      I think nose hairs are there to catch dust and insects and anything else that you might breathe in, so that all that dirt doesn’t reach your lungs. Instead it stays in your nose, where you can easily blow them back out (into a tissue, of course).

      Noise hair is first stage of air filtration. With out this chances of entry to dust mites and small insects are more. Nose hair traps them all and also it helps to collect moisture.

      To strain out the nasty stuff we breathe in. It’s like an air filter in your house or over your cooker. Nose hairs trap dirt, viruses, bacteria and toxins until we blow them out, sneeze, or swallow.

      Hair in the nose is one of the body’s first lines of defence against harmful environmental pathogens such as germs, fungi, 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.

      Nose hair are there as first filtration before reaching the chest.

      We also have them to feel the atmosphere, as sensors.
