What is the function of nose hairs?

Nose hairs act as a physical barrier that traps large airborne particles, like dust and pollen, preventing them from entering the nasal passages. This filtration helps keep debris and potential pathogens from reaching the lower airways. Warming and humidifying air come primarily from the nasal mucosa and turbinates, not the hairs themselves, while detecting odors is the job of the olfactory epithelium higher in the nasal cavity. So the filtering function is the best description of what nose hairs do.
