Detailed answer: Healthy cilia (nose hairs) beat in a coordinated backward-&-forward motion on an average of sixteen times per second. Biologically, the cilia act as a filter and keep dust and dirt out of the nasal passages. They also draw liquid mucus up from the epithelium by capillary action, and thus help to maintain humidity in the air passages by trapping humidity as one exhales, while evaporation of trapped moisture on the hairs humidifies inhaled air. Cilia are in motion, beating several times per second. By this action, the ciliated cells push mucus back in towards the oropharynx where it can be either swallowed or ejected, a mechanism much like that by which the cilia in the ear canal remove cerumen and other detritus. Exposure to cold is thought to slow the vibration of the cilia, contributing to the buildup of mucus; diesel fumes and other pollutants are thought to have similar effect.

To put it as simple as I can. They are used as a filter.
-
To catch air pollutants such as dust out of our system. It is a trap that gathers the debris and is where the mucus can "garbage collect," so to speak, and mucus is then ejected from the body via a blowing nose onto a tissue into the trash, and hopefully not the recycle bin.
