Does nasal hair have any useful function?
Everyone has them and its a good thing too! Your nose hairs act as a natural filter to prevent the entry of dust, pollen, spores, viruses and bacteria.

Certainly! It’s a filter for dust, pollen, spores, viruses and bacteria. Particles stick to the wet surface of your nose hairs, which prevents them from reaching your lungs and causing infection. Eventually you’ll either blow the nasties into a tissue, or swallow them, to be destroyed in your stomach.
