The cilia increases the surface area of the cells and epithelium. This is further increased by the convoluted surface of the nasal conchae in the nose particularly.
The extra surface area means that the air is exposed to the temperature of the body and is warmed as it passes through.
The columnar epithelium contains goblet cells which secrete mucous. The mucous serves to trap particles in the air and also to humidify the air as it passes through.
The nose in particular is such an effective humidifier and heat exchanger that by the time air passes from the outside, through the nose and into the larynx it is already at body temperature and optimal humidity.

I believe that the air just passes through it like a filter.
think of cheesecloth on a microscopic scale.
ah the third guy is right. trying to trick me with big words.
just say "how does the nose humidfy and warm air" next time.
