The air passes through the NOSE, which has mucus membranes that clean/moiston air, as well as hairs (cilia) that attach to dirt and dust particles to keep them out of the rest of the respiratory tract.
Final Answer: Nose
The mucous membranes in the mouth and nose are physical barriers against infection. The membranes function to filter particles and microorganisms out of the air that is being inhaled.
Mucous membranes and cilia in the trachea trap and eliminate particulate matter from inhaled air. The membranes also warm and moisten incoming air.

Are mucous membranes sterile
ciliated mucous membranes
believe it or not, mucous membranes secrete mucous. It helps protect the respiratory system (or whichever system the mucous membrane you're referring to is in).
Mucous membranes or mucosae are "wet" membranes. This is because they are continously bathed by secretions, except the mucous membranes of the urinary tract that is continously bathed with urine. Mucous, serous, and synovial

Mucous membranes.
The upper respiratory system cleans and warms the air even before going into the lungs. Tiny hairs in the upper tract remove particles which have become stuck in mucous made by the membranes. These same membranes warm and add moisture to the air before it reaches the alveoli.
