the interface between the nose and throat. Harmful debris is generally directed towards the back of the throat and esophagus for swallowing, while the filtered air continues towards the larynx and lungs.
