A. They filter out dust and pollen to keep your lungs cleaner.
Nasal hairs (vibrissae) are the first line of defense in the nose: they trap larger particles (dust, pollen, insect bits) so fewer reach the lower airways. The nasal mucosa then traps smaller particles and cilia move mucus out — together helping protect your lungs.
